Hair screening is now recognized as an effective method for identifying drug and alcohol use. Hair captures a long-term record of substances by embedding biomarkers within the strands as they grow. When gathered near the scalp, hair can offer up to a three-month detection window for substances. Its collection is straightforward, relatively tamper-proof, and easily transportable.
A 1.5-inch segment consisting of around 200 strands (approximately the width of a #2 pencil) nearest to the scalp provides a 100mg hair sample, optimal for screening and verification. For EtG, additional tests, and tests exceeding 10 panels, a specimen weighing 150mg is advisable. It's suggested to weigh the sample using a jeweler’s scale. If scalp hair is unavailable, a comparable amount of body hair may be used. "Head hair" refers to scalp hair alone, while "body hair" covers all other types (facial, axillary, etc.).
Process Overview
The primary phases in processing a drug test result in a laboratory are Accessioning, Screening, Extraction, and Confirmation.
Accessioning starts with incorporating a sample into the lab's system, confirming proper sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and completing any necessary data entry absent from an electronic chain of custody system.
Screening encompasses a preliminary check for substance abuse. Although it's a cost-efficient approach to rule out drug use in the majority of cases, a positive screen necessitates confirmation for legal admissibility. All presumptive positives in Screening need a further verification step.
Should a sample be presumptively positive during Screening, additional hair is taken from the initial sample for Extraction. This step removes drugs from hair at much lower levels than other methods (e.g., urine or oral fluid), making hair drug screening particularly challenging to conduct.
Confirmation of any positive screen uses GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives are cleansed before confirmation as required. The whole laboratory process, from Accessioning to Confirmation, is audited under both the CAP (College of American Pathologists) Hair program and ISO / IEC 17025 standards.
