Hair testing is now perceived as a robust method for detecting drug and alcohol consumption. Hair captures a prolonged record of drugs and alcohol by embedding biomarkers in the fibers of the developing hair strand. Once collected near the scalp, hair can offer up to roughly a 3-month detection timeframe for alcohol and drugs. The collection of hair is straightforward, somewhat hard to tamper with, and convenient to transport.
A 1.5-inch section of about 200 hair strands (approximately the size of a #2 pencil) closest to the scalp yields 100mg of hair, the optimal sample for screening and validation. For EtG, add-ons, and/or tests beyond 10 panels, 150mg of the specimen is suggested. It's recommended to weigh the sample on a jeweler's scale. In the absence of scalp hair, an equivalent quantity of body hair can be gathered. Referring to head hair implies scalp hair only. Body hair pertains to other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result comprises four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the sample's initial incorporation into a lab's system. This encompasses verifying that the sample was appropriately sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and completing any further data entry absent from an electronic chain of custody system.
Screening entails a primary swift evaluation for drug misuse. Although Screening is an economical method to exclude drug usage for most samples, a positive screen must be verified for court admissibility. Samples that are presumptively positive in Screening necessitate a secondary confirmation.
If a sample is presumptively positive during the Screening phase, additional hair is extracted from the initial specimen and prepped for Extraction. In this phase, drugs are extracted from hair at significantly lower concentrations than other methodologies (e.g., urine or oral fluid), underscoring hair drug screening's complexity.
Confirmation of any positive screening outcome is conducted via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples, prior to confirmation, are washed as necessary. The comprehensive laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation per ISO / IEC 17025 standards.
