Did you know they both have the same readings? Yes, a negative urine test reads = two T lines and a positive reads – one C line only.
All saliva drug test in oral fluids read precisely the same. 2 T lines is a negative, 1 C line is positive.
Faint lines are where many people get confused. Did you know, a faint line counts as the presence of a line read on all types of drug testing devices? So, if you see a dark C line along with a faint T line, that is a negative reading. A positive result reading is no T line at all on both the urine drug test and the saliva drug screen.
