Hair testing is widely regarded as an effective method for identifying drug and alcohol consumption. This is because hair captures a prolonged history of substances by embedding biomarkers in the strands as they grow. When acquired close to the scalp, hair can reveal drug and alcohol usage for a period of nearly 3 months. The process of collecting hair is straightforward, relatively resistant to tampering, and convenient to transport.
A hair sample measuring 1.5 inches and comprising roughly 200 strands (akin to the size of a #2 pencil) nearest to the scalp provides 100mg, which is the perfect quantity for initial tests and confirmations. For EtG, additional tests, or panels exceeding 10, a specimen of 150mg is advisable. It's best to measure the specimen using a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair may be utilized. "Head hair" specifically refers to scalp hair, whereas "Body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory examination of a drug test sample involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially processed into the laboratory's system. This step confirms the sample was properly sealed and shipped, allocates a random Laboratory Accessioning Number (LAN), and executes any supplementary data entry absent from an electronic chain of custody system.
Screening provides a preliminary rapid assessment for substance abuse. Although Screening is an economical approach to dismiss drug usage in most samples, to be considered valid in legal proceedings, a positive result must be verified. Thus, any sample indicating a presumptive positive in Screening necessitates further confirmation.
Should the Screening stage suggest a presumptive positive, additional hair is extracted from the original specimen for the Extraction phase. Here, drugs are extracted from hair at significantly lower concentrations than other methods (such as urine or oral fluid), making hair drug testing the most challenging to conduct.
Positive results from Screening undergo Confirmation using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Samples with presumptive positive outcomes are cleansed before confirmation as necessary. The complete laboratory operation, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair classification and meets the ISO / IEC 17025 standards.
