An effective approach to identifying substance and alcohol usage is hair testing. Hair records a comprehensive history of substances by capturing markers within the strands as they grow. When gathered near the scalp, hair offers a detection span reaching roughly 90 days for both alcohol and other substances. The collection process is straightforward, with minimal risk of tampering, and the samples can be easily transported.
Obtaining a 1.5-inch specimen of roughly 200 hair strands (comparable to a #2 pencil's diameter) from near the scalp yields 100mg of hair, optimal for analysis and verification. For tests like EtG, panel add-ons, or those exceeding 10 panels, a 150mg sample is advised. Using a jeweler’s scale for accurate measurement is recommended. If scalp hair is lacking, equivalent amounts of body hair may be used. Specifically, head hair refers to scalp hair, whereas body hair includes all other types (like facial or axillary hair).
Process Overview
The key laboratory stages in drug test result processing comprise Accessioning, Screening, Extraction, and Confirmation.
Accessioning incorporates the initial integration of a sample into the lab's system. This phase checks the sealing and shipping accuracy, assigns a random Laboratory Accessioning Number (LAN), and handles any data entry omitted by an electronic custody documentation system.
Screening executes an initial swift analysis for substance presence. Although Screening offers an economical means to eliminate drug use possibilities for most samples, any positive screen must be corroborated for legal acceptance. Presumptive positive samples in Screening need further confirmation.
When a Screening stage sample is marked presumptive positive, additional hair is extracted from the initial sample for the Extraction phase. Here, substances are drawn from hair at concentrations significantly lower than seen in other tests (such as urine or oral swabs), highlighting why hair drug testing is among the most challenging methodologies.
Positive Screening results are validated through GC/MS, GC/MS/MS, or LC/MS/MS. All samples preliminarily positive undergo requisite washing before confirmation. The entire lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Note: Although often termed "hair follicle tests", the procedure examines the hair strand itself and not the root beneath the scalp.
