Hair analysis has emerged as a vital instrument for identifying drug and alcohol consumption. Hair strands capture biomarkers in their fibers, which provide a long-term record of alcohol and drug usage. When sampled near the scalp, hair offers a detection window of up to about three months for alcohol and drug use. It is easy to collect, relatively tough to manipulate, and straightforward to transport.
A 1.5-inch segment of roughly 200 hair strands (comparable to the diameter of a #2 pencil) taken nearest the scalp provides 100mg of hair, an optimal amount for both screening and confirmation. For EtG testing, additional screenings, and/or panels beyond ten, a 150mg sample is advisable. We suggest using a jeweler’s scale for weighing the sample. If hair from the scalp is not available, a comparable quantity of body hair can be used. The term head hair exclusively refers to scalp hair. In contrast, body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The key steps in lab processing for drug testing include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial intake of a sample into the laboratory’s database. It entails ensuring proper sealing and shipping of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data entry not covered by an electronic chain of custody system.
Screening entails a rapid assessment for potential drug presence. Though cost-effective for excluding drug use in most samples, a positive result in screening must be confirmed for legal acceptability. Samples showing presumptive positives in Screening must undergo secondary confirmation.
If Screening yields a presumptive positive, additional hair is extracted from the original sample for Extraction. At this stage, drugs are extracted from hair in much lower concentrations than in other testing methods (such as urine or oral fluid), which makes hair drug screening particularly challenging.
Confirmation of any positive screening result is conducted through GC/MS, GC/MS/MS, or LC/MS/MS methods. Prior to confirmation, all samples showing presumptive positives are cleaned as needed. The full laboratory journey from Accessioning to Confirmation is examined under the CAP (College of American Pathologists) Hair certification, along with ISO/IEC 17025 accreditation.
