Hair testing is increasingly recognized as a robust method for identifying drug and alcohol consumption. Hair records an extended timeline of alcohol and drug use by securing biomarkers within the strands during growth. Collected near the scalp, hair can provide an approximate three-month period detection window for substances. Collection of hair is straightforward, relatively tough to tamper with, and convenient to transport.
A 1.5-inch segment of around 200 hair strands (comparable to the girth of a #2 pencil) adjacent to the scalp provides 100mg, which is optimal for examination and verification. For EtG, additional screenings, and/or tests exceeding 10 panels, a 150mg sample is advisable. We recommend measuring the specimen on a jeweler’s scale. In instances where scalp hair is absent, an equivalent quantity of body hair can be obtained. In our context, head hair refers exclusively to scalp hair, whereas body hair denotes other types (facial, axillary, etc.).
Process Overview
The key procedures in laboratory analysis of a drug test result comprise Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a sample within a laboratory system. This involves confirming proper sealing and shipment of the sample, assigning an arbitrary LAN (Laboratory Accessioning Number), and finalizing additional data entry absent from an electronic chain of custody system.
Screening is a primary method for identifying drugs of misuse. While screening serves as an economical approach for ruling out drug use in numerous samples, a positive outcome in screening necessitates confirmation for legal standing. All samples preliminarily positive in Screening require further confirmation.
Should a sample yield a potential positive during Screening, more hair is retrieved from the original specimen for Extraction. During Extraction, drugs are separated from hair at much lower concentrations than other techniques (e.g., urine or oral fluid), rendering hair drug screening the most complex methodology.
Confirmation of any positive screening findings is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all suspected positive specimens are cleansed as necessary. The comprehensive laboratory procedure from Accessioning to Confirmation is scrutinized following both CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation standards.
