Our testing partner has provided tests for thousands of customers, and is recognized as a leader in the science of DNA testing. Industry-wide, paternity tests are generated using as few as four markers, to as many as 16 markers. Our partner lab uses a 16 marker test that can achieve a probability of > 99.999%. Collecting samples for DNA analysis is an easy and painless process. A sterile swab, similar to a Q-tip is rubbed on the inside of the cheek for 30 seconds, placed into an envelope and sent back to the lab for analysis.
