This test is suitable for legal cases requiring reliable evidence. Call (877) 731-6362 to arrange testing. OVERVIEW ## What is a 19-panel hair follicle drug test court admissible? A 19-panel hair follicle drug test [court admissible](https://amhnationwide.com/hair-testing-court-admissible/) is a comprehensive drug screening that detects the presence of 19 different substances using a hair follicle sample. Its design ensures the test results meet legal standards for admissibility in court through strict chain of custody procedures, certified laboratory analysis, and review by a Medical Review Officer (MRO). This test is often requested in legal, forensic, or employment contexts where drug use evidence must be defensible under legal scrutiny. CHAIN OF CUSTODY ## How does chain of custody ensure the test is court admissible? Chain of custody is a documented process that tracks the hair follicle sample from collection through laboratory analysis and reporting. It ensures the sample is not tampered with or contaminated and that the identity of the donor is verified at every step. AMH Nationwide directs the requester to authorized collection sites where trained personnel collect samples following strict protocols. Each sample is accompanied by detailed documentation that travels with it to the lab and back. Sample collection by trained professionals at authorized sites Donor identification verification at collection Sealed and labeled specimen containers Documentation accompanies the sample throughout transport Secure handling by certified national labs CERTIFIED LABORATORIES ## Which labs analyze the 19-panel hair follicle drug test for court use? Testing is performed by one of five national laboratory networks: [Quest Diagnostics](https://www.questdiagnostics.com/), [LabCorp](https://www.labcorp.com/), Omega Labs, United States Drug Testing Labs, and ExperTox. These labs are certified and accredited to meet forensic and legal testing standards. Using multiple certified labs ensures results are reliable, reproducible, and accepted in court proceedings. Quest Diagnostics LabCorp Omega Labs United States Drug Testing Labs ExperTox MEDICAL REVIEW OFFICER ## What role does the Medical Review Officer (MRO) play in legal defensibility? Every non-negative result from the 19-panel hair follicle drug test undergoes review by a certified Medical Review Officer (MRO). The MRO evaluates lab findings in the context of the donor’s medical history and prescription information to confirm or refute positive results. This step reduces false positives and provides a medically sound interpretation essential for court admissibility. ## Ready to Schedule a 19-Panel Hair Follicle Drug Test Court Admissible?

Test results are released only to the authorized requester specified by the individual or organization ordering the test. This strict control maintains confidentiality and chain of custody integrity. AMH Nationwide does not release results directly to the tested individual unless they are the authorized party. Documentation and reporting comply with legal requirements. TESTING LIMITATIONS ## What are the detection windows and substances tested in a 19-panel hair follicle drug test? The 19-panel hair follicle drug test detects drug use typically within a 90-day [detection window](https://amhnationwide.com/hair-follicle-drug-test-detection-window/) by analyzing hair strands for metabolites of drugs. It covers a wide range of substances including opioids, amphetamines, cannabinoids, cocaine, PCP, and others. Hair testing is not suitable for DOT-regulated safety-sensitive positions, which require federally certified [urine](https://amhnationwide.com/urine-drug-testing/) protocols. However, hair testing offers longer detection periods and resistance to adulteration. Detection window: up to 90 days Drugs tested include but are not limited to: Amphetamines Cocaine Opiates Phencyclidine (PCP) Cannabinoids Benzodiazepines Barbiturates Methadone Propoxyphene MDMA (Ecstasy) Oxycodone Hydrocodone Others as per panel specifics ORDERING PROCESS ## How do I arrange a 19-panel hair follicle drug test court admissible?
