Can I Pass a Hair Drug Test Buy Using a Shampoo?
1. What is hair screening? A test for substance abuse that utlizes a small sample of hair to identify specific drugs used by the person being tested. It is the most accurate method of detecting substance abuse. The lab’s state-of-the-art hair screening method uses enzyme-immunoassay (EIA). EIA measures the drug molecules permanently entrapped in the hair which were incorporated following introduction into the body and subsequent adsorption into the bloodstream. 2. How effective is hair screening in detecting drug users? In side-by-side comparison studies with urinalysis, the cocaine, PCP, opiates, and methamphetamine assays have proven hair analysis far more effective than urine in identifying low-level drug use. The marijuana screen is currently less sensitive than the other drugs in identifying low level drug users, but is considered roughly equal to urinalysis in identifying marijuana users. 3. What drugs can be detected in a standard hair screen? Cocaine (cocaine & benzoylecgonine)
