Because questions concerning DNA parentage testing can be fairly complex, it is usually easier to discuss them over the telephone. If you are in the United States, we encourage you to call our toll-free number at (888) 837-8323 between the hours of 7:00 a.m. and 8:00 p.m. central time, Monday through Friday.

You can also leave us a message and ask us to return a call to you. You can leave the message either on our voice mail (outside of regular business hours) or by sending us a facsimile or email.

If you are outside the United States, or if you simply prefer to use email, you may send us an email by clicking on:
