Hair testing emerges as a potent method for identifying drug and alcohol consumption. Hair holds a comprehensive account of alcohol and other drug usage by encapsulating biomarkers within the fibers of the growing hair. Collected near the scalp, a hair sample can offer up to a 3-month detection window for alcohol and drugs. The process of hair collection is straightforward, challenging to tamper with, and convenient for transportation.
A sample of 1.5-inch length comprising about 200 strands (comparable to the thickness of a #2 pencil) near the scalp yields 100mg of hair, which is optimal for both screening and confirmation. For assessments involving EtG, additional tests, or tests exceeding 10 panels, a specimen amount of 150mg is advisable. Utilizing a jeweler’s scale for weighing the specimen is suggested. In the absence of scalp hair, a comparable quantity of body hair could be utilized. In this context, head hair signifies only scalp hair, whereas body hair denotes all other types of hair (facial, axillary, etc.).
Process Overview
The primary procedural stages in the laboratory analysis of a drug test result encompass Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial integration of a sample into the laboratory’s workflow. This phase ensures that the sample was appropriately sealed and dispatched, allocates a unique LAN (Laboratory Accessioning Number), and finalizes any pending data entry that hasn’t been captured by an electronic chain of custody protocol.
Screening involves a preliminary fast analysis for drug substances. Although Screening is efficient for eliminating drug use possibilities in most samples, any positive finding must undergo confirmation to be valid in court. Samples indicating a presumptive positive in Screening demand subsequent confirmation.
Should a sample register as presumptive positive during Screening, further hair is extracted from the original specimen for the Extraction phase. Drugs are drawn out from hair at significantly lower concentrations than seen in other testing mediums (e.g., urine or oral fluids), hence making hair drug screening the most challenging methodology to execute.
Confirming any positive screening outcome is facilitated via GC/MS, GC/MS/MS, or LC/MS/MS methods. Before confirmation, presumptive positive samples are cleansed as necessary. The complete laboratory sequence from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
