Hair strand analyses have emerged as an effective method for detecting substance and alcohol consumption. The hair captures biomarkers within its fibers, offering a prolonged summary of substance use. When cut near the scalp, the hair can provide an indication of drug and alcohol history for roughly three months. The collection process is straightforward, with moderate difficulty in tampering, and the samples can be easily mailed.
A sample measuring 1.5 inches, consisting of approximately 200 hair strands (equivalent to a #2 pencil thickness), yields 100mg, optimal for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, it's advisable to have 150mg of the sample. We suggest using a jeweler’s scale for precise measurement. Should scalp hair be unavailable, similar quantities of body hair are acceptable. References to head hair imply only scalp hair, whereas body hair encompasses all other variants (such as facial or underarm hair).
Process Overview
The lab processing for a drug test encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preliminary integration of the specimen into the lab's framework, which includes verifying proper seal and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any remaining information not covered by an electronic chain of custody system.
Screening serves as a preliminary assessment for substance misuse. Although it's a low-cost approach for dismissing cases of drug consumption among most samples, any positive screen must undergo confirmation for court validity. Samples that screen positively presumptively require further verification.
When a sample screens positively in the initial assessment, additional hair is extracted from the sample and prepared for the Extraction phase. This involves isolating drugs from the hair at a lower concentration compared to other methods (e.g., urine or saliva), indicating why it's the most challenging method to conduct.
A confirmed positive from screening is validated using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples are cleansed before confirmation as necessary. The complete laboratory workflow from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 accreditation.
