Hair analysis is regarded as an effective method for identifying drug and alcohol consumption. The fibers of growing hair strands encase biomarkers, offering an extensive record of substance use. When hair is cut close to the scalp, it can reveal substance use for up to a three-month period. Hair collection is straightforward, challenging to tamper with, and convenient to transport.
A sample measuring 1.5 inches and consisting of roughly 200 hair strands (similar in size to a #2 pencil) taken nearest to the scalp yields 100mg of hair, which is optimal for screening and confirmation purposes. For EtG, add-ons, and tests beyond 10 panels, a specimen of 150mg is advised. Using a jeweler’s scale to weigh the specimen is recommended. If scalp hair can’t be accessed, the same amount of body hair may be used. The term head hair specifically denotes scalp hair. Body hair pertains to all other types, including facial and axillary hair.
Process Overview
The laboratory analysis of a drug test entails four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary process that enters a sample into the lab's system. This step checks the seal and shipment of the sample, assigns a randomized LAN (Laboratory Accessioning Number), and completes any extra data input not covered by the electronic chain of custody system.
Screening is a rapid initial test for substances of abuse. Although Screening offers a cost-efficient way to exclude drug use in most samples, a positive screen needs confirming to be valid for legal purposes. Samples that yield a presumptive positive result in Screening require a secondary Confirmation.
In cases of presumptive positive findings during Screening, additional hair is extracted from the initial sample and readied for Extraction. During Extraction, drugs are withdrawn from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), which is why hair drug analysis presents the most challenging execution.
Confirmation of positive screening outcomes is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. Any samples labeled presumptive positive undergo washing before Confirmation, as necessary. The complete laboratory protocol from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair guidelines and accreditation to ISO / IEC 17025 criteria.
