Seeing hair testing as an effective approach for identifying substance use, it provides a long-term profile of alcohol and drugs by embedding biomarkers in the fibers of the hair as it grows. When taken near to the scalp, hair can offer an approximately 90-day timeframe for alcohol and drug detection. Hair collection is straightforward, moderately resistant to tampering, and convenient for shipping.
A hair sample of 1.5 inches consisting of about 200 strands (approximately the width of a #2 pencil) nearest to the scalp yields 100mg, which is ideal for analysis and verification. For EtG, additional, and/or examinations exceeding 10 panels, 150mg of sample is advised. It's preferable to use a jeweler's scale for weighing the sample. If scalp hair isn't available, an equivalent volume of body hair may be taken. When discussing head hair, it pertains only to scalp hair. Body hair includes all other types (facial, axillary, etc.).
Process Overview
The processing of a laboratory drug test result involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a specimen into the laboratory’s system. This process involves verifying proper seal and shipment of the specimen, allocating a unique LAN (Laboratory Accessioning Number), and completing any manual data entry absent from the electronic chain of custody system.
Screening is an initial quick assessment for substance misuse. It is an affordable method to eliminate drug use in most cases, but a positive screen requires further confirmation for courtroom acceptance. Samples showing potential positives in Screening necessitate secondary verification.
In cases of presumed positivity during Screening, additional hair is extracted from the initial sample and readied for Extraction. This stage involves extracting drugs from hair at much lower concentrations compared to other tests (e.g., urine or oral fluid), highlighting why hair drug testing is among the most challenging methodologies to implement.
Confirmation for any positive Screening outcome uses GC/MS, GC/MS/MS, or LC/MS/MS. Before Confirmation, any potentially positive samples are cleansed as necessary. The comprehensive lab process from Accessioning to Confirmation is validated under CAP (College of American Pathologists) Hair designation and conforms to ISO / IEC 17025 accreditation standards.
