Hair analysis is becoming a significant method for detecting the use of alcohol and drugs. Hair captures a prolonged history of alcohol and drugs by embedding biomarkers within its fibers as it grows. A sample taken near the scalp offers approximately a three-month period for detecting alcohol and drugs. Hair is easy to collect, resistant to tampering, and simple to transport.
For an adequate sample used for both screening and confirmation, a 1.5-inch segment consisting of about 200 strands (similar in size to a #2 pencil) from close to the scalp will provide 100mg of hair. For EtG, additional tests, and those exceeding 10 panels, a 150mg specimen is suggested. We recommend using a jeweler’s scale for precise weighing. If scalp hair is unobtainable, equivalent body hair is acceptable. "Head hair" refers exclusively to scalp hair, while "body hair" encompasses hair from other areas (e.g., facial, axillary).
Process Overview
The laboratory procedure for processing a drug test result comprises four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial steps of entering a sample into a laboratory system, which involves checking that the sample was properly sealed and shipped, assigning it a unique LAN (Laboratory Accessioning Number), and finalizing any additional data entry absent from the electronic chain of custody.
Screening performs a preliminary assessment for the presence of drugs. While Screening is an economical approach to exclude drug use from most samples, confirmed results are necessary for legal admissibility. Any samples showing presumptive positivity during Screening compel further confirmation.
In cases of a presumptively positive outcome from Screening, additional hair is extracted from the original sample and subjected to Extraction. This phase extracts drugs from hair at notably lower concentrations compared to methods such as urine or oral fluid testing, making hair drug testing the most challenging method to execute.
Positive results from Screening undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results are cleansed before confirmation when required. The entire process, from Accessioning to Confirmation, undergoes a review according to the CAP (College of American Pathologists) Hair standards and accreditation under ISO / IEC 17025.
