Hair testing is now widely regarded as an effective instrument for identifying drug and alcohol consumption. Hair captures a prolonged history of alcohol and drug use by embedding biomarkers within the strands of the developing hair. If gathered from near the head, hair offers a detection period of about 3 months for alcohol and other substances. Hair collection is straightforward, challenging to tamper with, and simple to transport.
Obtaining a 1.5-inch segment of roughly 200 hair strands (similar in size to a #2 pencil) nearest to the scalp produces a 100mg hair specimen, optimal for both screening and verification. For EtG, supplemental measures, and/or testing exceeding 10 panels, a 150mg sample is recommended. It is advised to measure the specimen with a jeweler’s scale. In the absence of scalp hair, a comparable amount of body hair can be gathered. Note that head hair refers to scalp hair alone, while body hair encompasses all other types (e.g., facial, underarm, etc.).
Process Overview
The laboratory workflow for processing a drug test result encompasses Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the sample's initial integration into a lab's system, which includes confirming correct sealing and shipment, assigning a Laboratory Accessioning Number (LAN) randomly, and completing any missing data entry absent in an electronic chain of custody system.
Screening involves a preliminary rapid assessment for substance abuse. Although Screening offers a cost-effective means to eliminate drug use in most samples, a positive finding necessitates further validation to be court-admissible. Any samples returned as presumably positive in Screening demand secondary confirmation.
In cases of a presumptive positive at the Screening phase, additional hair is extracted from the original sample to prepare for Extraction. Here, drugs are isolated from the hair at a notably lower concentration than other techniques (like urine or saliva), making hair drug testing one of the most challenging methods to execute.
Validation of any positive screening outcome occurs through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing before confirmation, if needed. Every phase, from Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair designation as well as the ISO / IEC 17025 accreditation standards.

Limitations:
Note: Although commonly termed as "hair follicle tests", this test examines the hair strand and not the follicle beneath the scalp.
