Hair examinations have emerged as an effective instrument for identifying drug and alcohol consumption. Hair encapsulates long-term evidence of alcohol and drugs by embedding biomarkers within the strands of developing hair. When obtained near the scalp, hair can offer a detection period of up to roughly 3 months for substances such as alcohol and drugs. Hair is straightforward to gather, relatively hard to tamper with, and convenient to dispatch.
An inch-and-a-half sample containing approximately 200 strands of hair (similar in size to a #2 pencil) from just above the scalp provides 100mg of hair, which is the preferred amount for evaluation and confirmation. For EtG, additional options, and tests exceeding 10 panels, 150mg of hair is advised. For precise measurement, it’s suggested to use a jeweler’s scale. If scalp hair is not present, an equivalent amount of body hair can be used. References to head hair imply scalp hair exclusively. Body hair denotes all other hair types (such as facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test involves four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial entry of a sample into a laboratory’s framework, including validating that the sample was correctly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data collection absent from an electronic chain of custody system.
Screening indicates an initial rapid assessment for substances of abuse. Although Screening is a cost-efficient measure to negate drug use in most samples, a positive screening must be verified to hold up in a legal scenario. Samples that show presumptive positivity in Screening necessitate a secondary confirmation.
In the event a sample shows presumptive positivity during Screening, a larger portion of hair is extracted from the original sample and prepared for Extraction. During this stage, substances are extracted from hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), highlighting why hair drug screening poses the most challenges to execute.
Confirmation of any positive screening result is executed through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Each sample with presumptive positivity is cleansed prior to confirmation as required. The entire laboratory sequence from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
