Hair analysis has emerged as an effective means for detecting drug and alcohol consumption. Hair retains a record of alcohol and drug intake over time by embedding biomarkers in the hair strand as it grows. When taken from near the scalp, hair can reveal drug and alcohol usage over a span of up to three months. Hair sampling is easy to perform, challenging to tamper with, and convenient to transport.
A sample measuring 1.5 inches and consisting of approximately 200 hair strands (about the thickness of a #2 pencil) gathered from close to the scalp provides 100mg of hair, which is the perfect amount for both screening and confirmatory purposes. For EtG, additional tests, and/or panels exceeding 10, a quantity of 150mg is advisable. It's suggested to use a jeweler’s scale for weighing the sample. In the absence of scalp hair, a comparable amount of body hair is acceptable. When mentioning head hair, we specifically mean scalp hair. Body hair includes all other types (such as facial and axillary).
Process Overview
The drug testing laboratory process comprises four key steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially integrated into the laboratory’s framework. This phase includes checking that the sample was properly sealed and delivered, generating a random LAN (Laboratory Accessioning Number), and inputting any additional necessary information not captured by an electronic chain of custody.
Screening provides a preliminary assessment for substance abuse. Despite being a cost-effective means to eliminate drug usage in most samples, a positive screen mandates further confirmation to be valid in legal contexts. Samples that show a presumptive positive during Screening will require additional confirmation.
When a sample is marked presumptively positive during Screening, more hair is extracted from the original sample to prepare for Extraction. This stage involves extracting drugs from hair at significantly reduced concentrations compared to other methods (such as urine or saliva), marking hair drug screening as one of the more complex methodologies.
Confirmation of any positive screening outcome is carried out using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Any samples labeled as presumptive positive undergo a washing process prior to confirmation when necessary. The laboratory procedure, from Accessioning through to Confirmation, aligns with CAP (College of American Pathologists) Hair designation standards and is accredited to ISO / IEC 17025 benchmarks.
