Hair analysis is recognized as an effective approach for identifying drug and alcohol consumption. Hair captures a historical record of alcohol and other drugs by embedding biomarkers within the hair shaft as it grows. When taken near the scalp, hair samples offer a detection window of up to three months for alcohol and drugs. Hair collection is easy, not easily tampered with, and simple to transport.
A hair sample measuring 1.5 inches and containing roughly 200 strands (comparable to the thickness of a standard pencil) nearest the scalp results in 100mg of hair, which is the preferred amount for conducting screening and confirmation. For EtG, additional tests, or panels exceeding ten, 150mg is advisable. It's suggested to measure the hair on a jeweler’s scale. If scalp hair is unavailable, a comparable amount of body hair can be used. When we mention head hair, it refers exclusively to scalp hair. Body hair includes all other types (such as facial and underarm hair).
Process Overview
The major phases in laboratory processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves incorporating a sample into a lab’s system. This ensures the sample was correctly sealed and dispatched, assigns a unique LAN (Laboratory Accessioning Number), and completes any extra data input absent from an electronic custody chain system.
Screening is a preliminary check for drugs. This method is economical for eliminating drug use in most samples, but any positive screen must be verified for legal validity. Samples with a presumptive positive result during Screening demand verification.
Should a sample appear positive in Screening, additional hair is prepared for Extraction. Here, drugs are extracted from hair at a lower concentration compared to other techniques (e.g., urine or saliva), making hair drug screening more intricate.
Positive screening results are authenticated using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing prior to confirmation as needed. The comprehensive lab process from Accessioning to Confirmation is scrutinized under CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
