The utilization of hair testing has emerged as an effective means for uncovering drug and alcohol usage. By encapsulating biomarkers within the fibers of the developing hair strand, hair offers an extended history of alcohol and other substances. When collected near the scalp, hair can offer approximately a 3-month detection period for these substances. Collection of hair is straightforward, less prone to tampering, and convenient for shipping.
Collecting a 1.5-inch sample consisting of roughly 200 hair strands (comparable to a #2 pencil) nearest to the scalp yields 100mg of hair, the perfect sample size for screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, a sample of 150mg is suggested. We advise weighing the sample using a jeweler’s scale. If scalp hair is not present, an equivalent volume of body hair may be collected. References to head hair specify only scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).
Process Overview
The primary steps in processing a drug test result in a laboratory are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into the laboratory's system. This verifies that the sample was appropriately sealed and dispatched, allocates a random LAN (Laboratory Accessioning Number), and finalizes any extra data entry not included by an electronic chain of custody system.
Screening consists of a preliminary swift examination for drugs of abuse. Though Screening is an economical approach to rule out drug use in most samples, a confirmed positive screen is essential to hold up in court. Any samples that show presumptive positivity in Screening need a subsequent confirmation.
If presumptively positive in the Screening phase, additional hair is taken from the primary specimen for Extraction. During Extraction, drugs are drawn from hair at much lower concentrations than other methods (such as urine or oral fluid), making hair drug screening the most complex approach to execute.
Confirmation of any positive screening outcome is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo washing before confirmation, as needed. The entire laboratory procedure from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
