Hair testing is now recognized as an effective method for identifying drug and alcohol consumption. By capturing biomarkers in the fibers, hair offers a prolonged record of alcohol and drugs within the growing strand. When taken near the scalp, hair can yield a detection period of up to three months for alcohol and other substances. Collection is straightforward, tampering is fairly challenging, and shipment is hassle-free.
A sample of 1.5 inches containing roughly 200 strands (equating to a #2 pencil's diameter) nearest the scalp yields 100mg of hair, an optimal amount for screening and confirming. For EtG, additional tests, and/or anything above 10 panels, 150mg of the sample is advisable. We suggest using a jeweler’s scale for measuring the specimen. If scalp hair is inaccessible, a comparable quantity of body hair might be collected. "Head hair" explicitly denotes scalp hair. "Body hair" covers all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes introducing the sample into the laboratory system, ensuring the sample's integrity via proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and fulfilling any supplementary data input not covered by an electronic chain of custody system.
Screening serves as an initial rapid assessment for substances misused. Though it offers a cost-effective approach for excluding drug use in most samples, a positive screen necessitates verification for court admissibility. Samples with presumption of positivity in Screening mandate a further confirmation.
In cases of presumptive positivity in the Screening phase, additional hair is extracted from the initial collection and readied for Extraction. In this process, substances are segregated from hair at significantly lower concentrations compared to other methods (like urine or oral fluid), making hair drug analysis the most intricate to execute.
Positive screening confirmations are performed via GC/MS, GC/MS/MS, or LC/MS/MS. Samples showing presumptive positivity undergo laundering before confirmation if needed. The entire chain from Accessioning to Confirmation is scrutinized under both CAP (College of American Pathologists) Hair guidelines and the ISO / IEC 17025 standards accreditation.
