Hair testing has become recognized as a robust method for identifying drug and alcohol usage. Hair captures a comprehensive history of alcohol and other substances by embedding biomarkers in the developing hair fibers. Collected near the scalp, hair can reveal up to a 3-month detection period for alcohol and other substances. Hair collection is straightforward, challenging to tamper with, and simple to transport.
A 1.5-inch segment, roughly 200 strands of hair (comparable to the thickness of a #2 pencil) closest to the scalp provides 100mg, which is the optimal amount for screening and confirmation. For EtG, additional tests, or panels exceeding 10, a 150mg specimen is advised. It's suggested to measure the sample using a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair can be acquired. Scalp hair refers exclusively to the hair on the head. All other hair types (facial, axillary, etc.) are categorized as body hair.
Process Overview
The primary steps in processing a drug test in a laboratory are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a specimen into the laboratory’s system. This involves ensuring the sample was correctly sealed and delivered, assigning a random LAN (Laboratory Accessioning Number), and completing any additional information entry not included by an electronic chain of custody.
Screening consists of a preliminary quick test for substance abuse. While Screening is an economical method to exclude drug use on most samples, a positive result must be verified to be court-admissible. Any samples with a presumptive positive result in Screening require further confirmation.
Should a specimen show a presumptive positive in the Screening phase, additional hair is drawn from the primary sample and readied for Extraction. During this step, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging method to perform.
Confirmation of any positive screening is executed via GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples are cleansed before confirmation as necessary. The complete laboratory procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
