Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. It offers a prolonged history of substance use through the capture of biomarkers within the hair strand as it grows. When cut near the scalp, hair can reveal a detection period of up to roughly three months for alcohol and drugs. Hair collection is straightforward, somewhat tamper-resistant, and conveniently transportable.
A strand length of 1.5 inches consisting of approximately 200 hairs (about the girth of a #2 pencil) taken nearest to the scalp will provide around 100mg, which is the optimal amount for initial screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, 150mg of hair is suggested. Using a jeweler's scale for measuring the sample is advisable. In cases where scalp hair is not present, a comparable quantity of body hair can be used. The term head hair specifically denotes scalp hair. All other hair types (such as facial or axillary hair) are considered body hair.
Process Overview
The primary laboratory procedures in processing drug test outcomes include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial assimilation of a sample into the laboratory's system. This procedure includes ensuring the sample's secure sealing and shipment, allocating a unique LAN (Laboratory Accessioning Number), and entering any additional data not included in an electronic chain of custody framework.
Screening involves a preliminary rapid evaluation for the presence of drugs. Although Screening is a cost-efficient approach to dismiss drug use in most samples, a screen with a positive result necessitates confirmation to be legally defensible. Samples indicating presumptive positives in Screening are obliged to undergo a subsequent confirmation.
Should a sample show a presumptive positive during the Screening phase, further hair is extracted from the original sample and prepped for Extraction. In this phase, substances are drawn from hair at significantly lower concentrations compared to other techniques (e.g., urine or oral fluid). Hence, hair drug testing is among the most intricate approaches to conduct.
Confirmation of a positive result from Screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that show presumptive positivity undergo washing prior to confirmation as necessary. The whole laboratory workflow from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair criteria and accreditation by ISO / IEC 17025 standards.
