Hair testing is now viewed as an influential method for identifying alcohol and drug use. Hair offers a comprehensive timeline of substance use by embedding biomarkers within the hair’s fibers. When obtained near the scalp, hair can reveal drug and alcohol use within a span of roughly three months. It is easy to collect, somewhat resistant to tampering, and simple to transport.
A 1.5-inch segment of roughly 200 hair strands (approximately the size of a #2 pencil) closest to the scalp equals 100mg of hair, which is the optimal sample for testing and verification. For EtG, additional tests, or panels exceeding 10, a specimen weight of 150mg is advisable. Utilizing a jeweler’s scale for specimen weighing is suggested. Should scalp hair be inaccessible, an equivalent measure of body hair may be obtained. References to head hair pertain solely to scalp hair. Body hair encompasses all other hair types (such as facial, axillary, etc.).
Process Overview
The primary stages in the laboratory evaluation of a drug test are Accessioning, Screening, Extraction, and Confirmation.
Accessioning manages the initial entry of a sample into a lab’s database. This step confirms the sample’s proper sealing and shipment, assigns a random LAN (Laboratory Accessioning Number), and fulfills any other necessary data entry not captured by an electronic custody system.
Screening performs a preliminary check for drug presence. While this is a financially smart technique for negating drug use in most samples, a positive result must be verified to be court-accepted. Samples that appear positive in Screening need further confirmation.
Should a sample show a presumptive positive during Screening, additional hair is extracted from the original sample and readied for Extraction. Here, drugs are isolated from hair at concentrations lower than other methods (such as urine or oral fluid), making hair drug testing the most complex method to execute.
GC/MS, GC/MS/MS, or LC/MS/MS is used to confirm positive screenings. All samples indicating presumptive positives are cleansed before confirmation if necessary. The entire laboratory process, from Accessioning to Confirmation, is assessed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
