Hair analysis is esteemed as an effective means of identifying the consumption of drugs and alcohol. Hair strands encapsulate a prolonged record of alcohol and drug interactions by embedding biomarkers within the growing fibers. When procured near the scalp, hair can present a detection span of up to roughly 90 days for various substances. Collecting hair is easy, comparatively challenging to tamper with, and convenient to dispatch.
A 1.5-inch segment of around 200 hair strands (equivalent to the thickness of a #2 pencil) collected nearest to the scalp will yield 100mg of material, which is the optimal quantity for both screening and verification. For tests involving EtG, supplementary analyses, or going beyond 10-panel tests, a sample size of 150mg is advised. We propose using a jeweler’s scale for weight accuracy. If scalp hair is inaccessible, a similar measure of body hair might be taken. By head hair, we specifically mean scalp hair. Body hair is all other hair types (facial, axillary, etc.).
Process Overview
The laboratory handling of a drug test involves four key stages: Accessioning, Screening, Extraction, and Verification.
Accessioning is the initial phase of inputting a sample into a lab’s records. It consists of confirming the proper sealing and shipping of the sample, generating a unique LAN (Laboratory Accessioning Number), and finalizing any extra data input that an electronic chain of custody system might not have covered.
Screening is a preliminary swift assessment for substance misuse. Although Screening offers a cost-efficient method to eliminate most samples from further drug use suspicion, confirmation of a positive screen is necessary for legal acceptability. Samples indicated as potentially positive during Screening must undergo a subsequent confirmation process.
If a sample indicates a presumptive positive result during Screening, additional hair is extracted from the primary sample for the Extraction phase. This phase involves retrieving drugs from hair at lower concentrations than other techniques (such as urine or oral fluids), making hair drug analysis notably challenging to execute.
Verification of any positive Screening outcome is achieved using GC/MS, GC/MS/MS, or LC/MS/MS methods. Prior to verification, all samples showing presumptive positives undergo cleansing as required. The complete lab process from Accessioning through Confirmation is scrutinized under both the CAP (College of American Pathologists) hair guidelines and ISO / IEC 17025 accreditation standards.
