The utilization of hair analysis has emerged as an effective method for identifying the use of drugs and alcohol. Hair offers a prolonged timeline of substance usage by encapsulating biomarkers within the fibers of the hair as it grows. When extracted near the scalp, hair can reveal drug and alcohol usage for up to about a 3-month duration. Hair is straightforward to gather, less prone to tampering, and convenient to transport.
Collecting a 1.5-inch segment of roughly 200 hair strands (comparable to the thickness of a #2 pencil) closest to the scalp amounts to 100mg of hair, which is the optimal sample size for screening and verification. For EtG, additional tests, and/or assessments exceeding 10 panels, 150mg of the sample is advisable. It is suggested to measure the sample using a jeweler’s scale. In the absence of scalp hair, a corresponding quantity of body hair can be collected. "Head hair" specifically refers to scalp hair, while "body hair" encompasses all other types of hair (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test outcome involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary integration of a sample into the laboratory's framework. This involves confirming the proper sealing and dispatch of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing any further data entry absent from an electronic chain of custody system.
Screening consists of an initial rapid assessment for substances of abuse. Although Screening is an economical method to eliminate drug use in most samples, a positive screening necessitates validation to be legally defensible. Any samples that test presumptively positive in Screening require additional confirmation.
Should a sample yield a presumptively positive result during Screening, additional hair is retrieved from the initial sample and readied for Extraction. At this point, drugs are obtained from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), making hair drug screening the most challenging method to execute.
Comprehensive verification of any positive screening outcomes is conducted via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo cleansing before confirmation as required. The complete laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and accreditation by ISO / IEC 17025 norms.

Note: Commonly labeled as "hair follicle tests," the assessment itself examines the hair strand instead of the follicle beneath the scalp
