ajamufua Reviewed by ajamufua on . Urine Test Confirm Cutoff/Error Question Knew a test was coming so abstained for 10 days & drank water like crazy. Picked up two home tests from local drug store & both home tests said I passed (negative result). Submitted to official medical test and came up positive by 4ng/mL: Screening Cutoff = 50 ng/mL Confirm Cutoff = 15 ng/mL Confirm Quantity = 54 ng/mL If the confirm cutoff is 15ng, shouldn't a positive need to be at least 65ng (50+15)? Isn't the 15ng the error threshold? If not, what is "confirm cutoff" ? Rating: 5
