Hair testing is now recognized as an efficient method for identifying substance use. Hair fibers preserve a lasting record of drug and alcohol use by embedding biomarkers within the strand as it grows. When hair is gathered near the scalp, it can show a drug and alcohol use history of up to roughly 3 months. The collection process is straightforward, resistant to tampering, and easy to transport.
A sample measuring 1.5 inches in length, consisting of about 200 hairs (approximating the thickness of a #2 pencil) and nearest to the scalp, provides 100mg, ideal for analysis. For EtG testing, additional tests, and panels over 10, a specimen weight of 150mg is advised. Using a jeweler’s scale for weighing the specimen is suggested. If scalp hair cannot be obtained, equivalent body hair may be used. "Head hair" refers exclusively to scalp hair, while "Body hair" encompasses all other hair types (facial, axillary, etc.).
Process Overview
The lab procedures for drug test analysis include Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial sample registration in a laboratory system. This step ensures the sample is properly sealed and dispatched, assigns a LAN (Laboratory Accessioning Number), and fills in any missing information not recorded by electronic means.
Screening involves conducting a basic test for drugs. Though cost-effective and efficient for most cases, a positive screen requires further validation for legal evidence. Positive Screening needs a secondary Confirmation.
If Screening results are positive, additional hair from the initial sample is readied for Extraction. Drugs are extracted from hair at much lower levels compared to other methods (e.g., urine or oral fluid), thus making hair testing the most intricate procedure.
Positive Screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Samples that screen positive undergo a wash before Confirmation if necessary. The lab process, from Accessioning to Confirmation, is reviewed per the CAP (College of American Pathologists) Hair criteria and ISO/IEC 17025 accreditation.
