Hair testing has evolved into an effective method for identifying drug and alcohol consumption. This technique analyzes hair, which captures long-term drug and alcohol history by trapping biomarkers within its growing strands. When sourced close to the scalp, hair can identify substance use for a period up to roughly three months. Hair collection is straightforward, difficult to tamper with, and simple to transport.
To achieve an optimal sample for testing and verification, a 1.5-inch segment comprising approximately 200 hair strands, akin to a #2 pencil's thickness, should be taken closest to the scalp, amounting to 100mg of hair. For EtG, additional tests, and/or screens exceeding 10 panels, 150mg of the sample is suggested. Measuring the sample's weight on a jeweler's scale is advised. Should scalp hair be unavailable, a similar quantity of body hair may be used. When discussing head hair, we imply scalp hair exclusively, whereas body hair encompasses all alternative hair types (e.g., facial, axillary).
Process Overview
The lab processing for a drug test result involves four principal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the sample's entry phase into a laboratory system, ensuring it has been appropriately sealed and transported, assigning it a unique LAN (Laboratory Accessioning Number), and completing any supplementary data input absent from an electronic chain of custody system.
Screening executes a preliminary, rapid assessment for drug abuse. Although Screening is an economical method for determining drug abstinence in most samples, positive findings necessitate subsequent confirmation for court admissibility. Any samples yielding a tentative positive during Screening must undergo a secondary validation.
In instances where a sample tests positively in the Screening phase, additional hair is extracted from the original sample and readied for Extraction. This process retrieves drugs from hair at concentrations much smaller than other methodologies (e.g., urine or oral fluid), rendering hair drug screening the most complex methodology to execute.
Positive Screening outcomes are verified using GC/MS, GC/MS/MS, or LC/MS/MS. Any conditional positive samples are meticulously cleaned before confirmation, as required. The entire lab process spanning Accessioning to Confirmation is scrutinized in alignment with both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 standards accreditation.
