Hair examinations are increasingly recognized as an effective instrument for identifying drug and alcohol consumption. Hair acts as a prolonged archive of substance use by capturing biomarkers within the fibers of the advancing hair strand. When acquired near the scalp, hair can offer nearly a 3-month detection timeframe for alcohol and other substances. Hair is straightforward to gather, relatively resistant to tampering, and convenient for delivery.
A section measuring 1.5 inches of around 200 hair strands (roughly the size of a #2 pencil) closest to the scalp will yield 100mg of hair, which is the optimal sample size for analysis and confirmation tests. For tests such as EtG, extensions, and/or panels exceeding 10, a 150mg specimen is advisable. We suggest measuring the specimen using a jeweler's scale. If scalp hair is not an option, a comparable amount of body hair may be obtained. When we refer to head hair, it specifically means scalp hair. Body hair includes all other types (facial, axillary, etc.).
Process Overview
The laboratory workflow for processing a drug test outcome involves four essential stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the preliminary handling of a specimen into a lab's system. This process involves confirming that the specimen was correctly sealed and dispatched, providing a random LAN (Laboratory Accessioning Number), and finalizing any extra data input missing from an electronic chain of custody system.
Screening employs an initial rapid assessment for potential drug use. While Screening offers a cost-efficient method for excluding drug usage in most specimens, any positive result needs verification for legal admissibility. Presumptive positive samples in Screening require secondary confirmation.
If a sample shows a presumable positive in the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. In this phase, substances are pulled from hair at a significantly lower concentration than other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.
Verification of any positive screening outcome is performed via GC/MS, GC/MS/MS or LC/MS/MS. All samples with presumptive positives undergo washing before confirmation when necessary. The complete laboratory procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
