Hair testing is now regarded as a significant technique for identifying drug and alcohol consumption. Hair captures a long-term record of alcohol and other drugs by embedding biomarkers in the strands of the growing hair. When collected near the scalp, hair can show a detection window of up to around 3 months for alcohol and other drugs. Hair is easy to collect, quite resistant to tampering, and convenient to transport.
A sample measuring 1.5 inches with roughly 200 hair strands (approximately the thickness of a #2 pencil) closest to the scalp yields 100mg of hair, which is the preferred amount for screening and confirmation. For EtG, additional tests, and/or panels beyond 10, 150mg of the sample is advised. It is suggested to weigh the sample on a jeweler's scale. If scalp hair is unavailable, a comparable quantity of body hair can be gathered. By head hair, we mean only scalp hair. Body hair includes any other hair types (facial, axillary, etc.).
Process Overview
The four essential stages in the laboratory handling of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial entry of a sample into a laboratory’s system. This entails confirming that the sample was appropriately sealed and shipped, assigning an arbitrary LAN (Laboratory Accessioning Number), and finishing any required data input not included by an electronic chain of custody system.
Screening refers to an initial rapid assessment for drugs of abuse. While Screening is a cost-efficient method to exclude drug usage in most samples, a positive screen necessitates confirmation to be acceptable in court. Any samples that suggest positive results in Screening mandate a secondary confirmation.
If a sample potentially shows positive in the Screening stage, further hair is taken from the initial sample and readied for Extraction. Here, drugs are extracted from hair at noticeably lower concentrations than in other methodologies (e.g., urine or oral fluid), elucidating why hair drug screening is the most complex method to execute.
Any confirmed screen positives undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. All potentially positive samples undergo washing as needed before confirmation. The complete laboratory procedure from Accessioning to Confirmation is appraised under both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.
