Hair analyses have emerged as an effective means for detecting drug and alcohol usage. Hair offers a comprehensive timeline of alcohol and drug intake, capturing biomarkers in the hair shaft as it grows. When taken from the area near the scalp, a hair sample can reveal drug and alcohol presence over a period of roughly 3 months. Hair collection is straightforward, difficult to tamper with, and convenient for transport.
A 1.5-inch lock of roughly 200 hair strands (comparable to a #2 pencil thickness) nearest the scalp provides around 100mg, which is the optimal quantity for initial screenings and verification. For EtG, more detailed tests, or panels exceeding 10, a 150mg specimen is advised. We suggest using a jeweler’s scale for precise weighing. If scalp hair isn't available, an equivalent volume of body hair can be utilized. References to head hair specifically denote scalp hair. Meanwhile, body hair encompasses all other hair forms (such as facial and axillary hair).
Process Overview
The critical stages in laboratory drug test processing are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves introducing a sample into the lab's system. This process includes checking the sample’s seal and shipping integrity, allocating a random LAN (Laboratory Accessioning Number), and inputting any additional data absent from the electronic chain of custody.
Screening constitutes an initial swift examination for substances of abuse. Although cost-effective for eliminating drug use in most samples, a positive result must be validated to serve as court evidence. All samples with a presumptive positive result in Screening require further confirmation.
Should a specimen yield a presumptive positive at the Screening phase, more hair is prepared from the original sample for Extraction. During this phase, drugs are separated from the hair at significantly lower concentrations compared to other methods (e.g., urine or saliva), positioning hair analysis as the most challenging form of drug screening.
Positive Screening results are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. Before proceeding to confirmation, presumptive positives are cleaned as necessary. The entire process from Accessioning to Confirmation undergoes evaluation according to CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation standards.
