Special Instructions

Intentional contamination with soap, salt, vinegar, etc. will interfere with the assay, and dilution with water will tend to produce negative results, so the urine collection should be supervised wherever possible.

8-ß-Dihydroxy-d9-THC 50 µg/L
8-ß-Hydroxy-d9-THC 65 µg/L
11-Hydroxy-d8-THC 80 µg/L
