Hair testing is increasingly viewed as a robust method for identifying drug and alcohol consumption. Hair offers an extended timeline by capturing biomarkers within the growing strand's fibers. Proximal scalp hair can reveal up to a 3-month history of drug and alcohol use. Collecting hair is easy, difficult to tamper with, and convenient for shipping.
A 1.5-inch hair sample, consisting of roughly 200 strands (comparable to a #2 pencil's width), yields 100mg, ideal for screening and confirmation. For EtG, additional analyses, or tests exceeding 10 panels, 150mg is suggested. Using a jeweler's scale to weigh the specimen is recommended. If scalp hair isn't accessible, an equivalent volume of body hair may be used. "Head hair" refers solely to scalp hair, while "body hair" encompasses all other hair (e.g., facial, axillary).
Process Overview
The primary steps in laboratory drug test processing are Accessioning, Screening, Extraction, and Confirmation.
Accessioning starts with integrating a sample into a lab's system. This step ensures proper sealing and shipping of the sample, assigns a unique Laboratory Accessioning Number (LAN), and inputs additional necessary data absent in electronic chain of custody systems.
Screening provides an initial, swift evaluation for drug abuse. Although Screening efficiently excludes drug use in most cases, confirmed testing is necessary for legal validity. Presumptively positive samples in Screening must undergo further confirmation.
If a sample tests presumptive positive in Screening, additional hair is prepared for Extraction. Here, drugs are extracted at significantly lower concentrations than in other methods (e.g., urine, oral fluid), highlighting the complexity of hair drug testing.
Confirmation uses GC/MS, GC/MS/MS, or LC/MS/MS for positive Screen results. Samples showing presumptive positives are washed pre-confirmation when required. The entire process from Accessioning to Confirmation is evaluated per CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
