Hair analysis is increasingly recognized as a robust method for identifying drug and alcohol consumption. Hair strands offer an extended timeline of substance use, as they embed biomarkers within the hair as it grows. If clipped near the scalp, hair can reveal substance use for up to three months. Collection is straightforward, resisting tampering, and can be easily mailed.
A 1.5-inch section of about 200 hair strands, approximately the diameter of a #2 pencil, near the scalp, yields 100mg of hair, the preferred sample size for screening and verification. For EtG, additional tests, or panels above 10, a 150mg sample is suggested. It’s advisable to measure the sample with a jeweler’s scale. Should scalp hair be missing, an equal portion of body hair can be used. "Head hair" denotes scalp hair exclusively, while "body hair" refers to all other variants (facial, underarm, etc.).
Process Overview
The key stages in lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step where a sample enters the laboratory system. It involves confirming the sample was correctly sealed and transported, assigning a randomized LAN (Laboratory Accessioning Number), and filling in any extra data entry not covered by an electronic chain of custody system.
Screening is a preliminary check for drugs of abuse. While it’s an economical method to eliminate drug use for most samples, a positive screen must be confirmed for court admissibility. Any samples flagged as presumptively positive in Screening need additional confirmation.
Should a sample show a presumptive positive during the Screening stage, more hair is extracted from the original sample for the Extraction phase. Here, drugs are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening one of the more challenging methodologies to conduct.
All positive screen results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. Samples labeled as presumptive positives are cleansed before confirmation as required. The full laboratory workflow, from Accessioning to Confirmation, is examined under both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.
