Hair testing has gained recognition as an effective method for detecting drug and alcohol usage. By trapping biomarkers within the fibers of the hair strand, hair offers a historical record of drug and alcohol consumption. When collected near the scalp, hair can offer a detection timeline of up to around three months for alcohol and drugs. Hair is easy to gather, challenging to tamper with, and straightforward to transport.
A 1.5-inch segment of roughly 200 hair strands (approximately the width of a #2 pencil) closest to the scalp yields 100mg of hair, the preferred amount for both screening and confirmation. For EtG, additional testing, and tests exceeding 10 panels, a larger sample of 150mg is advisable. It is suggested to measure the sample using a jeweler's scale. If scalp hair cannot be obtained, a comparable quantity of body hair may be used. References to head hair imply scalp hair specifically. Body hair denotes any other hair types (such as facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses the steps of Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary processing of a sample into the laboratory system. This process validates that the sample was securely sealed and properly shipped, assigns a random LAN (Laboratory Accessioning Number), and addresses any additional data entry omitted by an electronic chain of custody system.
Screening provides an initial examination for substances of abuse. While Screening serves as a cost-efficient method to exclude drug use in the majority of samples, a positive screen must be validated to be acceptable in legal proceedings. Samples that test presumptively positive during Screening require a follow-up confirmation.
For samples that test presumptively positive during Screening, additional hair is extracted from the original sample and readied for Extraction. In this phase, drugs are extracted from hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), which contributes to the complexity of hair drug screening.
Confirmation for any positive screening outcomes is performed via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing prior to confirmation when needed. The full laboratory process from Accessioning to Confirmation is assessed according to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
