Drug Test Detection Times & Cut Off Levels
Drug test detection times and cut off levels for urine and saliva drug testing kits
Detection times for drugs
The time that drugs can be detected on a drug test varies depending on the type of drug test kit used, and also the brand of drug testing kit that is used. This is often referred to as the window of detection for a drug. As a general rule drugs can be detected longer in urine than in saliva.
Urine drug test detection times & cut off levels

How long are drugs detectable in urine and saliva?
Cut-off levels for drug test kits are brand specific and as a guide, the window period for drug detection using a saliva or oral fluid drug testing kit are shorter than the comparable urine drug test.
The amount of time drugs stay in the body and can be detected on a drug test depends on many factors such as:
- The amount of the drug that has been taken
- The strength and purity of the drug taken
- The body weight of the person being drug tested
- The rate of metabolism of the individual being tested
- Whether the person being tested is a casual drug user or a long-term user.
- Cut-offs are brand specific and as a guide, the window period for drug detection using saliva or oral fluid drug test are shorter than the comparable urine test.
Oral fluid saliva drug test kit detection times
Oral saliva drug test detection times tend to be shorter, when compared to the equivalent detection times in a urine drug test. This can be useful particularly for employers, as it is a good indication of whether an employee is 'under the influence of drugs at work' The dose of the drug taken has a significant effect on the clearance times.
