Urine Drug Testing+

Less accurate and reliable compared to laboratory analysis.

POCT often reports false positives especially if the employee is taking legal medications that fall into the same class of substance as illegal drugs.
Chances of false positive=5% Chances of false negative = 40% *

POCT is unable to distinguish between individual compounds, and therefore only reports the class of drug. In other words, a POCT can test for the metabolites of opiates but not tell if it is specifically heroin.

The sensitivity of the POCT device varies based on manufacturer, target compound and the threshold set for detection. (High Cutoffs)

Typically, doesn’t test for specimen validity and sample adulteration

It is more reliable and accurate compared to on-site POCT. Immunoassay technology has an accuracy rate of over 99 percent

The reagents used are more Specific and Sensitive to the drug classes

Specimen Validity Testing can detect whether or not a urine specimen has been tampered with prior to testing

Lab performs Daily QC checks, Weekly Calibrations, and Ongoing Proficiency testing programs. This greatly reduces the chance of false test results.

Lab staff have higher levels of expertise/training in the conduction and interpretation of tests.

The results can be stored for future medical or legal access.
