Hair testing has emerged as an effective method for uncovering drug and alcohol consumption. Hair encapsulates a prolonged history of substances by embedding biomarkers within the fibers of the hair as it grows. When collected near the scalp, hair offers a detection range of up to 3 months for substances like alcohol. The process of collecting hair is straightforward, challenging to tamper with, and easy to transport.
A 1.5-inch section from around 200 hair strands (approximately the size of a #2 pencil) closest to the scalp yields a sample weighing 100mg, ideal for both initial screening and subsequent confirmation. For EtG, additional tests, or those beyond 10 panels, a specimen weight of 150mg is advisable. It is best to measure the sample using a jeweler’s scale. If scalp hair is inaccessible, a similar quantity of body hair can be obtained. "Head hair" specifically refers to scalp hair, while "body hair" includes all other types (such as facial or axillary hair).
Process Overview
The key phases in the laboratory workflow for drug test analysis include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where a sample is introduced into the lab system. This step ensures proper sealing and shipment of the sample, assigns a random LAN (Laboratory Accessioning Number), and handles any extra data input absent from an electronic custody chain.
Screening offers an initial check for substance abuse. Though Screening is a cost-effective approach for rejecting drug presence in most samples, a confirmed positive is needed for legal substantiation. Specimens showing presumptive positives during Screening must undergo further confirmation.
If a sample indicates a presumptive positive in Screening, additional hair from the initial sample is extracted for further analysis. During Extraction, drugs are isolated from hair at a significantly lower concentration compared to other methods (e.g., urine or oral fluid), illustrating the complexity of hair drug screening.
Confirmation of positive screening outcomes is achieved using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Before proceeding to confirmation, all presumptive positive specimens are cleaned as needed. The entire process from Accessioning to Confirmation is conducted under the CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 standards.
