Hair examination has gained recognition as an effective method for identifying drug and alcohol consumption. By capturing biomarkers within the fibers of the developing hair strand, hair gives a prolonged history of alcohol and other substances. When collected near the scalp, hair can offer nearly a 3-month detection window for alcohol and drugs. Hair is easy to gather, fairly challenging to tamper with, and straightforward to transport.
A sample measuring 1.5 inches and consisting of around 200 hair strands (approximately the size of a #2 pencil) closest to the scalp will yield 100mg of hair, which is the ideal quantity for screening and confirmation. For EtG, additional tests, and tests beyond 10 panels, a specimen of 150mg is advised. It's suggested to weigh the specimen using a jeweler's scale. If scalp hair is unavailable, a similar amount of body hair may be gathered. When we refer to head hair, we are speaking exclusively about scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The four central steps involved in processing a drug test result in a laboratory are Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the preliminary processing of a sample into the laboratory system. This step entails ensuring the sample was properly sealed and shipped, allocating a random LAN (Laboratory Accessioning Number), and completing any extra data input not facilitated by an electronic chain of custody system.
Screening is a rapid preliminary check for drugs of abuse. Although Screening is an economical method to exclude drug use for most samples, a positive screen must be validated to be allowable in court. Any samples that yield a presumptive positive in Screening require secondary confirmation.
If a sample is presumptively positive at the Screening stage, additional hair is extracted from the initial specimen and prepped for Extraction. During this phase, drugs are extracted from hair at a considerably lower concentration than other methodologies (e.g., urine or oral fluid), making hair drug screening extremely challenging to execute.
Confirmation of any positive screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed prior to confirmation as necessary. The full laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the certification to ISO / IEC 17025 standards.
