Hair assessments have emerged as an influential method for identifying alcohol and drug consumption. Hair strands secure a prolonged record of substance use by embedding biomarkers within the hair follicles as they grow. When clipped close to the scalp, hair can offer a detection span of up to three months for alcohol and various drugs. Collecting hair is straightforward, moderately resistant to tampering, and convenient for transportation.
A 1.5-inch segment comprising about 200 hair strands (comparable to the thickness of a #2 pencil) near the scalp yields around 100mg of hair, which is optimal for tests and verifications. For EtG, supplementary tests, or tests surpassing 10 panels, 150mg of the sample is suggested. The sample should ideally be weighed using a jeweler’s scale. If scalp hair is insufficient, a comparable quantity of body hair may be used. When mentioning head hair, we signify scalp hair exclusively. Body hair includes all other types (such as facial or axillary).
Process Overview
The laboratory processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the initial processing of a sample into a lab’s system occurs. This involves ensuring the sample was properly sealed and transmitted, assigning it a unique LAN (Laboratory Accessioning Number), and finishing any further data entry not handled by an electronic chain of custody system.
Screening entails an initial rapid check for substance abuse. Even though Screening is an economical means of ruling out drug use in most samples, a confirmed screen is necessary for legal admissibility. Any samples reacting positively in Screening require further confirmation.
If Screening suggests a positive result, additional hair is extracted from the original sample for the Extraction process. Here, drugs are isolated from hair at significantly lower levels than in other practices (such as urine or oral fluids), which renders hair drug screening as the most challenging method to execute.
The Confirmation of a positive screen utilizes GC/MS, GC/MS/MS, or LC/MS/MS. Before Confirmation, presumptive positive samples undergo washing as required. The full laboratory sequence from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair certification and ISO / IEC 17025 accreditation standards.

Limitations:
Note: Commonly called "hair follicle tests", these tests assess the hair strand itself, not the follicle beneath the scalp.
