Hair tests rarely detect acid use. Learn how hair follicle testing works. Call (877) 731-6362 for details. --- Does acid show up in a hair follicle test? Hair follicle drug tests generally do not detect acid (LSD) because of its chemical properties and low concentration in hair. Hair testing is more reliable for substances like opiates and cocaine. For accurate hair follicle testing information, call (877) 731-6362. OVERVIEW ## Does acid show up in a hair follicle test? Acid, commonly known as LSD, is not reliably detected by hair follicle drug tests. Hair follicle tests analyze the hair shaft for drug metabolites that bind to hair proteins. However, LSD is present in the body in very low concentrations and does not incorporate well into hair, making detection uncommon. Hair follicle testing is designed to identify drugs with stable metabolites that remain in the hair for weeks to months. LSD’s chemical structure and rapid metabolism mean it rarely shows up in hair samples even after use. TESTING DETAILS ## How does hair follicle testing work for detecting drugs like acid? Hair follicle tests collect about 1.5 inches of hair, representing approximately 90 days of drug use. The hair is tested for drug metabolites absorbed into the hair shaft from the bloodstream. The test is highly reliable for substances such as opiates, cocaine, methamphetamine, and cannabinoids. For acid, the challenge is that LSD metabolites are unstable and present in very low amounts, so standard hair tests do not routinely include acid in their screening panels. Specialized testing methods would be required, which are not common in standard hair follicle drug tests. LAB NETWORKS ## Which labs process hair follicle tests for acid detection? AMH Nationwide routes hair follicle tests through five national lab networks: [Quest Diagnostics](https://www.questdiagnostics.com/), [LabCorp](https://www.labcorp.com/), Omega Labs, United States Drug Testing Labs, and ExperTox. None of these labs include LSD in routine hair follicle drug test panels due to the low detectability. Every non-negative screen undergoes review by a certified Medical Review Officer (MRO) to ensure accuracy and proper interpretation of results. For DOT-regulated safety-sensitive testing, hair is not used; [urine](https://amhnationwide.com/urine-drug-testing/) is the required specimen under federal guidelines. [DETECTION WINDOW](https://amhnationwide.com/hair-follicle-drug-test-detection-window/) ## What is the detection window for acid in hair follicle testing? If LSD were detected in hair, the detection window would theoretically be up to 90 days based on hair growth rates. However, due to LSD’s low incorporation into hair, positive results are extremely rare. Most hair follicle tests do not reliably detect acid at any time frame. This contrasts with urine or blood testing where acid may be detected within hours to days after use, but these tests have shorter detection windows compared to hair. ## Need Accurate Drug Testing?

AMH Nationwide provides lab orders and directs clients to one of over 20,000 nationwide collection sites. There is no online ordering for hair follicle tests. To arrange testing or get a quote, call (877) 731-6362. Collection involves a brief hair sample taken close to the scalp by trained personnel. The sample is then sent to one of the five national labs for analysis. Pricing varies based on the test panel and detection window. TEST LIMITATIONS ## Can acid use be reliably detected or ruled out with hair follicle testing? Due to the low concentration and chemical properties of LSD, hair follicle testing is not a reliable method to detect acid use. Negative results do not guarantee absence of use, especially for LSD. Employers, courts, or [probation](https://amhnationwide.com/hair-follicle-drug-test-probation/) agencies requiring LSD detection typically use urine or blood testing methods. Hair testing remains effective for many other drugs but is limited for acid detection. AMH Reviewed & Maintained By AMH Nationwide Customer Service AMH Nationwide is BBB A+ accredited and routes every order through Quest Diagnostics, LabCorp, Omega Labs, United States Drug Testing Labs, or ExperTox, all of which use multiple lab certification agencies and standards such as [SAMHSA](https://www.samhsa.gov/workplace/drug-testing)-aligned laboratory protocols, the ANSI National Accreditation Board for forensic testing and calibration, the College of American Pathologists (CAP), and Clinical Laboratory Improvement Amendments (CLIA). Every non-negative screen is reviewed by a certified Medical Review Officer as part of standard processing before a result is released, and chain-of-custody documentation is maintained on every collection.

Routine hair tests do not typically screen for acid. LSD has a unique chemical structure and is metabolized quickly, resulting in low levels in the bloodstream and hair. This makes it difficult for standard hair tests to detect acid use. Hair follicle tests commonly detect opiates, cocaine, methamphetamine, amphetamines, cannabinoids, and phencyclidine (PCP). Acid is not usually included in standard panels. Even within the 90-day detection window of hair testing, acid is rarely detected due to its poor incorporation into hair, so long-term detection is unlikely. No. DOT-regulated testing requires urine samples under [49 CFR Part 40](https://www.transportation.gov/odapc/part40). Hair tests are not accepted for safety-sensitive positions regulated by DOT. AMH Nationwide does not offer online ordering. To arrange testing, call (877) 731-6362 for lab orders and collection site directions.
