The price is $145 for EACH test involved (except semen test which is $90). If you are needing to see if DNA is present and want to compare that DNA to a sample, you will have to pay $145 for the standard DNA Detection test and another $145 for the DNA Comparison test, for a total of $290. If you also want to see if semen is present, that is an additional $90.
The lab does not offer the DNA Differential Extraction any more. The lab cannot test to see if female DNA is present. The only test for gender is the DNA Detection Y Chromosome, which tests to see if male DNA is present and completely ignores any female DNA. If you'd like to see if male DNA is present and compare that to their own, the charge is $145 for the DNA Detection Y Chromosome and another $145 for the DNA Comparison.
