Hair testing has become recognized as a significant means for identifying the use of drugs and alcohol. Hair delivers a comprehensive history of alcohol and drugs by embedding biomarkers in the fibers of the hair strand as it grows. When gathered near the scalp, hair can reveal a detection range of up to roughly three months for alcohol and drugs. Hair is easy to collect, relatively resistant to tampering, and convenient to transport.
A 1.5-inch sample, consisting of approximately 200 strands of hair (similar in size to a #2 pencil) nearest to the scalp, yields 100mg of hair, which is the preferred sample size for both screening and confirmation. For EtG, supplemental tests, and/or examinations exceeding 10 panels, 150mg of the hair sample is advised. It is suggested to use a jeweler's scale for weighing the specimen. If scalp hair isn't obtainable, a comparable amount of body hair can be used. When mentioning head hair, it specifically refers to scalp hair. Body hair denotes all other hair categories (facial, axillary, etc.).
Process Overview
The primary steps involved in lab processing for drug test results are: Accessioning, Screening, Extraction, and Confirmation.
Accessioning deals with the preliminary processing of a sample within a lab's framework. This process includes ensuring the sample was properly sealed and delivered, provisioning a random LAN (Laboratory Accessioning Number), and executing any further data entry not supplied by an electronic chain of custody protocol.
Screening provides an initial rapid examination for drugs of abuse. Screening is a budget-friendly method to rule out drug usage in most samples; however, a positive screen needs confirmation for court acceptance. Any samples that test presumptively positive in Screening require subsequent confirmation.
When a sample tests presumptively positive during Screening, additional hair is taken from the original specimen in preparation for Extraction. Here, drugs are derived from hair at a considerably lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug screening one of the most challenging methodologies to carry out.
Confirmation of any positive screening result proceeds through GC/MS, GC/MS/MS or LC/MS/MS. All samples that preliminarily tested positive are cleaned before final confirmation if necessary. The complete lab process, from Accessioning to Confirmation, undergoes review under both the CAP (College of American Pathologists) Hair specification and compliance with ISO / IEC 17025 standards.
