Hair examination has emerged as a robust resource in identifying the use of drugs and alcohol. The hair offers an extended historical record of drugs and alcohol through the capture of biomarkers within the hair fibers as they grow. When obtained from near the scalp, the hair can indicate drug or alcohol use over a roughly three-month period. Hair collection is straightforward, relatively resistant to tampering, and conveniently transported.
A 1.5-inch lock of about 200 hairs (approximately matching the width of a #2 pencil) near the scalp equates to 100mg of hair, which is the preferred amount for testing and verification. For EtG, supplementary tests, and/or examinations exceeding 10 panels, 150mg of the sample is suggested. It's advisable to measure the sample using a jewelry scale. If head hair cannot be obtained, an equivalent quantity of body hair is suitable. References to head hair imply only scalp hair. Body hair encompasses all other forms such as facial and axillary hair.
Process Overview
The laboratory procedure for processing drug test outcomes involves four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preliminary handling of a sample within a lab's framework. It's essential to check that the sample was appropriately sealed and dispatched, generate a random LAN (Laboratory Accessioning Number), and fulfill any extra data entry absent from an electronic chain of custody system.
Screening executes an initial rapid probe for illicit drugs. While Screening is an economical strategy to exclude drug use for most samples, any positive result in this phase necessitates confirmation to stand in legal settings. Samples presumed positive in Screening must undergo further verification.
In cases of a presumptive positive outcome during Screening, extra hair is taken from the original sample for Extraction. Here, drugs are separated from hair at significantly lower concentrations than in other methods (such as urine or oral fluid), underscoring the complexity of hair drug analysis.
Verification of any positive outcomes from Screening is executed using GC/MS, GC/MS/MS, or LC/MS/MS. If required, all samples presumed positive are cleansed before confirmation. The complete analysis process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards of accreditation.
