The evaluation of hair has emerged as an effective technique in identifying the consumption of drugs and alcohol. Hair captures prolonged histories of alcohol and drug use by embedding biomarkers within the strands as they grow. When clipped near to the scalp, it can yield a detection period of up to around three months for both alcohol and drugs. The procedure of gathering hair is straightforward, not easily tampered with, and convenient to send.
A 1.5-inch section comprising approximately 200 strands of hair (roughly the width of a #2 pencil) nearest the scalp will provide 100mg of hair, which is considered the perfect amount for screening and validation. For EtG, additional tests, and/or examinations exceeding 10 panels, it’s advisable to collect 150mg of the hair specimen. Measuring the sample with a jeweler’s scale is advised. If hair from the scalp is not an option, the same amount from body hair can be used. By head hair, we mean scalp hair specifically. Body hair includes any other hair categories (facial, axillary, etc.).
Process Overview
The test result processing in the lab involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is about the sample's preliminary entry into a lab's system. This phase ensures that the sample's seal and shipment are intact, allocates a random LAN (Laboratory Accessioning Number), and completes any remaining data entry omitted by an electronic custody protocol.
Screening represents the initial quick assessment for substance misuse. Even though Screening is an affordable approach for ruling out drug use in most cases, a positive screening must be further confirmed for admissibility in judicial proceedings. Any sample indicating a presumptive positive during Screening needs a subsequent verification.
Upon getting a presumptive positive during the Screening phase, additional hair is extracted from the original sample for the Extraction stage. At this point, drugs are isolated from hair at notably lower concentrations than other methods (such as urine or oral fluid), hence making hair drug tests the most intricate to administer.
Verification of a positive screening outcome is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. Any samples preliminarily identified as positive are cleansed before confirmation if necessary. The complete lab process from Accessioning through Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and against the ISO / IEC 17025 accreditation criteria.
