Hair analysis is now recognized as a potent means for identifying the use of drugs and alcohol. By embedding biomarkers within the fibers, hair retains a long-term record of alcohol and drug consumption. Collected near the scalp, hair can reveal drug and alcohol usage over an approximate 3-month period. The process of hair collection is straightforward, relatively tamper-proof, and convenient for transport.
A sample measuring 1.5 inches, containing roughly 200 hair strands (comparable to the thickness of a #2 pencil), cut nearest to the scalp, yields around 100mg of hair, which is the preferred quantity for both screening and validation. For EtG analysis, additional tests, or panels exceeding 10, a specimen of 150mg is suggested. Utilizing a jeweler’s scale for measurement is advised. In scenarios without available scalp hair, equivalent body hair can be used. When mentioning head hair, we are exclusively referencing scalp hair, while body hair encompasses all other types (facial, armpits, etc.).
Process Overview
The drug test result processing in laboratories involves four fundamental stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary phase where a sample is integrated into the laboratory’s system. This stage ensures the sample is correctly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes any supplementary data input absent from an electronic chain of custody system.
Screening serves as the initial evaluation for abusive substances. While it offers a cost-effective method for excluding drug use in most samples, a positive outcome in a screen necessitates confirmation to be permissible in legal contexts. Samples showing presumptive positivity in Screening must undergo a secondary confirmation.
For samples that test positive in Screening, additional hair is taken from the original sample and used in the Extraction phase. During Extraction, drugs are isolated from hair at significantly lower concentrations than other methods (such as urine or oral fluid), highlighting the complexity of hair drug screening.
Positive screening outcomes are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptively positive samples undergo washing before the confirmation as required. The whole procedure from Accessioning through to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation and is aligned with ISO / IEC 17025 accreditation standards.
