Saliva drug test detection times. Drug detection times simply indicate a specific time in which a test can reveal the presence of a drug in the urine, saliva or hair of the user. The specific time will reveal the first time the drug will show up in your body for the first time you took it and the time your body will be clean.
In order to determine the limit of detection of the method as implemented, set x in the above equation equal to one (1), the theoretical limit of detection of the MPN based method and solve the equation for y. Convert = 1 x to its log value which is zero (0).he terms mx in the equation then cancel out and y is equal to b, the y-intercept of the line. Take the antilog of b, the y-intercept. This value is the limit of detection of the method as implemented.
