11. What is a multi-panel drug test?

A multi-panel drug test is designed to detect multiple drug classes simultaneously.

Examples include:

• 6-drug tests
• 7-drug tests
• 8-drug tests

Multi-panel devices allow employers to screen for several substances using a single specimen.

Onsite Diagnostics has a range of products that also incorporate an Alcohol test so you can screen for both drugs and alcohol in one comprehensive test.

• -          Saliva Swipe 8 Advanced + Alcohol
• -          Clearline 6 Advanced + Alcohol
• -          Eco 7 Advanced + Alcohol

This improves efficiency and reduces testing time.

12. What is the difference between a 6-drug and 8-drug saliva test?

The difference is the number of drug classes screened.

A typical 6-drug saliva test may detect:

• THC
• Amphetamine/Methamphetamine
• Cocaine
• Opiates
• Oxycodone

An 8-drug test, like the Saliva Swipe 8 Advanced + Alcohol includes additional drug classes such as benzodiazepines, Ketamine and K3 Synthetic Marijuana. Plus an option of Alcohol.

The appropriate device depends on workplace requirements and risk assessments.
