Hair analysis is recognized as an effective means for identifying substance and alcohol consumption. Hair captures a long-lasting record of these substances by embedding biomarkers in the strands as they grow. Sampling hair near the scalp allows for up to nearly a 3-month period for detecting alcohol and drugs. Collecting hair is straightforward, tampering is relatively hard, and transportation is simple.
A section measuring 1.5 inches and containing roughly 200 strands (similar in size to a #2 pencil) close to the scalp will yield 100mg of hair, which is ideal for testing and validation. For EtG, additional tests, and/or tests beyond 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale to weigh the sample. If scalp hair isn’t an option, an equivalent amount of body hair can be used. “Head hair†refers specifically to scalp hair, while “body hair†includes all other types (facial, axillary, etc.).
Process Overview
The key stages in the laboratory analysis of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step in entering a sample into a lab’s system. It involves confirming that the sample was correctly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and completing any other data entry not included by an electronic chain of custody system.
Screening is an initial rapid assessment for drug abuse. Although Screening is a cost-efficient method for ruling out drug use in most samples, a positive result needs confirmation for court admissibility. Therefore, any presumed positives from Screening require further confirmation.
Should a sample test presumptively positive in Screening, additional hair is collected from the sample for Extraction. In this phase, hair is utilized to extract drugs at significantly lower concentrations than other methods (e.g., urine or saliva), making hair drug screening a challenging procedure to execute.
To confirm any positive result from screening, GC/MS, GC/MS/MS, or LC/MS/MS techniques are used. Any samples presumed positive undergo washing before confirmation if needed. The laboratory process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 accreditation.
