Hair testing is regarded as a significant method for detecting alcohol and drug consumption. Hair captures a long-term record of drug and alcohol intake by embedding biomarkers within the fibers of the hair strand as it grows. When collected near the scalp, hair can reveal drug and alcohol usage for up to a maximum of three months. Hair is straightforward to collect, tough to tamper with, and easy to transport.
A sample measuring 1.5 inches containing around 200 hair strands (roughly comparable to a #2 pencil's girth) near the scalp yields about 100mg of hair, which is the optimal sample size for screening and validation. For EtG, add-ons, and/or testing beyond 10 panels, a specimen size of 150mg is advised. It is recommended to weigh the hair sample on a jeweler’s scale. If scalp hair cannot be acquired, an equivalent amount of body hair can be used. The term head hair denotes scalp hair only. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The primary four steps of laboratory processing for a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary handling of a sample into a lab’s system. This step includes checking that the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary data entry not provided by an electronic chain of custody system.
Screening entails an initial swift check for abuse drugs. Although Screening serves as a cost-effective means to exclude drug consumption for most samples, a confirmed positive screen is necessary for court acceptance. Samples that are presumptive positives in Screening require secondary confirmation.
Should a sample show a presumptive positive in the Screening phase, additional hair is extracted from the original specimen and readied for Extraction. During Extraction, drugs are removed from hair at much lower concentrations than those used in other techniques (e.g., urine or oral fluid), making hair drug screening one of the most complex methodologies.
Confirmation of any positive screening outcome is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation if needed. The entire laboratory process, from Accessioning to Confirmation, is reviewed against both the CAP (College of American Pathologists) Hair designation and accreditation to the ISO / IEC 17025 standards.
