Hair analysis has emerged as an instrumental approach for identifying drug and alcohol consumption. The hair captures a prolonged record of alcohol and other substances, encapsulating biomarkers within its growing fibers. When acquired near the scalp, hair can reveal drug and alcohol use for approximately three months. Collection is straightforward, tampering is relatively challenging, and shipping is uncomplicated.
A 1.5-inch segment of around 200 hair strands (comparable to a #2 pencil) nearest to the scalp will provide 100 mg of hair, the preferred amount for both screening and confirmation. For EtG, additional assays, and assessments involving more than 10 panels, 150 mg of hair is suggested. It is advisable to weigh the hair using a jeweler’s scale. If scalp hair is not accessible, an equivalent amount of body hair can be utilized. "Head hair" specifically denotes scalp hair, whereas "body hair" pertains to all other variants (facial, axillary, etc.).
Process Overview
The laboratory procedure in drug testing encompasses four principal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary introduction of the sample into the laboratory's system. This step includes ensuring the sample’s seal and shipment were correctly managed, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data input absent from an electronic chain of custody system.
Screening provides an initial rapid assessment for drug abuse markers. While Screening is a cost-friendly method to exclude drug usage in most samples, outcomes indicating drug presence must undergo Confirmation to be deemed valid for court proceedings. Samples that have a positive indication during Screening necessitate further verification.
If Screening yields a positive indication, additional hair is drawn from the original sample for Extraction preparation. During this phase, drugs are isolated from hair at significantly lower concentrations than observed in urine or oral fluid, making hair drug testing a challenging method to conduct.
Confirmation follows for any screening results indicating positivity and is performed using either GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumed positive samples undergo a washing process before Confirmation. Each phase from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair specific standards and the ISO / IEC 17025 accreditation requirements.
Advantages of hair drug testing:
Limitations:
Note: The term "hair follicle tests" is commonly used, but the analysis focuses on the hair strand rather than the follicle beneath the scalp.
