Hair analysis has gained recognition as an influential method for identifying drug and alcohol consumption. It offers a prolonged history of alcohol and drugs by encapsulating biomarkers within the fibers of the growing hair strand. When clipped close to the scalp, it can provide an approximate 3-month detection window for alcohol and other drugs. Collecting hair is straightforward, relatively resistant to tampering, and easy to transport.
A sample of 1.5-inch comprising roughly 200 hair strands (comparable to a #2 pencil) near the scalp will yield 100mg of hair, which is the optimal amount for initial testing and confirmation. For EtG, additional tests, and/or more than 10 panels, 150mg of the sample is advisable. Using a jeweler’s scale to weigh the sample is suggested. In the absence of scalp hair, a matching amount of body hair can be gathered. "Head hair" specifically denotes scalp hair. "Body hair" includes other hair types like facial or axillary hair.
Process Overview
The laboratory drug test result processing involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step of integrating a sample into a laboratory’s system. This process verifies the proper sealing and shipment of the sample, allocates a random LAN (Laboratory Accessioning Number), and completes any supplemental data entry not covered by an electronic chain of custody.
Screening constitutes an initial, swift assessment for drugs of abuse. While it serves as a cost-effective method to exclude drug usage for the majority of samples, a confirmation is necessary for a positive screen to hold up in court. Samples that are presumptively positive in Screening require a secondary confirmation.
Should a sample show a presumptive positive at the Screening stage, additional hair is extracted from the initial sample and readied for Extraction. During Extraction, drugs are isolated from hair in much lower concentrations than in other methodologies (such as urine or oral fluid), which makes hair drug screening one of the most challenging methodologies to conduct.
Positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleaned prior to confirmation as deemed necessary. The entire laboratory procedure from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
