Instructions for DNA Testing

DNA genetic testing is at times suggested as the final means of confirming the biological relationship between a parent and a child for acquisition of citizenship purposes. It is not normally a requirement of the Embassy, and is only suggested in the most problematic of cases. DNA testing, when properly conducted, is virtually 100 percent accurate, and a positive result will assuage any doubt about the parentage of the child.

The Embassy maintains a list of laboratories in the U.S. that are accredited by the American Association of Blood Banks (AABB) to perform genetic testing. The cost of the testing can vary, depending on which laboratory is used and whether or not the results are expedited.

Fees normally range between $600 and $1,000, and the results are available between two and eight weeks after the laboratory receives the samples for analysis. Costs for testing and related charges are borne by the family.

One of the most important aspects of the testing process is the security of the samples taken from the two individuals. The chain of custody must be maintained from the moment the samples are taken by the physician until the kit arrives at the Embassy. Following the instructions below will ensure the validity of the test results.

1) The applicant or his/her guardian must contact the AABB-accredited laboratory in the U.S. to request that they send the testing kit to the Embassy. Authorized laboratories are as follows:
