What marijuana metabolites am I testing?

THC-COOH is the primary marijuana metabolite screened for in workplace drug testing. Most marijuana drug metabolites are water-soluble and are excreted rapidly from the body. THC-COOH is fat-soluble and thus exits the body slowly.

Med Tech Approved THC TEST screens the presence of THC-COOH in urine and is sensitive to all marijuana metabolites. See manufacturer package insert.

Marijuana Drug Test




Positive result: One color line appears in the “C “ area and no line in the “T” area. A positive result means that THC concentration level in your urine exceeds the federal guideline cutoff level of 50ng/mL.

Negative result: Both “C” and “T” lines have a red intense line. A negative result means THC-COOH was not detected or is below 50ng/mL cutoff level. If "T" line faint in color, we recommend that you detox further until both "C" and "T" lines have the same intense color. This will ensure that your body THC concentration level is very low or negative. Our Med Techs are available to help if you need a second opinion reading your result. Just email us.

Invalid result: Control “C” line fails to appear due to insufficient volume, incorrect testing procedure or test has expired.
