Drug Testing FAQs
What does a multi-drug screen test for, and what can it miss?
A multi-drug screen checks one urine or saliva sample for several drugs or drug groups. Depending on the kit, these can include cannabis, cocaine, amphetamines, opiates and MDMA. It only checks the substances listed for that test.
What do 5-panel, 10-panel and 13-panel mean?
The panel count tells you how many separate checks a kit contains. These numbers do not refer to a universal drug list. Two 10-panel drug test kits can check for different substances.
Rezure’s 5-panel saliva kit checks cannabis, cocaine, amphetamines, opiates and MDMA. Our 13-panel urine cup also includes checks for substances such as ketamine, benzodiazepines and methadone. Read the full list before choosing.
What can a multi-drug test miss?
A panel cannot reliably detect drugs it was not designed to check. For example, an opiates screen does not reliably detect fentanyl, which needs a specific test. This does not mean fentanyl cannot be detected in urine.
Even a covered drug can go undetected if you test outside its detection window or the concentration falls below the test’s cut-off. A negative result does not prove that no drugs have been taken.
Before you choose a kit
If the substance you need is not listed, ask a testing provider about a targeted test or laboratory analysis. A larger panel is only useful if it covers what you need.
Rapid tests provide screening results. A non-negative result needs laboratory confirmation before you treat it as definitive.
