Maternity Testing

Maternity testing is normally performed by testing a potential mother and a child. This type of testing would normally be requested by an adoption or immigration agency.

If there is more than one possible mother of the child and the possible mothers are closely related to each other, then it is very important to test them both. This would be true, for example, if two potential mothers are related to each other as sisters or as mother and daughter. The DNA maternity test of a single alleged mother only identifies a probability of maternity for that alleged mother compared to other unrelated women. If two possible mothers are closely related, then their genetic makeup can be very similar, and they could both receive a positive test result. In that case, PTC Laboratories will continue testing until one of the alleged mothers is excluded (at no extra charge). If only one of the related alleged mothers is available, the client can pay the laboratory to perform additional testing in order to establish a likelihood that the tested woman is the biological mother as opposed to the unavailable relative. But it is best to test all related parties who could be the mother of the child. Click here for pricing.
