Hair testing is now regarded as a potent method for identifying drug and alcohol usage. Hair offers a prolonged history of alcohol and other substances by capturing biomarkers in the fibers of the developing hair strand. When obtained near the scalp, hair provides an approximate 3-month detection timeframe for alcohol and other substances. Hair is straightforward to gather, relatively hard to tamper with, and simple to transport.
A 1.5-inch piece of roughly 200 hair strands (comparative to the diameter of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal amount for both screening and verification. For EtG, supplemental analysis, and/or tests exceeding 10 panels, 150mg of the sample is suggested. We advocate measuring the sample using a jeweler’s scale. If head hair is unavailable, a comparable quantity of body hair can be collected. When mentioning head hair, it exclusively pertains to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result is composed of four pivotal steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample undergoes initial processing to be integrated into a laboratory’s system. This step includes confirming the sample was sealed and dispatched correctly, assigning a random LAN (Laboratory Accessioning Number), and performing any additional data entry not supplied by an electronic chain of custody system.
Screening entails a preliminary rapid examination for drug abuse. While Screening is an economical method to discount drug usage for most samples, a positive screen necessitates confirmation to be valid in court. Samples that show a presumptive positive in Screening require further confirmation.
If a sample is presumptively positive during the Screening phase, additional hair is taken from the original sample and readied for Extraction. In this stage, drugs are extracted from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), making hair drug screening the most challenging procedure to conduct.
Confirmation of any positive screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with a presumptive positive result are cleaned prior to confirmation as necessary. The entire laboratory procedure from Accessioning through Confirmation is inspected under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
