Interpretive Data:

Drugs covered: 9-carboxy-THC
Positive cutoff: 5 ng/mL

The drug analyte detected in this assay, 9-carboxy THC, is a 
metabolite of delta-9-tetrahydrocannabinol (THC). Detection of 
9-carboxy THC suggests use of, or exposure to, a product containing 
THC. This test cannot distinguish between prescribed or non-prescribed 
forms of THC, nor can it distinguish between active or passive use. 
The plasma half-life for 9-carboxy THC metabolite is estimated to 
range from 4-12 hours.

For medical purposes only; not valid for forensic use.
