Hair analysis has evolved into an effective means for detecting drug and alcohol consumption. Hair captures a long-term record of alcohol and drugs by encasing biomarkers within the fibers of the developing hair shaft. When taken from near the scalp, hair can offer roughly a 3-month detection timeframe for alcohol and drugs. Collecting hair is straightforward, moderately hard to tamper with, and convenient to transport.
A 1.5-inch segment of roughly 200 hair strands (approximately the size of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal sample for screening and verification. For EtG, additional tests, and/or tests exceeding 10 panels, 150mg of the sample is advisable. We suggest weighing the sample on a jeweler's scale. If scalp hair is absent, a similar amount of body hair can be gathered. When we mention head hair, we mean scalp hair exclusively. Body hair denotes all other hair kinds (facial, axillary, etc.).
Process Overview
The four primary stages in the lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial entry of a sample into a lab's system. This includes confirming the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and finalizing any extra data input not provided by an electronic custody chain.
Screening conducts an initial rapid assessment for drugs of abuse. Although Screening is an economical means to eliminate drug presence in the majority of samples, a positive screen requires confirmation to be court-admissible. Samples that are tentatively positive in Screening need a further confirmation.
If a sample shows a tentative positive in the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. In this phase, drugs are extracted from hair at a significantly lower concentration than other methods (e.g., urine or oral fluid), which is why hair drug screening presents the most challenging methodology.
Confirmation of any positive screening outcome is carried out via GC/MS, GC/MS/MS, or LC/MS/MS. All tentative positive samples undergo washing before confirmation as required. The entire lab process, from Accessioning to Confirmation, is reviewed under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
