Question 1

Why are some synthetic urines flagged for nitrates?

Accepted Answer

Many synthetic urine formulas contain preservatives that can break down into high levels of nitrates when improperly heated. This is a primary reason for a failed test.

Question 2

What is Gas Chromatography-Mass Spectrometry (GC-MS)?

Accepted Answer

GC-MS is a sophisticated lab technique used to separate and identify individual chemical components in a sample. It provides a detailed chemical fingerprint that can reveal inconsistencies, such as those caused by high nitrates.

Question 3

Can nitrates cause a false positive for drugs?

Accepted Answer

While nitrates themselves don't typically cause a false positive for illicit substances, their presence in high concentrations is a red flag for sample adulteration. This can lead to the sample being rejected, which is functionally a failed test.
