Located in Garrett, Texas, Accredited Drug Testing offers comprehensive hair follicle drug testing services. Whether you require a drug or alcohol test via hair analysis, our nationwide testing centers are equipped to provide the necessary services. Typically, hair from the head or body that is 1.5 to 2 inches long is needed for testing. Hair analysis can detect drugs, alcohol/ETG, and offers tailored testing options.
Recently, hair follicle drug testing has become a preferred method for drug testing. Employers, legal entities, and substance abuse specialists often opt for hair drug tests over traditional urine tests. This preference is due to the extended detection timeline offered by hair tests—up to 90 days—collected under supervision with minimal risk of tampering. For detecting very recent drug use within five days, urine tests remain most accurate.

Hair analysis has gained recognition as a potent method for identifying drug and alcohol consumption. By embedding biomarkers within the fibers of growing hair strands, hair offers a prolonged account of alcohol and drug presence. When sampled near the scalp, hair provides a detection span of up to three months for alcohol and substances. It's straightforward to gather, challenging to tamper with, and simple to transport.
A hair sample of 1.5 inches consisting of around 200 strands (analogous to a #2 pencil's width) near the scalp produces 100mg, deemed an optimal sample for both screening and validation. For EtG, supplementary, and/or tests exceeding 10 panels, a collection of 150mg is advisable. Utilize a jeweler’s scale to weigh the specimen. If head hair isn’t attainable, an equivalent quantity of body hair can be used. "Head hair" specifically denotes scalp hair. "Body hair" includes all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test outcome involves four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning embodies the primary processing of a specimen into the lab's system. This phase consists of confirming proper sealing and shipment of the sample, allocating a random LAN (Laboratory Accessioning Number), and filling in any absent data not available through an electronic chain of custody system.
Screening entails an initial rapid assessment for substances of abuse. While Screening effectively rules out drug consumption in most samples, a positive screen demands verification for legal admissibility. Samples that are presumptively positive during Screening necessitate further confirmation.
If Screening shows a presumptive positive, additional hair is sourced from the original sample for Extraction. During Extraction, drugs are isolated from hair at notably lower concentrations than other techniques (such as urine or oral fluid), rendering hair drug screening the most intricate technique to execute.
Confirmation of any positive screen results is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, every presumptively positive sample undergoes cleansing as required. The entire cycle from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 quality standards.

Note: Commonly termed as "hair follicle tests", the examination actually assesses the hair strand rather than the follicle beneath the scalp.
