your cannabinoid levels have gone up. "40 ng/ml" means 40 nanograms per milliliter. "66 ng/ml" means 66 nanograms per milliliter. so there were more cannabinoids in the second urine test than in the first. hope that makes sense.
what does cannabinoids ur-mcnc: 40 ng/ml mean. my first urine test showed cannabinoids ur-mcnc: 40 ng/ml then 30 days later the results showed cannabinoids ur-mcnc: 66 ng/ml. my question is have my levels gone up or have they gone down?
