Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. Hair retains a long-term record of substance use by embedding biomarkers within the growing filament. When sampled near the scalp, hair offers a detection window of roughly 90 days for both alcohol and drugs. Collecting hair is straightforward, hard to tamper with, and easy to transport.
A 1.5-inch section consisting of about 200 hairs (roughly the thickness of a #2 pencil) nearest the scalp yields 100mg of hair, the preferred specimen for analysis. For EtG, supplements, and/or tests exceeding 10 panels, 150mg of hair is advisable. It's suggested to measure the sample using a jeweler’s scale. If scalp hair isn’t available, a similar amount of body hair can be used. References to head hair are exclusively about scalp hair. Body hair includes other types of hair (facial, axillary, etc.).
Process Overview
There are four key phases in the lab analysis of a drug test which are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary processing of a sample within the lab’s system. This step verifies proper sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and completes additional data entry absent in an electronic chain of custody system.
Screening conducts a rapid preliminary test for drugs. Although Screening is cost-efficient to exclude drug usage in the majority of samples, a positive result must be verified for legal purposes. Samples suspected to be positive in Screening must undergo further confirmation.
Should a sample test positive during Screening, additional hair is retrieved from the original sample and readied for Extraction. This phase involves extracting drugs from hair at significantly lower concentrations than other techniques (e.g., urine or oral fluid), rendering hair drug analysis the most challenging technique to execute.
Positive screening results must be confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation as necessary. The entire process—from Accessioning to Confirmation—is audited according to both the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.
