Hair analysis has emerged as an effective method for detecting drug and alcohol consumption. Hair captures a long-term record of alcohol and drug presence by embedding biomarkers within the hair strand's fibers as it grows. When hair is gathered close to the scalp, it can offer a detection timeframe of approximately three months for alcohol and drugs. The collection process is straightforward, making it tough to falsify, and it's also convenient for shipping.
A sample measuring 1.5 inches and comprising about 200 hair strands (equivalent to the thickness of a #2 pencil) nearest to the scalp amounts to 100mg of hair, which is the perfect sample size for both screening and confirmation. However, for EtG testing, supplementary tests, and tests exceeding 10 panels, 150mg of the hair sample is preferable. Using a jeweler’s scale for weighing the sample is advised. In the absence of scalp hair, equivalent body hair can be used. When referring to head hair, it specifically means scalp hair. Body hair encompasses all other types of hair, including facial and axillary.
Process Overview
The process for laboratory analysis of a drug test result comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial phase of processing a specimen into the lab’s system. This step ensures that the specimen was sealed and transported correctly, assigns a random LAN (Laboratory Accessioning Number), and addresses any extra data entry required beyond what an electronic chain of custody system supplies.
Screening acts as an initial rapid assessment for drugs of abuse. While it is a cost-efficient method to eliminate the use of drugs in most samples, a positive result in Screening needs confirmation to be legally admissible. Any samples yielding a presumptive positive during Screening necessitate further confirmation.
When a sample shows a presumptively positive result during Screening, additional hair is extracted from the initial sample and readied for Extraction. In this step, drugs are extracted from the hair at a significantly lower concentration compared to other methods (like urine or oral fluid), underscoring why hair drug testing is the most complex method to conduct.
Confirmation of any positive Screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if required. The comprehensive laboratory procedure, from Accessioning to Confirmation, is appraised following both the CAP (College of American Pathologists) Hair guidelines and the ISO / IEC 17025 standards accreditation.
