Hair testing is now recognized as a significant method for identifying drug and alcohol consumption. Hair acts as a reservoir for long-term drug and alcohol history by embedding biomarkers within the fibers as the hair grows. When cut near the scalp, it can offer a detection period of up to roughly three months for alcohol and drugs. Hair collection is straightforward, hard to tamper with, and simple to transport.
An ideal sample for screening and confirmation involves a 1.5-inch segment of around 200 hair strands (comparable to the diameter of a #2 pencil) nearest to the scalp, equaling 100mg of hair. For testing EtG, add-ons, or beyond 10 panels, 150mg is advisable. It is recommended to weigh the sample using a jeweler’s scale. In cases where scalp hair is not present, a similar quantity of body hair can be utilized. Note that head hair specifically pertains to scalp hair, whereas body hair encompasses other types (face, axillary, etc.).
Process Overview
The procedure for processing a drug test result in the laboratory involves four critical steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is first processed into a lab’s system. This step includes verifying the sample’s seal and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary data entry not covered by an electronic chain of custody.
Screening entails an initial rapid evaluation for substances of abuse. While this is an economical method to eliminate drug use for most samples, a positive result in Screening necessitates confirmation for legal admissibility. Any samples returning a presumptive positive in Screening must be confirmed through a secondary process.
Should a sample yield a presumptive positive during Screening, an additional portion of hair is extracted from the original sample for further Examination. Here, drugs are isolated from hair at much lower levels than other techniques (e.g., urine or oral fluid), establishing hair drug screening as the most challenging process to conduct.
Confirmation of positive Screening outcomes is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all samples showing presumptive positivity are cleansed as required. The comprehensive procedure from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair specification and the ISO / IEC 17025 accreditation.
