Hair analysis has emerged as a robust method for identifying substance use. Hair captures a long-term profile of drug and alcohol consumption by trapping markers within the fibers of the hair as it grows. When taken from near the scalp, hair can reveal substance use for a detection window of up to three months. Collecting hair is straightforward, relatively hard to alter, and simple to transport.
A 1.5-inch section consisting of around 200 hair strands (approximately the width of a #2 pencil) nearest the scalp provides 100mg of hair, which is optimal for both screening and validation. For EtG, supplementary tests, and panels exceeding 10, 150mg of hair is advised. Using a jeweler’s scale to weigh the sample is suggested. If scalp hair isn't accessible, an equivalent portion of body hair can be used. When mentioning head hair, it denotes scalp hair specifically. Body hair includes all other types (facial, axillary, etc.).
Process Overview
The primary steps in the lab processing for drug test assessment include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into a laboratory's protocol. This process verifies proper sealing and shipment of the sample, assigns a Laboratory Accessioning Number (LAN), and completes supplementary data entry not covered by an electronic chain of custody system.
Screening is a preliminary rapid evaluation for substance abuse. Although Screening is an economical way to discount drug use in the bulk of samples, a positive outcome necessitates confirmation to be valid in a legal context. Any samples that presumptively test positive in Screening must undergo additional verification.
In cases where a sample tests presumptively positive during Screening, additional hair is obtained from the original sample and prepared for Extraction. Drugs in this phase are extracted from hair at lower concentrations compared to other methods (such as urine or oral fluid), thus making hair drug testing one of the most complex methodologies.
Positive screening results are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples are cleansed prior to confirmation as required. The entire process, from Accessioning to Confirmation, is reviewed under both the CAP (College of American Pathologists) Hair classification and accredited to ISO / IEC 17025 standards.
