Call (877) 731-6362. OVERVIEW ## What substances does the 19-panel hair follicle drug test screen? The 19-panel hair follicle drug test what it screens includes a wide array of drugs and their metabolites to identify recent and past use. This panel covers 19 drug classes, making it one of the most comprehensive hair drug tests available. It detects substances incorporated into hair strands typically over a 90-day window. Amphetamines (including methamphetamine and MDMA) Cocaine and metabolites Marijuana (THC and metabolites) Opiates (morphine, codeine, heroin metabolites) Phencyclidine (PCP) Benzodiazepines Barbiturates Methadone Propoxyphene Oxycodone Oxymorphone Tramadol Fentanyl Buprenorphine Ecstasy (MDMA) MDA (Methylenedioxyamphetamine) MDEA (Methylenedioxyethylamphetamine) Hydrocodone Hydromorphone Each substance group includes parent drugs and relevant metabolites to improve detection accuracy and reduce false positives. PANEL SIZE ## How does the panel size affect what the 19-panel hair follicle drug test screens? The panel size directly determines the number and types of substances detected in the hair follicle test. A 19-panel test offers broader coverage than smaller panels such as 5, 7, or 12 panels, enabling detection of less common prescription and synthetic drugs. Smaller panels focus on a limited set of common drugs like marijuana, cocaine, opiates, amphetamines, and PCP. The 19-panel test expands to include synthetic opioids, benzodiazepines, barbiturates, and newer designer drugs. Larger panels provide more comprehensive results but may increase testing costs and complexity. Choosing a 19-panel test is appropriate when a detailed substance use history is required, such as in legal cases or thorough employment drug screening. [DETECTION WINDOW](https://amhnationwide.com/hair-follicle-drug-test-detection-window/) ## What is the detection window for the 19-panel hair follicle drug test? The 19-panel hair follicle drug test detects drug use typically within the past 90 days. Drugs and metabolites are deposited in the hair shaft from the bloodstream and remain detectable as the hair grows. Hair samples are usually taken from the scalp, approximately 1.5 inches to represent about 90 days of growth. This detection window is longer than [urine](https://amhnationwide.com/urine-drug-testing/) or saliva tests, which detect more recent use. Hair testing does not detect very recent drug use within the last 5-7 days due to the time needed for drugs to incorporate into hair. This extended window makes the 19-panel hair follicle test suitable for monitoring long-term abstinence or historical drug use patterns. WHO ORDERS ## Who typically orders the 19-panel hair follicle drug test and why? Employers, legal professionals, and government agencies often request the 19-panel hair follicle drug test for its comprehensive detection capabilities. It is used to verify long-term abstinence or identify a broad range of substances. Workplace drug testing programs requiring detailed screening beyond DOT-regulated substances. Legal cases such as [child custody](https://amhnationwide.com/hair-follicle-drug-test-child-custody/), [probation](https://amhnationwide.com/hair-follicle-drug-test-probation/), and court-ordered drug monitoring. Rehabilitation programs monitoring patient compliance over months. Insurance companies assessing risk related to substance use. Because the hair test is non-DOT regulated, it is not used for safety-sensitive DOT roles, which require urine testing under federal protocols. ## Schedule Your 19-Panel Hair Follicle Drug Test Today Contact AMH Nationwide to arrange comprehensive 19-panel hair follicle testing through our national lab network.

Results are typically available within 5 to 7 business days after sample collection, depending on the lab network processing the test. Hair color and texture can influence drug incorporation slightly, but labs use standardized methods to minimize bias and ensure accurate results. No, hair testing generally does not detect drug use within the past 5 to 7 days because it takes time for drugs to integrate into the hair shaft. No, DOT-regulated testing requires federally certified urine testing under [49 CFR Part 40](https://www.transportation.gov/odapc/part40). Hair follicle tests are for non-DOT roles.
