Hair analysis has gained recognition as an effective method for identifying substance and alcohol consumption. Hair retains a comprehensive history of substances by embedding indicators within the strands as they grow. If obtained near the scalp, it can reveal substance usage up to roughly three months prior. Hair is easy to gather, challenging to tamper with, and straightforward to transport.
A 1.5-inch segment of approximately 200 hairs (equivalent to a #2 pencil thickness) taken closest to the scalp yields 100mg, ideal for analysis and verification. For EtG, additional tests, or tests beyond 10 panels, 150mg of hair is suggested. Using a jeweler's scale for weighing is advisable. Should scalp hair be absent, a comparable weight of body hair is an alternative. In context, "head hair" refers strictly to the scalp, while "body hair" encompasses other hair types (face, armpits, etc.).
Process Overview
The four critical phases in processing a drug test in a lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial incorporation of a sample into the lab's system, ensuring proper sealing and shipment, issuing a unique LAN (Laboratory Accessioning Number), and completing any supporting data entry not provided electronically.
Screening is a preliminary evaluation for substances. Though economical for excluding drugs in most samples, positive screenings require confirmation for legal validity. Samples showing presumptive positives in Screening need corroborative testing.
When Screening shows a presumptive positive, additional hair is extracted for preparation in Extraction. This phase involves isolating drugs from hair at significantly lower levels than other techniques (e.g., urine, oral fluid), explaining the complexity of hair drug testing.
Positive Screening outcomes are verified through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo necessary washing before verification. The complete test process from Accessioning to Confirmation is scrutinized under CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation.
