Hair testing is now recognized as a potent method for detecting drug and alcohol usage. Hair strands retain a long-term record of biomarkers associated with alcohol and drugs as they grow. When collected close to the scalp, hair offers a detection window of up to approximately three months for both alcohol and drugs. Hair is easy to collect, somewhat difficult to tamper with, and convenient to ship.
A sample measuring 1.5 inches in length and consisting of approximately 200 strands (about the size of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is ideal for both screening and confirmation tests. For EtG, enhanced tests, and/or analyses exceeding 10 panels, a specimen of 150mg is preferred. Using a jeweler’s scale to weigh the sample is advisable. If scalp hair isn't accessible, an equivalent amount of body hair may be collected. References to head hair pertain exclusively to scalp hair, whereas body hair includes all other types (such as facial and axillary).
Process Overview
The primary steps involved in lab processing of drug test results are Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially processed into the laboratory's system, which includes verifying that the sample was appropriately sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing additional data entry not supplied by an electronic chain of custody system.
Screening involves a preliminary check for drugs of abuse. Though Screening is a cost-effective method to rule out drug use in most samples, a positive result requires confirmation to be acceptable in legal proceedings. Samples that test positive in the Screening stage need a secondary confirmation.
If a sample tests positive in the Screening phase, additional hair is extracted from the original sample for the Extraction phase. This phase involves extracting drugs from hair at significantly lower concentrations than in other methods (such as urine or oral fluid), making hair drug testing exceptionally challenging.
Confirmation of positive screening results is carried out using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positive results are washed before confirmation if necessary. The whole lab process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair program and ISO/IEC 17025 accreditation standards.

Limitations:
Note: While commonly called "hair follicle tests," the analysis is conducted on the hair strand, not the follicle beneath the scalp.
