Hair analysis is increasingly recognized as a significant approach for identifying drug and alcohol usage. Hair captures a detailed record of alcohol and other substances by embedding biomarkers in the hair strand's fibers as it grows. When gathered near the scalp, hair can reveal a detection window for substances and alcohol extending up to almost three months. Hair is straightforward to collect, hard to tamper with, and simple to transport.
A 1.5-inch sample comprising roughly 200 hair strands (similar to the width of a #2 pencil) closest to the scalp yields 100mg of hair, the optimal quantity for analysis and validation. For EtG, additional tests, and tests exceeding 10 panels, 150mg of the sample is advised. It is advisable to weigh the specimen with a jeweler’s scale. If scalp hair isn't an option, a proportional amount of body hair can be used. When mentioning head hair, it relates specifically to scalp hair. Body hair denotes all other types of hair (e.g., facial, axillary).
Process Overview
The laboratory processing of a drug test result comprises four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the sample's initial introduction into a lab system. This step ensures the sample's seal and shipment integrity, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data not furnished by an electronic chain of custody system.
Screening involves an expedited review for drugs of abuse. Screening offers an economical solution to dismiss drug usage in most cases, but a positive finding must be confirmed for court acceptability. Any samples indicating probable positivity in Screening necessitate further confirmation.
Upon a probable positive result in the Screening phase, additional hair is collected from the original sample and readied for Extraction. At this stage, drugs are separated from hair at a significantly lesser concentration compared to other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug screening.
Positive results from Screening are verified using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with potential positivity undergo washing before confirmation as required. The complete laboratory process from Accessioning to Confirmation is scrutinized under both CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standard accreditation.
