TEST BASICS ## What substances does the 7-panel hair follicle drug test screen? The 7-panel hair follicle drug test what it screens covers seven common drug classes. It analyzes hair samples to detect drug metabolites embedded in the hair shaft, reflecting use over approximately 90 days. This test typically includes the following substances: Amphetamines: Includes methamphetamine and related stimulants. Cocaine: Detects cocaine and its metabolites. Marijuana (THC): Screens for tetrahydrocannabinol compounds. Opiates: Includes morphine, codeine, and heroin metabolites. Phencyclidine (PCP): Detects the hallucinogenic drug PCP. Benzodiazepines: Includes common prescription sedatives like diazepam. Barbiturates: Screens for sedative-hypnotic drugs. These seven drug classes compose the standard panel for hair follicle testing ordered in many workplace, legal, and rehabilitation contexts. PANEL DETAILS ## How does the panel size affect what the 7-panel hair follicle drug test detects? The panel size directly determines the range of substances screened. A 7-panel test focuses on the most commonly abused drug categories but does not include less common or emerging drugs. Larger panels, such as 10-panel or 12-panel hair tests, add substances like synthetic cannabinoids, opioids like oxycodone, or methadone. 7-panel: Covers seven primary drug categories as listed. 10-panel: Adds substances like oxycodone, methadone, and synthetic cannabinoids. 12-panel and above: May include additional opioids, designer drugs, or expanded benzodiazepines. Choosing the 7-panel hair follicle drug test provides focused coverage suitable for many standard drug screening needs, especially where DOT regulations do not apply. TEST USES ## Who typically orders the 7-panel hair follicle drug test and why? The 7-panel hair follicle drug test is often ordered by employers for [pre-employment](https://amhnationwide.com/pre-employment-hair-testing/) screening, random employee testing, or legal cases requiring drug use history. It is favored for its extended [detection window](https://amhnationwide.com/hair-follicle-drug-test-detection-window/) and resistance to sample tampering compared to [urine](https://amhnationwide.com/urine-drug-testing/) tests. However, it is not used for DOT-regulated safety-sensitive positions, which require federally certified urine testing. LAB PROCESS ## How is the 7-panel hair follicle drug test processed by the lab? AMH Nationwide routes hair follicle samples through one of five national lab networks: [Quest Diagnostics](https://www.questdiagnostics.com/), [LabCorp](https://www.labcorp.com/), Omega Labs, United States Drug Testing Labs, or ExperTox. After collection at an authorized site, the sample undergoes initial screening. Any non-negative result is reviewed by a certified Medical Review Officer to confirm findings and rule out legitimate medical explanations. ## Need a 7-Panel Hair Follicle Drug Test?

The 7-panel hair follicle drug test detects drug use typically within the past 90 days. Hair grows approximately half an inch per month, and standard collection samples 1.5 inches of hair. This extended window allows detection of drug metabolites long after they are no longer present in blood or urine, making hair testing effective for establishing longer-term drug use history.

Extended panels are required to detect these substances. No, DOT-regulated testing requires federally certified urine testing under [49 CFR Part 40](https://www.transportation.gov/odapc/part40). Hair follicle testing is for non-DOT safety-sensitive roles. Results typically take 3 to 5 business days after sample collection, depending on the lab network processing the test. A certified Medical Review Officer reviews all non-negative results to confirm drug use or identify legitimate medical explanations before final reporting. Certain hair treatments like bleaching or dyeing may reduce drug metabolite levels, but labs use methods to minimize false negatives. It is important to disclose any hair treatments during collection. A small sample of hair, usually about 1.5 inches long and the width of a pencil, is cut close to the scalp from the crown area to ensure accurate detection of recent drug use.
