The use of hair testing is increasingly acknowledged as a potent means for detecting drug and alcohol consumption. Hair strands capture long-term evidence of substance use by embedding biomarkers within their fibers during growth. When hair is sampled close to the scalp, it can yield a detection period of up to approximately three months for drugs and alcohol. The collection process is straightforward, the sample is relatively resistant to tampering, and it can be easily transported.
A hair sample measuring 1.5 inches, consisting of around 200 strands (comparable to the width of a #2 pencil) near the scalp, amounts to 100mg—ideal for both screening and confirmation. For EtG, additional testing, or analyses above ten panels, a specimen of 150mg is preferred. It's advisable to measure the sample's weight using a jeweler’s scale. If scalp hair cannot be collected, an equivalent amount of body hair may serve as a substitute. In the context of head hair, only scalp hair is considered, whereas body hair encompasses all other types (such as facial and axillary hair).
Process Overview
The laboratory processing of drug test results comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial incorporation of a sample into the laboratory system, ensuring that the sample was properly sealed and dispatched, assigning a Laboratory Accessioning Number (LAN) at random, and completing any additional data entry outside of an electronic chain of custody system.
Screening involves an initial rapid assessment for substance abuse. Although Screening is a cost-efficient approach to eliminate drug use in most samples, a positive result requires confirmation to be legally acceptable. Samples that are presumptively positive during Screening necessitate a subsequent confirmation.
Should a sample prove presumptively positive at Screening, additional hair is extracted from the original specimen for the Extraction phase. During this stage, drugs are isolated from hair at significantly lower concentrations compared to other techniques (such as urine or oral fluid), contributing to the complexity of hair drug screening.
Confirmation of positive screening results is conducted by employing GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positive samples undergo washing prior to confirmation if required. The comprehensive laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair certification and compliance with ISO / IEC 17025 standards.
