The 3 medical-grade tests provided in NicoClean Detox measure the concentration of cotinine in your body at a threshold of 200 ng/mL (nanogram per milliliter). If the test detects an amount of cotinine over that threshold, then you will test positive for having recently used nicotine products. If the test detects under this amount, then your test will come back negative or clean.
This is very similar to tests that are administered for official use (insurance, sports, jobs, etc.), so if you pass one of our tests, there is an excellent chance that you will pass your upcoming test.
