Hair analysis is now regarded as an influential method for detecting drug and alcohol consumption. Hair captures a prolonged record of alcohol and other substances by embedding biomarkers in the strands of the growing hair. When obtained from close to the scalp, it can offer a detection window for alcohol and other substances extending up to about 3 months. Hair collection is straightforward, relatively resistant to alteration, and simple to transport.
A 1.5-inch section of roughly 200 hair fibers (similar in size to a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal sample size for screening and confirmation procedures. For EtG, supplemental tests, and/or those beyond 10 panels, a specimen of 150mg is advised. We suggest evaluating the specimen on a jeweler’s scale. Should scalp hair be absent, a proportional quantity of body hair is permissible. By head hair, we mean scalp hair exclusively. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The four critical phases in the lab processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial handling of a specimen into a lab’s records. This stage includes ensuring the sample was properly sealed and shipped, allocating a random LAN (Laboratory Accessioning Number), and completing any outstanding data input not supplied by an electronic chain of custody framework.
Screening denotes an immediate, preliminary examination for drugs of abuse. While Screening offers a budget-friendly means to eliminate drug involvement for most samples, a positive result necessitates confirmation for courtroom reliability. Samples suggesting positivity in Screening require subsequent verification.
If a sample suggests positivity during Screening, additional hair is extracted from the original specimen and prepared for Extraction. In Extraction, drugs are retrieved from hair at significantly diminished concentrations compared to other techniques (e.g., urine or oral fluid), signifying hair drug analysis as one of the most challenging techniques to execute.
Validation of any positive screening result is implemented via GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating positive results undergo washing before confirmation if necessary. The complete laboratory workflow from Accessioning to Confirmation undergoes examination per both the CAP (College of American Pathologists) Hair categorization and conformity to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Though often termed "hair follicle tests", the analysis focuses on the hair strand rather than the follicle beneath the scalp.
