Hair testing is regarded as an effective method for identifying drug and alcohol consumption. Hair captures a lengthy history of alcohol and other substances by retaining biomarkers within the strands. A sample taken near the scalp offers about a 3-month window for detecting alcohol and drugs. Hair is easy to gather, challenging to tamper with, and simple to transport.
A sample of 1.5 inches, consisting of around 200 hairs (roughly the thickness of a #2 pencil) from the scalp, produces 100mg of hair, which is the perfect amount for initial testing and validation. For EtG or tests above 10 panels, 150mg is advisable. It's best to measure the sample using a jeweler’s scale. If scalp hair is missing, a similar amount of body hair can be used. 'Head hair' refers specifically to scalp hair, while 'body hair' includes all other hair types (beard, armpit, etc.).
Process Overview
The laboratory processing of a drug test result is comprised of four principal stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails incorporating the sample into the laboratory's system. This step ensures the sample was correctly sealed and dispatched, assigns a random Laboratory Accessioning Number (LAN), and finishes any extra data entry not covered by an electronic chain of custody system.
Screening is a preliminary assessment for substances of abuse. Although a cost-effective method for excluding drug use in most samples, a positive screening needs confirmation to be legally acceptable. Presumptively positive samples in Screening necessitate follow-up confirmation.
If Screening suggests a sample is positive, additional hair is taken from the original and arranged for Extraction. Drugs are extracted from hair at significantly reduced concentrations than other methods (e.g., urine or oral fluid), making hair drug screening the most complex method.
Confirmation of any positive result in Screening is done using GC/MS, GC/MS/MS, or LC/MS/MS. Samples with presumptive positives are washed before confirmation if necessary. The full process from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
