Hair testing is now regarded as an effective method for identifying alcohol and drug consumption. It captures a long-term history of these substances by embedding biomarkers within the fibers of the hair as it grows. When collected near the scalp, hair can offer a detection period of up to 3 months for both alcohol and drugs. This method is straightforward to gather, relatively tough to tamper with, and convenient for transportation.
A hair sample measuring 1.5 inches, consisting of around 200 strands (approximately the thickness of a #2 pencil) closest to the scalp, will yield 100mg, which is the optimal amount for both screening and verification. For EtG, add-ons, or tests exceeding 10 panels, 150mg is advised. Using a jeweler’s scale to measure the sample is recommended. If scalp hair is lacking, an equivalent amount of body hair can be used. When mentioning head hair, it only refers to scalp hair, while body hair includes all other types (facial, axillary, etc.).
Process Overview
The key stages in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the primary handling of a sample into the lab's system. This involves confirming that the sample was sealed and dispatched correctly, allotting a random LAN (Laboratory Accessioning Number), and fulfilling any further data entry absent in an electronic chain of custody system.
Screening entails a preliminary rapid assessment for illicit drugs. While it is a cost-efficient method to exclude drug use in most samples, a positive screening outcome necessitates confirmation for legal admissibility. Samples that are preliminarily positive during Screening need a follow-up confirmation.
If a sample is preliminarily positive in Screening, extra hair is extracted from the original sample for the Extraction process. In this phase, drugs are removed from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging procedure to execute.
Confirmation of any positive outcomes from screening is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All preliminary positive samples are cleansed prior to confirmation, if necessary. The complete lab procedure from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation standards.
