Hair analysis has emerged as an effective means for identifying drug and alcohol consumption. It allows for an extended record of substance usage by encasing indicators within the hair's developing fibers. When sourced near the scalp, hair can offer up to a 3-month timeframe for detecting alcohol and other substances. Collecting hair is straightforward, relatively hard to tamper with, and simple to transport.
A sample measuring 1.5 inches of roughly 200 hair strands (comparable to a #2 pencil in thickness) nearest the scalp yields 100mg of hair, which is the optimal amount for analysis and validation. For EtG tests, add-ons, and tests exceeding 10 panels, 150mg of hair is advised. Using a jeweler’s scale for weighing the specimen is suggested. If scalp hair cannot be used, a comparable quantity of body hair may be taken. References to head hair pertain specifically to scalp hair. Body hair includes all other types (facial, axillary, etc.).
Process Overview
The core stages involved in processing a drug test result at the lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the phase where a sample first enters a lab's system. It involves checking that the sample was properly sealed and sent, assigning a unique LAN (Laboratory Accessioning Number), and completing any further data entry not covered by an electronic custody chain system.
Screening involves a preliminary quick test for drug misuse. While Screening is an economical method to verify drug absence in most samples, a positive result must be substantiated to be legally defensible. Any samples preliminarily positive in Screening need further validation.
If a sample shows presumptive positivity during Screening, additional hair from the initial batch is used for Extraction. Here, drugs are drawn out of hair at a notably lower concentration compared to other methods (like urine or oral fluid), which is why hair drug analysis is the most challenging methodology.
Confirmation of any positive screening result is conducted with GC/MS, GC/MS/MS, or LC/MS/MS. All samples suggesting positivity are cleansed before confirmation if required. The comprehensive laboratory protocol from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair standards and compliance with ISO / IEC 17025 norms.

Limitations:
Note: Although commonly termed "hair follicle tests," the examination focuses on the hair strand, not the follicle beneath the scalp.
