Hair analysis has emerged as an effective method in detecting drug and alcohol consumption. The fibers of the growing hair strand capture biomarkers, offering a long-term record of alcohol and other drugs. Hair samples collected close to the scalp can reveal up to a 3-month history of alcohol and other drugs. Gathering hair is uncomplicated, hard to tamper with, and convenient to transport.
A sample of 1.5 inches comprising roughly 200 strands of hair—the thickness of a #2 pencil—from the scalp will yield 100mg, the perfect amount for testing and confirmation. For EtG, additional tests, or when exceeding 10 panels, 150mg of hair is suggested. It is advisable to use a jeweler’s scale to weigh the sample. In the absence of scalp hair, a similar quantity of body hair may be collected. "Head hair" pertains exclusively to scalp hair, whereas "body hair" covers all other kinds (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result is structured into four main steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial incorporation of a sample into a lab’s system. This process includes verifying that the sample was correctly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data entry not covered by an electronic chain of custody system.
Screening is a swift initial assessment for drugs of abuse. While it is a cost-efficient method to eliminate drug use in most samples, a positive result in Screening must be validated for court admissibility. Samples showing a positive indication in Screening require further confirmation.
When Screening indicates a presumptive positive, additional hair is extracted from the original sample for the Extraction phase. Here, drugs are isolated from hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening particularly challenging.
Any positive result from Screening is verified via GC/MS, GC/MS/MS, or LC/MS/MS. All samples that return a presumptive positive are cleansed before confirmation, as needed. The complete laboratory process from Accessioning to Confirmation is scrutinized under CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 standards.
