Hair analysis has emerged as an effective method for identifying substance and alcohol usage. Hair retains a long-term record of alcohol and other substances by trapping biomarkers in the fibers of the growing hair shaft. When collected near the scalp, hair can offer a detection window of up to around three months for alcohol and other substances. Hair is uncomplicated to gather, relatively challenging to tamper with, and straightforward to transport.
A 1.5-inch section of approximately 200 hairs (roughly the dimension of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the preferred sample size for screening and verification. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the specimen is advised. We suggest weighing the specimen on a jeweler's scale. If scalp hair is not available, a comparable quantity of body hair can be collected. When discussing head hair, we are referring solely to scalp hair. Body hair includes all other hair types (facial, axillary, etc.).
Procedure Summary
The primary phases involved in the laboratory processing of a drug screen outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial handling of a sample within a laboratory's system. This process includes confirming that the sample was correctly sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and completing any further data entry absent in an electronic chain of custody system.
Screening consists of an initial rapid review for substances of abuse. Although Screening is an economical method to exclude drug use for the bulk of samples, a positive screen requires confirmation to be valid in legal proceedings. Any samples appearing positive in Screening necessitate a subsequent confirmation.
If a sample appears positive in the Screening phase, additional hair is extracted from the initial sample and prepared for Extraction. In this phase, substances are extracted from hair at a noticeably lower concentration than other methods (such as urine or oral fluids), which is why hair substance screening is considered the most challenging method to conduct.
Confirmation of any positive screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that preliminarily test positive undergo washing before confirmation if needed. The entire laboratory procedure from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 criteria.
