Hair analysis is increasingly recognized as an effective means for spotting drug and alcohol consumption. It provides an extended timeline of exposure by capturing biomarkers within the hairs as they grow. When sampled near the scalp, hair can detect alcohol and drugs for around a 3-month span. Hair collection is straightforward, hard to tamper with, and convenient to transport.
A sample of 1.5 inches with approximately 200 hair strands (comparable in size to a #2 pencil) from the scalp can provide 100mg of hair, which is optimal for both screening and confirmation. For EtG and expanded panels beyond 10, 150mg of hair is suggested. It's advisable to use a jeweler’s scale for weighing the sample. If head hair isn’t available, an equivalent volume of body hair can be used. Here, head hair specifically denotes scalp hair. Body hair encompasses all other types like facial or axillary hairs.
Process Overview
The four essential phases in processing drug testing results are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves integrating a sample into the lab’s system by checking proper sealing and shipment, assigning a LAN (Laboratory Accessioning Number), and completing additional data entries not covered by an electronic chain of custody.
Screening offers a preliminary assessment for substance abuse. While it's a cost-efficient method for ruling out drug consumption in most samples, a positive screening requires confirmation for legal admissibility. Presumptive positives necessitate secondary confirmation.
When a sample tests positive during Screening, additional strands are collected for Extraction. This phase extracts drugs from hair at much lower concentrations compared to other methods (e.g., urine, oral fluid), underscoring the complexity of hair drug testing.
Confirmations of positive screenings are executed via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives undergo washing prior to confirmation if necessary. The process from Accessioning through Confirmation is scrutinized under CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
