Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair captures a lengthy record of substances by embedding biomarkers within the strands of hair as they grow. When cut near the scalp, hair can reveal substance use over an interval of up to three months. This method is straightforward to collect, somewhat resistant to tampering, and convenient to transport.
A 1.5-inch section consisting of roughly 200 hair strands (similar in diameter to a #2 pencil) taken from close to the scalp amounts to 100mg of hair, which is ideal for both initial screening and confirmation purposes. For tests like EtG, additional options, and those exceeding 10 panels, a sample quantity of 150mg is preferable. It is advisable to measure the sample using a jeweler’s scale. In the absence of scalp hair, a similar quantity of body hair is an acceptable substitute. Note that when referring to head hair, it implies scalp hair exclusively. Body hair encompasses all other hair types (such as facial, axillary, etc.).
Process Overview
The procedure for processing a drug test sample in the lab consists of four stages: Accessioning, Screening, Extraction, and Confirmation.
The Accessioning phase incorporates entering a sample into the lab's system. This step involves ensuring the sample was securely sealed and properly sent, assigning a unique LAN (Laboratory Accessioning Number), and recording any missing data not included by an e-chain of custody protocol.
Screening performs a primary analysis for illicit substances. While this step is a budget-friendly approach to ignore drug presence in most samples, a positive result here necessitates a confirmation for it to be legally acceptable. Any samples yielding a positive preliminary result must undergo additional confirmation.
For samples showing a positive indication during Screening, more hair is extracted from the original sample and prepared for Extraction. At this juncture, the hair is processed to isolate drugs at concentrations far lower than other methods (like urine or saliva), rendering hair drug analysis among the more intricate approaches.
Positive Screening outcomes are validated via GC/MS, GC/MS/MS, or LC/MS/MS. Previously positive samples are cleaned as needed before confirmation. The comprehensive lab process, from Accessioning through Confirmation, adheres to oversight under CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accrediting standards.
