Hair analysis has become recognized as a robust method for identifying drug and alcohol consumption. Hair retains a historical record of substances by encasing biomarkers within the growing strand. When gathered near the scalp, hair can indicate usage of substances such as alcohol for roughly three months. Collection is straightforward, tampering is somewhat complex, and shipping is uncomplicated.
A 1.5-inch section consisting of about 200 hair strands (comparable to a #2 pencil) nearest to the scalp yields 100mg of hair, ideal for examination and verification. For EtG enhancements and/or tests exceeding 10 panels, 150mg is advised. Utilizing a jeweler's scale to weigh the sample is suggested. In the absence of scalp hair, an equivalent volume of body hair can be obtained. "Head hair" specifically denotes scalp hair, whereas "body hair" includes all other types (facial, axillary, etc.).
Overview of the Procedure
The four primary stages in processing a drug test result in the laboratory are Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial processing of a specimen into the lab's system, which includes confirming that the specimen was properly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and filling in any missing information not included by an electronic custody chain.
Screening entails an initial rapid assessment for drug abuse. While Screening is an economical approach to exclude drug usage in most samples, a positive screen necessitates confirmation for legal admissibility. Any presumptively positive samples require further confirmation.
Following a presumptive positive in the Screening phase, more hair is extracted from the initial sample and prepped for Extraction. Here, drugs are extracted from hair at much lower concentrations than in alternatives (e.g., urine or oral fluid), explaining why hair drug testing is the most challenging to conduct.
Confirmation of any positive screen is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples labeled as presumptive positives are cleaned before confirmation as necessary. The complete laboratory workflow from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
