Hair analysis has emerged as a potent method for identifying drug and alcohol consumption. Hair offers an extended history of alcohol and drug intake by embedding biomarkers within the strands of hair as they grow. When collected near the scalp, hair can offer about a 3-month window of detection for alcohol and drugs. Hair is easy to gather, relatively resistant to tampering, and convenient to transport.
A 1.5-inch segment consisting of roughly 200 strands of hair (about the size of a #2 pencil) closest to the scalp will provide 100mg of hair, which is the optimal sample for both screening and confirmation. For EtG, additional tests, and/or analyses exceeding 10 panels, 150mg of hair is advised. Using a jeweler’s scale for weighing the specimen is recommended. If scalp hair is not an option, an equivalent quantity of body hair can be taken. When specifying head hair, this refers to scalp hair solely. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial processing of a sample into the lab's system. It involves verifying that the sample was appropriately sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry otherwise absent in an electronic chain of custody system.
Screening entails an initial rapid assessment for drug substances. While Screening is a cost-efficient means to exclude drug usage on most samples, a positive screen requires confirmation to be valid in court. Samples flagged as presumptively positive during Screening necessitate a secondary validation process.
If a specimen tests presumptively positive in the Screening phase, additional hair is retrieved from the initial sample for Extraction. In Extraction, drugs are isolated from hair at much lower concentrations than other methods (ex. urine or oral fluid), highlighting why hair drug screening is considered the most challenging methodology to undertake.
Confirmation for any positive screening result is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumptively positive are washed prior to confirmation if necessary. The entire laboratory workflow from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation in accordance with ISO / IEC 17025 standards.
