Hair analysis is recognized as an effective method for identifying drug and alcohol usage. Hair retains a long-term record of substance intake by embedding biomarkers within the strands as they grow. When collected close to the scalp, hair provides a detection period for substances, including alcohol, of up to three months. Hair collection is straightforward, relatively resistant to tampering, and easily transportable.
A sample measuring around 1.5 inches and consisting of roughly 200 hair strands (approximately pencil-width) from near the scalp yields 100mg — the preferred amount for both an initial screen and confirmation. For tests like EtG, additional testing, or those exceeding 10 panels, 150mg is advisable. It's best to weigh the sample with a jeweler’s scale. Should scalp hair not be available, an equivalent portion of body hair can be used. When mentioning head hair, it implies scalp hair specifically. Body hair includes all other kinds (facial, axillary, etc.).
Process Overview
In processing a drug test in a laboratory, the key stages are Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial integration of a sample into the lab system. This step verifies proper sealing and shipment, assigns a unique LAN (Laboratory Accessioning Number), and addresses any data entry not included in an electronic custody system.
Screening serves as a preliminary check for drug presence. Although Screening is a cost-efficient method to dismiss drug presence in most samples, a positive result necessitates confirmation if used in legal settings. Samples flagged as potentially positive through Screening require further confirmation.
When a sample shows a presumptive positive in Screening, more hair is extracted and prepared for the Extraction stage. Here, substances are drawn from hair at much lower concentrations than other methods (e.g., urine or saliva), marking hair drug screening as especially complex.
Confirmation of a positive Screening outcome involves GC/MS, GC/MS/MS, or LC/MS/MS. All samples with a presumptive positive are cleaned as required for verification. Each step from Accessioning to Confirmation is reviewed under CAP (College of American Pathologists) Hair designation along with ISO/IEC 17025 accreditation standards.
