Hair analysis is recognized as a potent method for detecting drug and alcohol consumption. It offers an extensive history of substance use by embedding biomarkers within the fibers of the maturing hair. When obtained near the scalp, hair can reveal substance use within an approximate three-month detection span. The collection process is straightforward, challenging to tamper with, and convenient to transport.
A sample measuring 1.5 inches, consisting of approximately 200 hair strands (similar to the dimensions of a #2 pencil) taken closest to the scalp, yields 100mg of hair, which is the ideal quantity for both screening and confirmation. For tests involving EtG, additional features, and those exceeding 10 panels, it is advised to gather 150mg of the sample. Utilizing a jeweler’s scale for weighing the sample is recommended. In instances where scalp hair is inaccessible, a comparable amount of body hair can be used. When discussing head hair, we specifically mean scalp hair. Body hair encompasses all other forms (facial, axillary, etc.).
Process Overview
There are four primary phases in laboratory processing for drug testing: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial integration of a sample into the laboratory’s system. This step involves confirming the proper sealing and shipment of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplementary data input not covered by an electronic chain of custody system.
Screening pertains to an initial rapid check for drugs of abuse. While Screening offers a cost-efficient method to exclude drug use for most samples, a positive result requires confirmation to be court-admissible. Presumptively positive samples during Screening necessitate a subsequent confirmation.
When a sample tests presumptively positive during Screening, additional hair is extracted from the original sample for the Extraction phase. In this phase, drugs are separated from hair at significantly lower concentrations than in alternative methodologies (such as urine or oral fluid), marking hair drug screening as one of the most complex methodologies.
GC/MS, GC/MS/MS, or LC/MS/MS methods are used for the Confirmation of any positive results from Screening. Prior to Confirmation, all samples with presumptive positives are washed if necessary. The complete laboratory procedure, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
