Hair testing is recognized as a potent method for identifying drug and alcohol use. Hair captures a prolonged history of alcohol and other drugs by incorporating biomarkers within the fibers of the developing hair strand. If gathered near the scalp, hair can offer up to around a 3-month detection period for alcohol and other substances. Hair is straightforward to gather, relatively challenging to tamper with, and simple to transport.
A 1.5-inch portion consisting of approximately 200 hair strands (about the width of a #2 pencil) nearest to the scalp will provide 100mg of hair, which is the optimal sample for screening and verification. For EtG, supplementary tests, and/or tests exceeding 10 panels, 150mg of the sample is advised. We advise weighing the sample using a jeweler’s scale. If scalp hair isn't accessible, a similar amount of body hair can be collected. By head hair, we mean scalp hair only. Body hair refers to all other types of hair (facial, axillary, etc.).
Process Overview
The primary stages in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a sample into a lab’s system. This step verifies that the sample was properly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and finishes any additional data entry not covered by an electronic chain of custody system.
Screening deals with an initial rapid evaluation for drug abuse. Though Screening is an economical way to eliminate drug usage in most samples, a positive screening must be confirmed to be admissible in legal proceedings. Any samples with presumptive positive results in Screening require further confirmation.
Should a sample show a presumptive positive result in the Screening phase, more hair is drawn from the original sample and prepped for Extraction. During this phase, drugs are extracted from hair at a significantly lower concentration than other techniques (such as urine or oral fluid), making hair drug screening the most complex method to execute.
Confirmation of any positive screen finding is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed as necessary before confirmation. The full laboratory process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.
