Drug Test Comparison
4U Health Drug Tests measure either 78 targets in urine or 54 targets in saliva.
– Urine drug tests have a longer window to detect past drug use (1-10 days).
– Saliva drug tests are more convenient to administer, have a faster detection time (6 hours to 6 days), allow observation of sample collection, and do not require an on-demand urine sample.
Review the targets and detection windows to find the right test for your needs.
