I bought some THC screening tests and have been using them to estimate the THC content in my urine. I do this by making a dilution series and testing each concentration to determine upper and lower bounds for the undiluted sample.

The screening tests have a sensitivity of 50 ng/ml. Today I tested 10%, 3%, and 1% dilutions. The 10% was positive but the 1% and 3% tests were negative. That means the actual THC content was somewhere between 500ng/ml and 1667 ng/ml.

I’m planning on testing myself every few days when I’m on my T-break to see if I can figure out how long it will take to get under 50 ng/ml and test clean with an undiluted sample.

I have not started my T-break yet. I am still “tapering.” 🙄
