Call (877) 731-6362 today. --- Hair follicle drug test for court & custody is used to provide a detailed drug use history over 90 days, critical for legal proceedings involving child custody or court requirements. This test uses hair samples collected under strict chain of custody and is reviewed by a certified Medical Review Officer. Call (877) 731-6362 to schedule your collection. PURPOSE ## Why is a hair follicle drug test used for court and custody cases? A hair follicle drug test for court and custody cases is employed to deliver a comprehensive, long-term record of drug use, covering approximately 90 days. Courts rely on this test because it is less susceptible to tampering compared to [urine](https://amhnationwide.com/urine-drug-testing/) or saliva tests and offers a broader [detection window](https://amhnationwide.com/hair-follicle-drug-test-detection-window/), making it a strong piece of evidence when evaluating parental fitness or compliance with court orders. This test is chosen when courts need reliable, objective data to inform decisions about custody, visitation rights, or compliance with [probation](https://amhnationwide.com/hair-follicle-drug-test-probation/) terms. The test’s ability to detect multiple drug classes and its documented chain of custody protocols align with legal standards for admissibility. PROCESS ## What is the process for a hair follicle drug test in court and custody situations? The testing process starts with AMH Nationwide providing a lab order that directs you to one of over 20,000 nationwide collection sites. At the site, trained personnel collect a small hair sample, typically 1.5 inches long, from the scalp to represent approximately 90 days of drug history. The sample is packaged with strict chain of custody documentation to maintain legal integrity and sent to 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. Results are reviewed by a certified Medical Review Officer (MRO) who verifies any non-negative findings before reporting, ensuring accuracy and compliance with court standards. Collection: hair sample about 1.5 inches long Chain of custody documented at collection and shipment Testing performed by [SAMHSA](https://www.samhsa.gov/workplace/drug-testing)-aligned / CAP / CLIA accredited labs Review by certified Medical Review Officer (MRO) before results release LEGAL ## How is chain of custody maintained to ensure court admissibility? Chain of custody is critical to the acceptance of hair follicle drug test results in court and custody proceedings. AMH Nationwide follows rigorous procedures that track the sample from collection through laboratory testing to final reporting. At the collection site, each sample is sealed and logged with unique identifiers. Documentation accompanies the sample during transport to the lab. Labs maintain secure handling and testing protocols accredited by CAP and CLIA. The Medical Review Officer reviews and certifies the final report under SAMHSA guidelines, adding a layer of professional validation recognized in legal contexts. Sample sealed immediately after collection Unique ID tracking throughout process Secure storage and handling at accredited labs MRO review to verify test validity and interpret results WHEN TO CHOOSE ## When should you choose a hair follicle drug test for court and custody? Choose a hair follicle drug test if you need a reliable history of drug use spanning up to 90 days, especially in cases where short-term testing (urine or saliva) might miss intermittent usage. This test is ideal for courts requiring durable, tamper-resistant evidence. It is also suitable when the court order or custody agreement explicitly calls for long-term drug monitoring or when repeat testing is planned to assess ongoing compliance. Hair testing is not subject to rapid metabolism or immediate dilution, making it a preferred choice for evaluating sustained behavior over several months. Need drug use history over 90 days Requirement for tamper-resistant evidence Court mandates long-term monitoring or retesting Evaluating compliance with custody conditions ## Ready to Schedule Your Hair Follicle Drug Test for Court or Custody?

Hair follicle drug testing may not detect very recent drug use within the past 5 to 7 days, due to the time required for drugs to incorporate into hair shafts. This means it cannot confirm last-minute consumption but focuses on patterns over weeks or months. Additionally, hair color, cosmetic treatments, and hair length can affect test sensitivity. Courts and labs interpret results within this context. The test does not detect alcohol levels or some synthetic drugs not incorporated into hair reliably, requiring complementary testing if immediate or specific substances need evaluation.

The exact panel depends on the court’s requirements and the testing lab’s capabilities. Typically, results are available within 3 to 7 business days after the lab receives the sample. The Medical Review Officer’s review is included before final reporting. No, hair follicle drug tests generally do not detect drug use within the prior 5 to 7 days because drugs take time to grow into the hair shaft. For recent use, urine or saliva tests are more appropriate. Hair follicle testing is not accepted for DOT-regulated safety-sensitive positions, which require federally certified urine testing under [49 CFR Part 40](https://www.transportation.gov/odapc/part40). Hair testing is used for non-DOT roles and court-ordered situations. If a test result is non-negative, a certified Medical Review Officer contacts the individual for verification, medical history review, or to request prescriptions to confirm legitimacy before finalizing the report. No, AMH Nationwide does not offer online ordering. To initiate testing, you must call (877) 731-6362 to obtain a lab order and be directed to a collection site.
