The utilization of hair testing has emerged as an effective method for identifying the consumption of drugs and alcohol. Hair captures a comprehensive history of alcohol and other drug use by encapsulating biomarkers within the strands as they grow. When taken from the scalp, hair has the capability to reveal drug and alcohol use over an approximate period of 3 months. Hair is straightforward to collect, difficult to tamper with, and convenient to transport.
A 1.5-inch sample, consisting of roughly 200 hairs (comparable to a #2 pencil's width) near the scalp, yields 100mg of hair, which is ideal for both screening and confirmation. For situations involving EtG, additional testing, or when the panel exceeds 10 tests, a 150mg sample is advisable. Using a jeweler’s scale to weigh the specimen is suggested. If scalp hair is inaccessible, an equivalent mass of body hair can be used. By head hair, we specifically mean scalp hair. Body hair encompasses other hair varieties (such as facial, axillary, etc.).
Process Overview
The laboratory procedure for processing a drug test sample encompasses four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the step where the sample initially enters the laboratory system. This entails confirming that the sample was properly sealed and shipped, generating a random LAN (Laboratory Accessioning Number), and completing any extra data entry absent in an electronic chain of custody system.
Screening refers to the preliminary quick analysis for drugs. Screening offers a cost-effective means to exclude drug use for most samples, although a positive result requires confirmation for legal admissibility. Samples that initially test positive in Screening necessitate a secondary confirmation process.
In cases where a sample indicates a positive result during the Screening stage, additional hair is drawn from the original sample for the Extraction phase. Here, drugs are isolated from hair at notably lower concentrations than found in other testing methodologies (such as urine or oral fluid), underscoring the complexity of hair drug testing.
Confirmed positive results are validated using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo washing as necessary before confirmation. The comprehensive laboratory process, from Accessioning through to Confirmation, adheres to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
