Observing drug and alcohol consumption through hair testing is increasingly considered an effective technique. Hair captures a comprehensive timeline of alcohol and other drug usage by embedding biomarkers within its growing strands. Hair cut close to the scalp can offer a detection period up to about 3 months for alcohol and various drugs. Its collection is straightforward, making adulteration challenging, and easy to send.
A 1.5-inch section of roughly 200 hair strands, comparable in diameter to a #2 pencil, taken nearest the scalp, equates to 100mg, which is optimal for screening and definitive analysis. For EtG, additional requirements, and/or evaluations exceeding 10 panels, 150mg is advisable. It's suggested to weigh the sample using a jeweler's scale. If scalp hair is not present, a similar quantity of body hair is acceptable. "Head hair" pertains only to scalp hair, while "body hair" includes all other types (facial, axillary, etc.).
Process Overview
The key phases in processing a drug test in a lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the sample's entry into the lab system, confirming proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry absent from an electronic custody chain.
Screening serves as a preliminary check for abuse drugs. While a cost-efficient method to eliminate drug usage in most samples, a positive screen necessitates confirmation for legal admissibility. Presumptively positive samples in Screening require additional verification.
Should a sample be presumptively positive during Screening, more hair is extracted from the initial specimen for Extraction. Drugs are isolated from hair at significantly reduced concentrations compared to other methodologies (e.g., urine or oral fluid), making hair drug analysis the most complex method to execute.
Positive screening confirmations utilize GC/MS, GC/MS/MS, or LC/MS/MS techniques. Any presumptive positives are washed before confirmation as necessary. The comprehensive lab procedure from Accessioning to Confirmation undergoes scrutiny for both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
