DNA Testing in Houston, TX


Everyone is born with a unique blueprint which is called DNA. Half of which comes from the father and the other half from the mother. We provide DNA testing in Houston, TX, which is a conclusive way of identifying biological relationships.

The DNA test results have a 99.999999% degree of exclusion. That means on a DNA paternity test, there is 99.999999% chance of proving that you are not the father.

The procedure is painless. A sterile swab of the cheek is done to collect a DNA sample for testing.

Results for DNA testing are back within 48 business hours but can be expedited to be back within 24 business hours.

There are two types of tests that can be done:

1) Legal Test – The sample must be collected by an independent third party who completes the proper chain of custody documents and verifies the identity of each individual tested. This form of testing is admissible in court.

2) Non Legal Test – The sample can be done by an independent collector or done by you in the privacy of your home. The results of this test are not admissible in court, but can be used to alleviate any doubts you may have or satisfy any suspicions you may have before moving forward with the expensive legal process. To do the test at home, an at home DNA identification kit can be ordered by calling, (832) 831-8121. Instructions on how to correctly collect the sample will be provided.

DNA is found in virtually every cell in the body. The body is constantly shedding cells from different parts of the body e.g., hair, saliva and skin. This DNA evidence can last for decades if the conditions under which it is stored are right. Things like bacteria, mold, moisture and sunlight can affect the life span of the DNA evidence.
