Hair testing is increasingly recognized as an effective means to identify drug and alcohol consumption. Hair captures a prolonged history of substance use by embedding biomarkers within the growing hair fibers. When collected near the scalp, hair can reveal substance use over an approximately three-month period. Hair sampling is easy to perform, comparatively resistant to tampering, and straightforward to transport.
A 1.5-inch hair sample consisting of roughly 200 strands (approximately the thickness of a #2 pencil) from the scalp will yield 100mg of hair, the preferred amount for screening and confirmation. For tests including EtG, extensions, and/or more than 10 panels, 150mg of hair is suggested. It's advisable to use a jeweler’s scale to weigh the sample. If scalp hair is not available, an equivalent volume of body hair may be used. "Head hair" refers specifically to scalp hair, while "body hair" encompasses all other hair types (like facial or axillary hair).
Process Overview
The four primary stages in processing a drug test in the lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial integration of a sample into a lab’s system. This includes confirming the sample was properly sealed and dispatched, designating a random LAN (Laboratory Accessioning Number), and filling in any extra data not captured by an electronic chain of custody system.
Screening serves as an initial fast assessment for substances of abuse. Although Screening is a budget-friendly way to exclude drug usage in the bulk of samples, a positive screen must be verified to be legally valid. Any samples that are initially positive in Screening are subject to a secondary verification.
Should a sample be presumptive positive during Screening, additional hair is taken from the initial sample to prepare for Extraction. Here, substances are isolated from hair at much lower concentrations than in other methods (such as urine or oral fluid), which is why hair drug screening is one of the most challenging methodologies to execute.
Confirmation of any positive Screening outcome is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples preliminarily positive are cleansed before confirmation as necessary. From Accessioning to Confirmation, the complete laboratory procedure is examined under the CAP (College of American Pathologists) Hair designation and aligned with ISO/IEC 17025 standards.
