Hair examinations have emerged as a vital method for identifying drug and alcohol consumption. Hair offers an extended timeline for alcohol and drug detection by capturing biomarkers within the fibers of the hair as it grows. When harvested near the scalp, hair can demonstrate a detection timeframe of up to roughly three months for alcohol and drugs. Hair collection is straightforward, relatively hard to tamper with, and convenient to transport.
A sample of 1.5 inches consisting of about 200 strands of hair (approximately the thickness of a #2 pencil) near the scalp yields 100mg, which is perfect for both screening and confirmation purposes. For EtG add-ons or tests exceeding 10 panels, 150mg of the sample is suggested. It's advisable to weigh the sample using a jeweler’s scale. If scalp hair is missing, a similar quantity of body hair can be used. By head hair, we mean strictly scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The four fundamental stages in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial entry of a sample into a laboratory’s system. This phase verifies the sample is sealed and shipped correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry not supported by an electronic chain of custody system.
Screening is an initial rapid assessment for drug abuse. While it is a cost-efficient way to dismiss drug use in most samples, confirming a positive screen is essential for court admissibility. Samples indicated as presumptively positive in Screening necessitate secondary confirmation.
If Screening results suggest a presumptive positive, additional hair is extracted from the original sample for Extraction. During this phase, drugs are extracted from hair at concentrations much lower than other methods (ex. urine or oral fluid), making hair drug screening the most challenging methodology to execute.
The Confirmation of any Screening positive is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if required. The complete laboratory procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation.
