What does a 50 ng/mL cut-off mean on a THC drug test?

A 50 ng/mL cut-off is the federal standard for detecting THC in urine. Results above this level are positive for marijuana use; results below this level typically indicate a negative test result.

How long does THC stay in the system?

For occasional users, THC stays detectable about 3–7 days; regular users, 7–21 days; chronic heavy users can test positive for up to 30 days or longer.

Can second-hand marijuana smoke cause a positive test?

No, normal second-hand marijuana smoke exposure won’t typically cause a positive THC test at the 50 ng/mL threshold unless exposure is prolonged, intense, and in an enclosed space.

What does a faint line on the THC test mean?

A faint line means negative for THC. Line intensity doesn’t affect accuracy—any visible second line (even faint) indicates THC levels below the 50 ng/mL cut-off, thus a negative result.

Is Exploro’s THC 50 ng/mL home test accurate?

Yes, Exploro’s THC 50 ng/mL test is providing results comparable to laboratory screenings and precisely meeting federal workplace testing standards.
