Hair testing has emerged as a highly effective method for detecting drug and alcohol consumption. The hair captures long-lasting evidence of alcohol and other substances by embedding biomarkers within the fibers of the growing hair shaft. When collected near the scalp, hair can offer a detection window of up to roughly three months for both alcohol and drugs. The collection of hair is straightforward, challenging to tamper with, and convenient to transport.
A 1.5-inch sample comprising approximately 200 strands of hair (about the size of a #2 pencil) closest to the scalp will provide 100mg of hair, which is the optimum sample for testing and validation. For EtG, additional tests, and tests beyond 10 panels, it is advisable to collect 150mg of the sample. It's recommended to measure the sample using a jeweler’s scale. In the absence of scalp hair, a similar quantity of body hair can be used. When mentioned as head hair, it specifically refers to scalp hair. Body hair comprises all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result primarily consists of four stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary processing of a sample into the laboratory's system. This step includes checking that the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry that an electronic chain of custody system did not provide.
Screening performs an initial rapid assessment for drugs of abuse. While Screening is a cost-efficient method to exclude drug usage in the majority of samples, a positive screening result must be confirmed to be valid in legal proceedings. Any presumptive positive samples detected during Screening need further confirmation.
If a sample results as presumptive positive during the Screening phase, more hair is obtained from the original sample and prepared for Extraction. In this stage, drugs are extracted from hair at considerably lower concentrations than in other methodologies (i.e., urine or oral fluid), which makes hair drug testing the most complex methodology to execute.
Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are subjected to a wash before confirmation when necessary. The complete laboratory procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the accreditation per ISO / IEC 17025 standards.
