Hair testing is regarded as an effective method for identifying drug and alcohol consumption. It allows for the long-term monitoring of substance use by capturing biomarkers in the fibers of growing hair strands. When hair is sampled near the scalp, it offers a detection period of up to around three months for alcohol and other substances. It is simple to collect, relatively resistant to tampering, and uncomplicated to transport.
A sample measuring 1.5 inches composed of approximately 200 hair strands (comparable to the thickness of a #2 pencil) taken closest to the scalp yields 100mg of hair, the perfect sample size for screening and confirmation. For EtG, additional testing, and/or panels exceeding 10 tests, a specimen weight of 150mg is advisable. It's recommended to use a jeweler’s scale for weighing. If scalp hair cannot be accessed, an equivalent quantity of body hair may be collected. By head hair, we specifically mean scalp hair. Body hair encompasses all other hair types (facial, axillary, and so on).
Process Overview
There are four pivotal stages in the laboratory's drug test processing: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the initial handling of a sample in a laboratory setup. This stage covers checking the sealing and delivery correctness, assigning a random LAN (Laboratory Accessioning Number), and finishing any extra data entry not covered by an electronic chain of custody protocol.
In the Screening phase, a rapid search is done for drugs of abuse. Though Screening is an economical way to dismiss drug use across many samples, any positive result necessitates confirmation for legal validity. Any samples identified as potentially positive in Screening must undergo further confirmation.
When a sample comes up as potentially positive during Screening, additional hair is extracted from the initial sample and readied for Extraction. At this stage, drugs are extracted from hair at lower concentrations than other methods (e.g., urine or oral fluid), thus making hair drug screening a more challenging methodology.
The Confirmation of any positive screen is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All provisional positive samples undergo a wash before confirmation if required. From Accessioning to Confirmation, the entire lab process complies with both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
