The utilization of hair testing has emerged as a robust approach for identifying the consumption of drugs and alcohol. Hair captures a long-term record of alcohol and drug intake by securing biomarkers within the fibers of the maturing hair strand. When harvested near the scalp, hair can offer a detection period extending up to roughly three months for alcohol and narcotics. The collection process for hair is straightforward, challenging to tamper with, and convenient for transport.
A segment measuring 1.5 inches and comprising roughly 200 hair strands (comparable to the diameter of a #2 pencil) closest to the scalp provides 100mg of hair, which serves as the optimal quantity for both screening and confirmation. For EtG, supplementary tests, and/or evaluations involving more than 10 panels, a specimen volume of 150mg is advised. Utilizing a jeweler’s scale is recommended for weighing the specimen. In instances where scalp hair is not accessible, a comparable amount of body hair can be gathered. “Head hair†specifically pertains to scalp hair, whereas “body hair†encompasses all other varieties (such as facial and axillary hair).
Process Overview
The laboratory processing of a drug test result comprises four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the preliminary processing of a sample into a laboratory’s framework. This phase involves ensuring the sample was correctly sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and fulfilling any supplementary data entry absent from an electronic chain of custody framework.
Screening offers an initial swift assessment for substances of abuse. While cost-effective, Screening is primarily useful for clearing the majority of samples from suspicion of drug use; however, a positive screen necessitates confirmation for legal acceptability. Presumptive positives in Screening require additional confirmation.
Should a sample test positive in the Screening phase, additional hair is retrieved from the original specimen and readied for Extraction. Here, drugs are extracted from hair at concentrations significantly lower than in other testing methods (e.g., urine or oral fluid), underscoring the complexity of hair drug screening compared to other methodologies.
Confirmation of any positive screen result is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens undergo washing prior to confirmation. The comprehensive laboratory procedure, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation aligned with ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Commonly dubbed as "hair follicle tests", these tests actually analyze the hair strand rather than the follicle beneath the scalp.
