The perception of hair testing has evolved into recognizing it as an effective means for detecting drug and alcohol consumption. Hair can capture biomarkers within its fibers, offering a timeline of substance use. Collected near the scalp, it can indicate the presence of alcohol and drugs for up to three months. Hair collection is straightforward, relatively tamper-resistant, and conveniently transported.
To provide an optimal sample, a 1.5-inch segment of approximately 200 strands of hair (resembling the size of a #2 pencil) near the scalp yields 100mg, which suffices for screening and confirmation. For tests like EtG, additional analyses, or beyond 10 panels, 150mg is advised. We suggest using a jeweler’s scale to measure the specimen. If scalp hair is unavailable, a corresponding amount of body hair is acceptable. When indicating head hair, it specifically means scalp hair, whereas body hair encompasses other types (facial, axillary, etc.).
Process Overview
The laboratory processing for a drug test result includes Accessioning, Screening, Extraction, and Confirmation as primary steps.
During Accessioning, the sample is initially integrated into a lab’s system by checking proper sealing and shipping, assigning a random Laboratory Accessioning Number (LAN), and completing any further data input absent from an electronic chain of custody system.
Screening constitutes a preliminary scrutinization for substance misuse. While Screening economically rules out drug presence for most samples, a positive result needs Confirmation to stand as evidence in court. Presumptive positives in Screening necessitate a supplementary confirmation.
Should the Screening phase yield a presumptively positive result, additional hair is taken from the existing sample for the Extraction phase. Here, drug levels are extracted from the hair at concentrations lower than in other methods (e.g., urine or oral fluid), making hair drug testing notably complex.
For any screenings testing positive, Confirmation follows through GC/MS, GC/MS/MS, or LC/MS/MS. Samples with presumptive positive results undergo washing before Confirmation as required. The entire process, from Accessioning to Confirmation, adheres to the CAP (College of American Pathologists) Hair designation and is accredited by ISO / IEC 17025 standards.
