DNA Viability Test

A DNA viability test is performed on unusual samples to check for the presence of usable DNA for a paternity or other DNA tests. In paternity cases where the alleged father is missing or unavailable, we may be able to use preserved samples such as blood, hair, or other body tissues.

If you have samples that might be used in a viability test, please call to discuss this possibility with one of our consultants. He or she will tell you the probability of obtaining usable DNA from the sample, and specify a viability test fee.

You will need to provide the following information when you call:

The age and storage condition of the sample.
The size or amount of available sample.

The viability test fee is variable and depends on sample type and condition. This non-refundable fee is separate from the paternity test fee and needs to be paid before testing begins.

If the viability test reveals the presence of usable DNA, our consultants will call you to arrange sample collection for the other test participants. A standard DNA test will then proceed.
