Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair captures a long-term account of substances, encapsulating markers within the hair's developing fibers. Samples acquired near the scalp can present a detection period extending up to around three months for alcohol and other substances. Hair is straightforward to gather, relatively tough to tamper with, and simple to transport.
A sample measuring 1.5 inches, consisting of roughly 200 hair strands (similar to a #2 pencil) nearest to the scalp, yields 100mg of hair, which is the optimal amount for both screening and confirmation. For EtG, additional substances, and/or tests exceeding 10 panels, it is advised to use 150mg of the sample. Utilizing a jeweler's scale for weighing the specimen is suggested. Should scalp hair be unavailable, a comparable quantity of body hair can be collected. In the context of head hair, this exclusively pertains to scalp hair. Body hair encompasses all other hair types (such as facial hair, axillary hair, etc.).
Process Overview
The laboratory processing of a drug test outcome involves four principal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary incorporation of a sample into a lab's system. This process includes checking that the sample was correctly sealed and shipped, attributing a random LAN (Laboratory Accessioning Number), and completing any necessary data entry absent in an electronic chain of custody system.
Screening acts as an initial rapid assessment for drugs of misuse. Although Screening provides a cost-efficient means of eliminating drug usage in a majority of samples, a positive screen must be confirmed for it to hold in court. Samples suspected to be positive in Screening mandate a secondary confirmation.
If a sample indicates presumptive positivity during the Screening phase, additional specimen hair is extracted and readied for Extraction. At this stage, drugs are withdrawn from hair at significantly lower concentrations than with other methods (e.g., urine or oral fluid), which makes hair drug screening the most challenging procedure to perform.
Verification of any positive screening outcome is done through GC/MS, GC/MS/MS, or LC/MS/MS. All specimens with presumptive positive outcomes are cleansed before confirmation, if necessary. The complete lab procedure from Accessioning to Confirmation undergoes assessment under the College of American Pathologists (CAP) Hair guidelines and in compliance with the ISO / IEC 17025 standards.
