Recognized as an effective means for identifying substance use, hair testing captures drug and alcohol use through biomarkers embedded in the strands as they grow. When hair is sampled near the scalp, it offers an approximately 90-day detection period for both alcohol and other drugs. The process of collection is straightforward, challenging to tamper with, and simple to transport.
A 1.5-inch portion comprising around 200 hair strands (comparable to a #2 pencil in thickness) taken from nearest the scalp yields about 100mg of hair, which is ideal for analysis. For EtG, add-on tests, or panels exceeding 10, a 150mg specimen is advisable. Using a jeweler's scale for weighing is recommended. If scalp hair is not available, a similar quantity of body hair is an alternative. "Head hair" refers solely to scalp hair, whereas "body hair" encompasses other forms like facial and axillary hair.
Process Overview
The four core phases encompassing the laboratory processing of drug testing include Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial handling of a specimen as it is recorded into a laboratory's process. This involves ensuring the sample was properly sealed and transmitted, allocating it a random LAN (Laboratory Accessioning Number), and completing data requirements absent in an electronic chain of custody setup.
Screening serves as a preliminary evaluation for substance abuse. Although it effectively rules out drug presence in most samples affordably, a positive result necessitates confirmatory testing for legal acceptability. Samples yielding presumptive positives in Screening require further validation.
For samples indicating a presumptive positive during Screening, further extraction of hair from the initial collection is performed. In this stage, the concentrations of drugs extracted from hair are remarkably lower compared to other techniques (such as urine or oral fluids), underlining the complexity inherent in hair drug screening procedures.
Positive screening results undergo Confirmation through methods like GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed before confirmation when necessary. Laboratory processes from Accessioning to Confirmation undergo verification by both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standard accreditation.
