The technique of hair testing has emerged as a significant resource for identifying drug and alcohol consumption. Hair captures a prolonged history of alcohol and drug use by embedding biomarkers within its fibers as it grows. When gathered near the scalp, hair offers a detection timeframe for substances that can extend up to roughly three months. It's easy to obtain, relatively resistant to tampering, and straightforward to transport.
A hair sample measuring 1.5 inches, consisting of approximately 200 strands (comparable to a #2 pencil's thickness) nearest the scalp, will yield roughly 100mg, which is optimal for both screening and confirming results. For EtG, additional tests, or tests exceeding 10 panels, a 150mg sample is advised. Using a jeweler's scale for weighing is recommended. If no scalp hair is accessible, a similar amount of body hair can be collected. When mentioning head hair, it specifically means scalp hair. Body hair includes all other categories (like facial, axillary, etc.).
Process Overview
The process of laboratory handling of a drug test outcome comprises four principal steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes its initial processing into the lab’s system. This step ensures the sample was adequately sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and completes any missing data entry absent from an electronic chain of custody system.
Screening entails a preliminary rapid test for drugs of concern. While it’s economical for eliminating the possibility of drug involvement in most cases, a positive screen must be verified to be court-admissible. Samples that show presumptive positivity during Screening require subsequent verification.
Should a specimen show presumptive positivity during Screening, additional hair is extracted from the initial sample and readied for Extraction. Drugs are isolated from hair at much lower concentrations compared to other methodologies (like urine or oral fluid), making hair drug tests the most complex to execute.
Confirmation of positive screening outcomes utilizes GC/MS, GC/MS/MS, or LC/MS/MS. All samples flagged as presumptive positive are cleansed before confirmation, as necessary. The entire laboratory process, from Accessioning to Confirmation, receives oversight under the CAP (College of American Pathologists) Hair guidelines alongside accreditation to ISO / IEC 17025 criteria.
