Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. By embedding biomarkers in the fibers of the growing hair, hair offers a long-term record of substance use. Hair samples collected close to the scalp can provide a detection window of up to about three months for alcohol and drugs. The collection process for hair is straightforward, not easily tampered with, and simple to transport.
A 1.5-inch sample comprising around 200 strands (comparable to a #2 pencil in thickness) near the scalp yields 100mg of hair, which is optimal for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a sample of 150mg is advised. Use a jeweler’s scale to weigh the specimen. If scalp hair is not available, the equivalent amount of body hair may be used. Head hair specifically refers to scalp hair, while body hair includes all other types of hair (such as facial and axillary).
Process Overview
The laboratory processing of a drug test result involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of processing a sample within a lab’s system. It involves ensuring the sample was correctly sealed and shipped, allocating a random LAN (Laboratory Accessioning Number), and completing any data entry tasks that an electronic chain of custody system hasn’t covered.
Screening is a preliminary analysis for drugs of abuse. While it is a cost-efficient approach to exclude drug usage in the majority of cases, a positive screen requires confirmation for legal acceptability. Presumptively positive samples in Screening necessitate a secondary confirmation.
When a sample shows presumptive positivity in the Screening phase, additional hair is extracted from the initial sample and processed for Extraction. In this phase, drugs are extracted from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug testing the most complex methodology.
Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are washed before confirmation, as necessary. The complete lab process, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
