Hair analysis has gained recognition as an effective means for uncovering drug and alcohol consumption. Hair can capture a historical record of substance use by embedding biomarkers within the fibers of the hair strand as it grows. When obtained near the scalp, hair offers an approximate three-month detection timeframe for alcohol and drugs. Hair collection is straightforward, relatively tamper-resistant, and convenient to transport.
A sample measuring 1.5 inches with roughly 200 hair strands (comparable to a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal amount for both screening and confirmation. For EtG, add-ons, and tests exceeding 10 panels, a sample of 150mg is suggested. It's advisable to use a jeweler’s scale for specimen weighing. If scalp hair is not available, a similar quantity of body hair can be collected. "Head hair" pertains solely to scalp hair, while "body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
The key stages in laboratory handling of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a laboratory’s system. This step involves ensuring proper sealing and shipping of the sample, assigning it a unique LAN (Laboratory Accessioning Number), and finalizing any additional data input not covered by an electronic chain of custody process.
Screening offers a preliminary check for drug usage. Though Screening is a cost-efficient method to rule out drug use across most samples, any positive result from this stage requires confirmation for courtroom validity. Samples deemed presumptively positive in Screening mandate further confirmation.
In cases where Screening indicates a presumptive positive, additional hair is extracted from the original sample and prepared for Extraction. Here, drugs are retrieved from hair at lower concentrations than other approaches (e.g., urine, oral fluid), making hair drug screening the most challenging methodology to execute.
Any positive screening outcomes are verified through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive specimens undergo washing as necessary before confirmation. The comprehensive lab procedure from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and accreditation in accordance with ISO / IEC 17025 standards.
