How does the process work?
First you order your drug test online or with a quick phone call. You are issued a donor pass which is what you take to the drug testing center near you. You provide your specimen, urine or hair; and the required paperwork is completed. Within a few business days you will get your drug test result which is reviewed and verified by a Medical Review Officer (MRO).
Many options for your drug testing:
Drug Testing Detection Times
- Urine Drug Testing – most drugs will be detected for 3- 4 days, marijuana may be longer for a heavy smoker
- Hair drug testing – drugs can be detected for up to 90 days with 1.5 inches of head hair or body hair.
Can I test positive from second-hand smoke?
- No, the laboratories are sophisticated and perform stringent testing with cut off levels designed to rule out second-hand smoke and even over the counter medications.
- The testing process involves an initial screen and for non-negative results a confirmation process with technology known as gas chromatography (GC), gas chromatography-mass spectrometry (GC-MS) or liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS).

What about legal marijuana?
I only need testing for marijuana, what test panel should I order?
- For a test only for marijuana we recommend you still order the 5-panel drug test. This includes the marijuana testing and is less expensive than a test only for marijuana. In addition, you will get your drug test results back much quicker with the 5-panel drug test. Testing for single drugs is more expensive and take longer to get results.
