Hair testing is recognized as an effective method for detecting drug and alcohol consumption. The hair strands capture biomarkers within the fibers as they grow, providing an extensive history of substance use. By collecting hair near the scalp, it offers approximately a three-month window for tracing alcohol and drug usage. Hair is easy to gather, hard to tamper with, and straightforward to transport.
By cutting a 1.5-inch section of around 200 strands of hair (roughly the girth of a #2 pencil) near the scalp, you obtain 100mg of hair, which is the ideal amount for testing and validation. For EtG, additional analysis, or tests exceeding 10 panels, 150mg is preferred. It is advisable to weigh the sample with a jeweler’s scale. If scalp hair cannot be obtained, a similar mass of body hair can be used. When discussing head hair, it refers solely to scalp hair, while body hair encompasses all other types (such as facial and underarm).
Process Overview
The drug test result processing in a lab comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first phase of inputting a sample into a lab's system. This step ensures the sample is properly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and includes any additional data entry not covered by an electronic chain of custody setup.
Screening performs an initial drug abuse inspection. While it effectively identifies drug absence in most samples, confirmed results are needed for legal validity. Samples showing presumed positivity during Screening demand secondary confirmation.
Should a sample result in presumed positivity at the Screening phase, extra hair is taken from the initial specimen for further Extraction. In Extraction, drugs are removed from the hair at a concentration much lower than other methods (e.g., urine or saliva), making hair drug screening the most challenging to execute.
GC/MS, GC/MS/MS, or LC/MS/MS is employed to verify any positive screen results. All presumed positive samples undergo a washing prior to confirmation as necessary. The comprehensive lab process covering Accessioning to Confirmation is assessed per CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation.
