Hair testing has emerged as a potent method for identifying substance use involving drugs and alcohol. Hair retains a detailed historical record of alcohol and drug use by encasing biomarkers in the hair's developing fibers. When gathered near the scalp, hair can offer a detection period extending to roughly three months for drugs and alcohol. Hair is straightforward to collect, challenging to tamper with, and convenient to transport.
A hair sample measuring 1.5 inches, comprised of approximately 200 strands (comparable to the diameter of a #2 pencil) closest to the scalp, yields 100mg, which is the optimal amount for thorough screening and verification. For EtG, supplemental testing, and/or evaluations exceeding 10 panels, a 150mg specimen is advised. It's advisable to weigh the specimen with a jeweler’s scale. Should scalp hair be inaccessible, an equivalent quantity of body hair can be used. "Head hair" refers solely to scalp hair, while "body hair" encompasses all other hair varieties, including facial and axillary hair.
Process Overview
In the laboratory processing of a drug test result, there are four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the preliminary handling of a sample within a laboratory system. This process includes verifying proper sealing and shipment of the sample, allocating a random LAN (Laboratory Accessioning Number), and completing any additional data entry absent in an electronic chain of custody system.
Screening serves as a preliminary assessment for abuse substances. While an economical approach to negate drug use in most samples, a Screening-positive result requires confirmation to stand in legal proceedings. Samples flagged as presumptive positives in Screening necessitate further confirmation.
In cases where a sample tests presumptive positive during Screening, additional hair is extracted from the initial specimen and processed for Extraction. This phase involves extracting drugs from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), underpinning the complexity of hair drug screening compared to other methodologies.
Confirmation of a positive Screening result employs GC/MS, GC/MS/MS, or LC/MS/MS methodologies. Presumptive positive samples undergo washing before necessary confirmation. The comprehensive laboratory process, from Accessioning to Confirmation, undergoes review under the CAP (College of American Pathologists) Hair designation and aligns with ISO/IEC 17025 accreditation standards.
