Hair analysis is recognized as an effective technique for identifying drug and alcohol consumption. By encasing biomarkers within the strands, hair offers an extended timeline of substance exposure. If collected from near the scalp, it can extend the detection window for up to three months. Hair is easy to sample, challenging to tamper with, and simple to transport.
A 1.5-inch segment consisting of roughly 200 hair strands (comparable to a #2 pencil) procures 100mg of hair, which is the preferred sample volume for evaluation and verification. For additional tests like EtG or those requiring more than 10 panels, a 150mg sample is advised. Utilizing a jeweler's scale for measurement is suggested. If head hair cannot be obtained, equivalent body hair is an alternative. Reference to head hair implies only scalp hair, while body hair includes other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test involves the steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the inception stage where a sample is integrated into the lab's system. It entails confirming that the sample was intact and correctly sent, assigning it a unique LAN (Laboratory Accessioning Number), and completing additional data entry absent in an electronic custody system.
Screening is a preliminary assessment for illicit substances. Though Screening provides a cost-efficient method to discount drug presence in most samples, a screen showing positive results requires confirmation for judicial admissibility. Samples tentatively positive in Screening necessitate further verification.
Upon a presumptive positive outcome in Screening, additional hair from the original sample is readied for Extraction. Drugs are isolated from hair at much subtler concentrations than other methods (such as urine or oral fluids), making hair drug analysis particularly challenging to execute.
Verification of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating probable positivity are cleansed before confirmation where necessary. The full laboratory routine from Accessioning to Verification is audited based on the CAP (College of American Pathologists) Hair recognition and ISO / IEC 17025 certification.
