Hair assessments are increasingly recognized as an effective means for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and drug markers within the fibers of the developing hair strand. When collected from the scalp area, hair offers an approximate detection range of up to three months for alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and simple to transport.
A sample of 1.5 inches, containing about 200 hair strands (akin to the thickness of a #2 pencil) nearest the scalp, yields 100mg of hair, the optimal sample size for both screening and confirmation processes. For EtG examinations, additional tests, or screenings exceeding 10 panels, a 150mg specimen is advised. It is recommended to weigh the sample on a jeweler’s scale. If scalp hair is unavailable, an equivalent amount of body hair can be used. When discussing head hair, we specifically mean scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The primary stages in laboratory drug test processing include Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, the sample undergoes initial processing into the lab system, which involves verifying the specimen’s seal and shipment, assigning a unique LAN (Laboratory Accessioning Number), and completing extra data entry if not provided by an electronic chain of custody system.
Screening entails a preliminary, rapid assessment for substance abuse. Although Screening is cost-efficient for excluding drug use in most samples, positive screens require confirmation for legal admissibility. Samples that test presumptively positive during Screening necessitate secondary confirmation.
When a sample shows presumptive positivity in Screening, additional hair is extracted from the initial sample for the Extraction phase. This phase involves extracting drugs from hair at a concentration noticeably lower than in other methods (for instance, urine or oral fluid), making hair drug screening the most intricate method.
Confirmation of any positive Screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positives are cleansed as necessary before confirmation. The whole lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation standards of ISO / IEC 17025.
