The Non-Negative Confirmation Test is used in the case you obtain a positive result on a drug test. This test provides confirmation and a chain of custody form with a prepaid shipping label for a positive result. Just fill out the form and include the positive test to send to the lab. We'll confirm your results.
The Chain of Custody Form is valid for one year after the date of purchase.
