Hair analyses have gained recognition as a robust method for identifying drug and alcohol consumption. The strands of hair harbor markers of alcohol and drugs over time by embedding them within the growing fibers. When sourced near the scalp, hair can show substance use history for a period extending up to roughly three months. Hair is straightforward to collect, challenging to tamper with, and convenient for shipping.
A 1.5-inch length comprised of about 200 hairs (approximately the size of a #2 pencil) from the scalp will yield 100mg of hair, which is ideal for both screening and confirmation. For EtG, additional analysis, or tests exceeding 10 panels, a specimen amount of 150mg is advised. It is suggested to measure the specimen on a jeweler’s scale. If scalp hair cannot be obtained, a similar quantity of body hair may be used. References to head hair specifically indicate scalp hair. Body hair encompasses other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result includes four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial integration of a sample into a lab's processing system. This process involves confirming that the sample was appropriately sealed and sent, assigning a unique LAN (Laboratory Accessioning Number), and completing any essential data entry absent from an electronic chain of custody system.
Screening consists of an initial rapid evaluation for illicit substances. Screening is a cost-effective manner to dismiss drug usage in most specimens; however, a screen yielding a positive requires confirmation for legal admissibility. Any specimens that show a presumptive positive in Screening need secondary verification.
Should a specimen present a presumptive positive during Screening, additional hair is retrieved from the initial sample and prepared for Extraction. In this phase, drugs are isolated from hair at a much lower concentration compared with other measures (e.g., urine or oral fluid), rendering hair drug screening the most challenging method to perform.
Confirmation of any positive identified in Screening is executed using GC/MS, GC/MS/MS or LC/MS/MS technology. All samples preliminarily positive undergo a wash as needed before confirmation. The entirety of the lab procedure from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
