A DNA sample 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 there are samples which might be used in a viability test, please call
Paternity Express 1-888-312-4362 to discuss this possibility with one of our
case managers, who will tell you the probability of obtaining usable DNA
from the sample, and specify a DNA sample viability test fee.

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

• Name and contact information of the coroner, medical examiner, hospital, funeral home or any other facility who is in possession of the sample.
• Age and storage condition of the sample.
• 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.
