Accreditations

In forty-nine states there is no law that requires a laboratory that does paternity testing be accredited. Accreditation is the only security you have a client that receives paternity tests that are legitimate and has been made in a way that is likely to produce a reliable conclusion. There are few significant accreditations for testing paternity through DNA. For paternity tests made in the United States, the most important accreditation is the American Association of Blood Banks (AABB). A way to impress potential clients, some laboratories seeking accreditation demonstrate that they have nothing to do with paternity testing. our paternity testing laboratory has the following accreditations, and there are others that might indicate a higher level of skill in DNA analysis, nor more customer value. Links for accrediting agencies are left on each page on the website. American Association of Blood Banks (AABB) – Our paternity testing laboratory is accredited by the AABB. AABB representatives come to our laboratory revisions every two years. Review our protocols paternity testing and equipment, and also inspect all documents belonging to several paternity testing. Ensure that each accredited laboratory is following accepted procedures, and making at least the minimum required level of DNA testing for paternity testing. Forensic Quality Services – ISO 17025 – Our DNA laboratory has international accreditation ISO 17025 for paternity testing and forensic DNA studies. This accreditation is significant for paternity tests whose subjects are people living outside the United States. The company Forensic Quality Services conducts inspections in our laboratory every two years. Department of Health of the State of New York – Our DNA laboratory is accredited by the Department. Health of the State of New York for paternity testing. This agency every two years an inspection of our laboratory. This accreditation is required by the State of New York for a laboratory does paternity testing with residents of this state. New York is the only state that requires a separate verification and essentially duplicate the AABB accreditation. Proficiency Testing – our DNA laboratory and all accredited laboratories receive from accrediting agencies, DNA samples several times during the year for paternity testing. Paternity Testing Corporation is required to process these DNA samples, and send results back to the agencies that issue them . These tryouts are a way for accrediting agencies to ensure that laboratories DNA paternity tests continuously follow scientifically accepted procedures. Our DNA lab receives these specimens from various agencies, including the College of American Pathologists (CAP), the Department. Health of the State of New York, and Forensic Quality Services. The Department. of Commerce of the United States, Certificate of Export Excellence – Although not an accreditation, I include it here because it is the best place to demonstrate this independent recognition of all paternity testing our DNA laboratory performs worldwide.

Choosing a Paternity Laboratory?

When you first decide to get a paternity test, the number of laboratories and resellers can be overwhelming. Moreover, as everyone knows, the internet is full of dishonest sites that seem legitimate businesses but have the sole purpose of taking your money. There are some who give up false paternity test, and some provide a completely unreliable paternity test often gives the wrong answer. This turns out to be a major problem in this area because people do not know what to expect or how the paternity test should work, and have no way to judge the quality of the receiving paternity test. Do not trust what they say. Make sure they are legitimate.

If the website that you. found not show an address with street number nor a direct phone number, you should continue your search. Also, if you are not willing to tell you exactly which AABB accredited laboratory using, you can not trust them. But what to do next?

Fortunately, if you. It is armed with a little information, you can remove easily the worst choices to ask a few questions. How are you questions are very specific, you should get honest answers even disreputable organizations. (It may be a good idea to take notes, with details such as the name of the representative.) You. You can independently verify things like AABB accreditation.

To help protect you from dishonest companies, and to obtain a reliable paternity test, start with a brief call without charge to the lab paternity is considering, and ask:

  1. Does my paternity test will be carried out by a laboratory accredited by the AABB, and exactly which AABB laboratory paternity going to be?
  2. How many locations (also called DNA markers or loci) analyzed in its initial paternity test? (We recommend sixteen locations in the initial paternity test.)
  3. What is your minimum guaranteed paternity probability (recommend a minimum of 99.99%) and is fully applicable warranty if the paternity test without the mother is done, and even if DNA mutations are discovered in the paternity test?

If the laboratory meets these three requirements, and you. AABB accreditation by check, you can feel very comfortable with the paternity lab and receive a very reliable paternity test. In the remainder of this section we discuss why these are the key questions.

Always work with an accredited laboratory by AABB

Paternity laboratories performing DNA analysis are accredited by the American Association of Blood Banks (AABB). In the United States there are no government agencies that oversee laboratories paternity (with the exception of the State of New York), and in many jurisdictions a person or company does not even need a license to trade to be offered to the public as a laboratory paternity . Unless the paternity laboratory is accredited by AABB, the customer has no assurance that the paternity test is done correctly. If you. check AABB accreditation, this ensures that you are using a legitimate paternity lab, and not just a web site designed to take your money.

There are approximately forty-two accredited laboratories paternity in North America (the number varies over time as new laboratories enter the accreditation, and some old stop doing paternity testing).

Some companies, on their website or by phone, claim that they have accreditation by AABB when in fact they do not. You can get a list of laboratories accredited by AABB paternity calling the AABB at (301) 907-6977, or you can click here to browse the site AABB.

If the paternity laboratory is not accredited by AABB, then ud. You have no assurance that its paternity test is valid, or that they even have a concept of what they are doing.

For example, there is a laboratory announces that its staff can obtain a DNA sample from a baby unborn baby looking cells in the blood of the mother. It is a very attractive marketing tactic because it makes one believe that the paternity lab can make a prenatal paternity test with nothing more than a tube of blood from the pregnant woman. Unfortunately, it is not possible to make a reliable paternity test in this way.

The laboratory develops paternity paternity test is covered including a sentence at the end of the DNA report, saying that the paternity test should be repeated after the child’s birth to confirm the result! But DNA does not change after birth. Prenatal paternity test for paternity carried out using chorionic villus sampling (CVS) or amniotic fluid provide exactly the same results as a normal paternity test after the baby is born. Unfortunately, today is not possible to make a reliable paternity test using blood from the mother to obtain the DNA sample of the child.

Paternity Testing Corporation and other accredited laboratories have received many incorrect results of DNA paternity testing done by this laboratory (unaccredited) who claims he can do this. Analysis of DNA Paternity Testing Corporation has done the same people has shown that the original DNA results were incorrect. In particular, these cases are sad because parents sometimes make decisions of life and death for the unborn child based on DNA results from this laboratory.

However, many people still fall into this trap, and pay high costs for prenatal paternity test using blood from the mother. Many resellers in the US advertise this service prenatal paternity test, and then send the DNA samples to the laboratory not accredited paternity claiming to perform the paternity test in this way. Resellers may not realize that the claims are false.

Paternity Testing Corporation has done everything possible to try to warn consumers about the fraud, and has tried to persuade the laboratory offender paternity must stop perpetuating the deception, but the service is being announced yet and victims still believe in DNA results unreliable they receive.

This is nothing more than an example, but there are many others. Unless you. you will do your paternity test with an AABB-accredited laboratory, there is no way to be sure you get a valid result of DNA.

Choose between laboratories accredited by AABB

To AABB accreditation is no guarantee that you. you will receive a correct answer to the question of paternity. As discussed in more detail in the section Avoid Erroneous Results, the minimum level of DNA analysis is not always enough to get the right answer. The laboratories are aware of this reality, but some continue to play nothing but a minimum level for various aspects of the test. As a consequence of this situation, a number of incorrect results issued by accredited laboratories every year.

When you are looking for a paternity test, it’s amazing, it seems that each laboratory accredited swears it’s the best in the entire industry! Some laboratories make specific claims that are obviously false, but there is no way for the public to realize that.

Some accredited by AABB, and also some resellers, laboratories say they are the “best in the world” or “recommended by doctors,” or holding more similar cases to yours, or that their analysis provides results “100% accurate. ” They are statements that can not be tested and in most cases are completely false. Paternity testing is based on probabilities. Paternity Testing Corporation tests more than 40,000 people each year, and to our knowledge have never issued an incorrect result. However, with all precautions and additional analysis Paternity Testing Corporation uses, we can not say that it would be impossible for us to get an incorrect result. It is impossible to guarantee 100% accuracy for inclusionary cases. Many times, ensuring that laboratories provide a less reliable than other accredited test laboratories, but no one can make them desist from using these marketing techniques. Navigating web sites all kinds of ridiculous claims are.

How does a consumer to protect themselves from dishonest business, and choose the best accredited DNA laboratories? Fortunately ud. You can make only two questions paternity lab, and they learn most of what you need to know.

1. Ask: How many DNA locations are included in the initial test lab?

As more locations (loci) DNA are tested, paternity testing is being more reliable. (See Avoid Erroneous Results) Currently, the standard battery test market’s most reliable paternity DNA loci analyzed sixteen. One of these markers sixteen test the sex of the person giving the sample DNA. The other fifteen markers are used to determine paternity. Many laboratories analyze fewer loci. Some tested thirteen, or ten, or even only nine loci DNA. Since it is not necessary to pay more to get a more reliable paternity test, why use a laboratory that analyzes DNA loci less? You should insist on a laboratory that initially sixteen loci DNA analyzes.

2. Ask: What is the guaranteed minimum level of laboratory analysis?

When a laboratory performs its initial battery of DNA analysis, it may not reach its minimum level of discrimination. In this case, they should continue testing more DNA locations, without charging more, to achieve the minimum level required.

AABB requires a lab analyzing continue until a probability of paternity of only 99.0%. At this level of analysis, the laboratory has found a genetic pattern that, on average, is typical of one in every hundred, and in any specific case (including yours), could be even more common than that. Some laboratories insist on doing analysis to achieve a probability of paternity of 99.9%, which is a genetic pattern that, on average, is itself one of every 1,000 men.

Other laboratories continue to analyze, without additional charge, to a probability of paternity of 99.99%, a genetic pattern possessed on average by only one man in every 10,000. A minimum probability 99.99% should be your goal. Get the most reliable test that can not pay more.

But be sure of two things. Make sure it is a guarantee that the test will get a minimum of 99.99%. Do not accept claims about what “normally” get, or they reach “average” or “almost always”, or how their test battery (which is also an average) is qualified. You. You should know that your individual test will be accurate, so you should know what is the minimum accuracy that guarantees the laboratory. Ask to see the written warranty, including the promise to return the money if they fail to comply.

Make sure they guarantee 99.99% even if the mother is not examined, even if the lab found DNA mutations. These are difficult cases, and if the laboratory can guarantee 99.99% in these cases, then is providing a strong analysis in general. So it’s an important question, even if the mother is included in the test.

If a laboratory initially analyzes 16 DNA locations, you will find a mutation in about one of every 35 positive tests. You. Need an exact match for his own paternity test, even if it is a test that contains a DNA mutation.

Some laboratories ensure a guarantee of 99.99%, but unless you. make them the question, or ud. read the small hidden deep in your website letter, will not notice that the guarantee does not apply to his case because the mother was not included in the paternity test, or if the laboratory is a DNA mutation in testing paternity.

To get a paternity test very reliable, insist on using a laboratory that guarantees a 99.99% probability of paternity, even if the mother is not part of the paternity test, and even if the paternity test discovers a mutation of DNA. Some laboratories may ask an additional fee to obtain a reliable result when further analysis is required. The guarantee must be included in the initial price of the paternity test. If further analysis is required to be free for you.

According to our comments in section prevent erroneous results, other laboratory procedures that are also important, but it is very difficult for most people to figure out all the while looking for a paternity test. You must be able to protect themselves dishonored companies, and locate a fairly reliable laboratory, doing nothing simple questions at the beginning of this section. You can accomplish this with a short call without charge each company you are considering. Then verify AABB accreditation by using the link to the site of this organization left on this page.

Paternity Testing Corporation History?

Our paternity testing laboratory was established in the year 1,996. Our DNA testing laboratory is located in Columbia, Missouri, and are among only 42 AABB-accredited laboratories in North America. Our laboratory paternity testing has come to be among the four or five largest DNA laboratories in the US, according to the volume of paternity cases. Do DNA testing with more than 40,000 people each year, from more than 2,000 specimens collection sites across the country, and also conducted international cases worldwide.

Our laboratory paternity testing is a family business. As we are a family, we insist on doing business with conscience and heart. We care much the lives of the people for whom we provide DNA testing. We understand that the question of paternity is an extremely important issue for these people, and we want to be as careful as possible to ensure that the results we provide are completely reliable on the issue of paternity.

People do not realize how much difference in the reliability of DNA testing between laboratories paternity. Accredited laboratories to emit a number of erroneous results each year. But it is possible to make a more reliable test, and some paternity laboratories provide it (see Avoiding Erroneous Results).

As discussed and explained throughout the website, in our DNA testing laboratory operating procedures we adopted that provide higher levels of analysis and implement safeguards to avoid making erroneous results. Because of these methods, we earn less money with every test, but sleep better, knowing that we are not giving incorrect results to the people who trust us to give them the correct answer.

In addition to a higher level of analysis, we focus our mission with conscience and heart and this is visibly in everything you do, from the level and style of customer service, to special prices for people who are forming families through adoption and assisted reproduction.

As ud. will read in comments throughout the website, and as you can confirm with the references we, in our laboratory paternity testing will provide you with the best service and the most reliable DNA test that can be obtained.

Avoid Erroneous Result

Most people assume that all paternity tests are equal, and no matter who you do your DNA test. This could not be further from the truth.

Even if you. you are using an accredited DNA testing laboratory, the required minimum levels are very low. DNA laboratories know that if they do a DNA analysis nothing at the minimum level, a number of results each year will identify a man as the biological father when in fact it is not (a “false inclusion”) or say no it is the biological father when in fact it is (a “false exclusion”).

The paternity testing industry is regulated by the American Association of Blood Banks (AABB, American Association of Blood Banks). The two committees in the AABB establishing requirements for paternity tests are made up of volunteers from private laboratories as our laboratory for DNA samples. Historically these committees have ensured that the DNA labs are following scientifically correct procedures, but have cared less about the level of analysis that DNA laboratories play. The theory is that if a customer wants additional analysis, he can negotiate with the laboratory to pay. The problem is that customers have no way to know if they need further analysis.

So our DNA lab provides additional DNA analysis automatically, without additional charge. Simply put, we are not prepared to issue a report we believe may have the wrong result. It is surprising that many DNA laboratories do not feel the same. A newspaper in Miami, Florida, wrote a very interesting article where the reporter interviewed representatives of several laboratories and demonstrates the wide variety of views on further analysis. Click here to read the article.

Customers who have received evidence from other laboratories, but who doubt the DNA results, sometimes send reports to our DNA laboratory for review. We have received many DNA tests of this kind. In the vast majority of DNA testing, it has correctly identified the tested as the biological father, or have excluded properly man. However, with DNA testing DNA laboratories they have drawn an incorrect conclusion. In these cases, if the client requests that our DNA lab to do the test with the same parties, have been able to obtain the result of correct parenting, explain to the customer the reason why the other DNA lab got the wrong answer, and usually can get the other DNA lab correct its mistake and issue a corrected report paternity.

The problem is that a few cases of incorrect results, customers do not realize that their original DNA test was incorrect. Many live the rest of their lives presuming paternity test has provided the correct answer.

Some factors that cause incorrect results are described below.

False inclusions

The DNA paternity test works by identifying pieces of DNA that have a specific size and come from the biological father. If the tested man has same size pieces, then he may be the biological father. But other men in the population also have the same size pieces. So a laboratory analyzes additional locations (loci) (genetic markers) DNA. Generally, as more locations are analyzed, more infrequent is the genetic pattern in total. In other words, a smaller number of men have the same pattern. As it is the less common genetic pattern, the more likely that the man tested is actually the biological father of the child.

However, if the test is aborted after identifying a genetic pattern that is common, there is a greater probability that the tested man is not the biological father, but one of the people in the population who have this genetic pattern that is common . Therefore, sometimes paternity tests are incorrect because they mistakenly included the tested as the biological father, when he is not a man. These DNA tests are not “technically correct” as they say DNA laboratories that issue, because the report nothing gives a probability that the tested man is the biological father, and not one thing 100% secure. But DNA testing has identified the wrong man as the father, so people have to do with it considered that the outcome of DNA is wrong. We in our DNA lab we completely agree.

These DNA laboratories with more scruples insist on continuing DNA analysis until a pattern that is more rare than the minimum level required, and therefore provide a more reliable DNA test. The industry requires only do analysis to achieve a probability of paternity of 99%. But at this level of analysis, the pattern of DNA identified would be owned, on average, one in every 100 men, and in some cases will be even more common than that. At this level, there are still many men who have the same genetic pattern and who would be identified as the biological father for the test. Some insist DNA laboratories analyze to achieve a probability of paternity of 99.9%, which gives a pattern that, on average, a block with the DNA of a man in 1000. In our laboratory we insist on continuing DNA analysis to achieve a probability of paternity of 99.99%, or a genetic pattern that, on average, corresponds to only one man in every 10,000.
