Hair testing has become recognized as an effective instrument for identifying the use of drugs and alcohol. Hair captures a prolonged record of alcohol and drugs by embedding biomarkers within the fibers of the developing hair strand. When gathered near the scalp, it can offer up to roughly a 3-month detection period for alcohol and drugs. Hair is straightforward to gather, relatively hard to tamper with, and simple to transport.
A 1.5-inch segment of roughly 200 hair strands (comparable to the girth of a #2 pencil) near the scalp provides 100mg of hair, which is ideal for screening and confirmation. For EtG, additional tests, and/or those exceeding 10 panels, 150mg of the sample is advised. It is suggested to use a jeweler’s scale for weighing the sample. If scalp hair is not present, a comparable quantity of body hair can be obtained. References to head hair imply scalp hair only, while body hair signifies all other hair varieties (facial, axillary, etc.).
Process Overview
The four fundamental stages in lab processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning comprises the initial handling of a sample into a laboratory's framework. This procedure includes ascertaining that the sample was correctly sealed and dispatched, registering a random LAN (Laboratory Accessioning Number), and finalizing any additional information entry not supplied by an electronic chain of custody platform.
Screening incorporates an initial cursory analysis for drug misuse. While Screening is a budget-friendly approach to disqualify drug use in most samples, a positive screen must be validated to be legally acceptable. Any samples presumed positive in Screening necessitate a secondary confirmation.
Should a sample be presumably positive in the Screening phase, additional hair is taken from the original sample and readied for Extraction. At this phase, drugs are extracted from hair at a markedly lower concentration than other methods (such as urine or oral fluid), making hair drug testing the most challenging technique to conduct.
Confirmation of any positive screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all samples presumed positive are cleansed if necessary. The total laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
