Hair analysis is now recognized as a formidable method for identifying drug and alcohol consumption. Hair offers an extended history of alcohol and other substances by embedding biomarkers in the structure of the emerging hair strand. When extracted near the scalp, hair can deliver up to a roughly 90-day detection period for alcohol and drugs. Hair is straightforward to gather, relatively challenging to tamper with, and simple to transport.
A 1.5-inch section of about 200 hairs (about the size of a #2 pencil) nearest the scalp will produce 100mg of hair, which is the perfect sample size for testing and verification. For EtG, additional analysis, or tests exceeding 10 panels, 150mg of the sample is suggested. We advise using a jeweler’s scale to weigh the sample. If scalp hair cannot be obtained, a proportional amount of body hair can be used. By head hair, we mean only scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The four critical steps in the lab processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial handling of a sample into a lab’s system. This involves verifying that the sample was properly sealed and sent, giving it a random LAN (Laboratory Accessioning Number), and finishing any extra information not covered by an electronic chain of custody system.
Screening consists of a preliminary rapid assessment for drugs of abuse. Although Screening is an economical method to exclude drug usage on most samples, a positive screen needs confirmation to be valid in legal situations. Any samples presumptively positive in Screening require a subsequent confirmation.
If a sample appears positive during the Screening phase, additional hair is taken from the initial sample and readied for Extraction. During this phase, drugs are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), which is why hair drug analysis is considered the most complex method to execute.
Confirmation of any positive screen result is done via GC/MS, GC/MS/MS or LC/MS/MS. All presumptively positive samples are cleaned before confirmation if necessary. The whole laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
