Hair analysis has gained recognition as an effective method for uncovering drug and alcohol consumption. Hair captures a historical record of drugs and alcohol by embedding biomarkers within the strands of growing hair. When harvested near the scalp, hair can deliver a detection period extending up to about three months for alcohol and drugs. It’s straightforward to gather, relatively hard to tamper with, and simple to transport.
A sample of 1.5 inches, containing approximately 200 hairs (roughly comparable to a #2 pencil in thickness) from nearest the scalp yields 100mg of hair, ideal for testing and confirmation. For evaluations such as EtG, additional tests, and/or those exceeding 10 panels, 150mg of the hair sample is advised. We suggest using a jeweler’s scale to measure the specimen. If scalp hair isn’t available, a similar amount of body hair may be used. References to head hair specifically denote scalp hair. Body hair covers all other types (like facial, axillary, etc.).
Process Overview
The key steps in processing a lab drug test result consist of Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the preliminary processing when a sample enters a lab's system. This process includes validation that the sample was sealed and transported suitably, assignment of a random LAN (Laboratory Accessioning Number), and finalizing any additional data inputs not included by an electronic chain of custody system.
The Screening phase consists of an initial speed check for drug misuse. Whereas Screening offers a cost-effective measure to eliminate drug usage for the majority of cases, a positive screen must undergo confirmation for judicial admissibility. Samples appearing presumptively positive in Screening require secondary confirmation.
For a sample deemed presumptively positive at the Screening stage, additional hair is extracted from the initial sample and readied for Extraction. In this phase, drug molecules are drawn from hair at much lower amounts than alternate methods (e.g., urine or oral fluid), contributing to hair drug screening being the most challenging method to perform.
Confirmation of any positive result from screening is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All samples tagged as presumptively positive undergo washing before confirmation if required. The lab process from Accessioning to Confirmation is overseen under both the CAP (College of American Pathologists) Hair recognition and ISO / IEC 17025 accreditation.
