The recognition of hair testing as a robust method for identifying alcohol and drug use has increased. This is because hair captures biomarkers within the fibers of the growing strand, offering an extended record of consumption. When sampled close to the scalp, hair reveals drug and alcohol intake for a span of nearly three months. The collection process is straightforward, making it less prone to tampering, and it's conveniently shipped.
Collecting a 1.5-inch section consisting of roughly 200 hair strands (similar in diameter to a #2 pencil) can yield 100mg of hair, which is optimal for both initial testing and validation. For EtG, supplementary tests, or any panels exceeding 10, it's advisable to gather 150mg of the sample. It's ideal to measure the sample weight using a jeweler’s scale. When scalp hair is not accessible, a corresponding amount of body hair is sufficient. Specifically, head hair refers to scalp hair, while body hair includes other types like facial or axillary hair.
Process Overview
The laboratory procedure for processing drug test results encompasses four key phases: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is entered into the laboratory system. This step ensures the sample is accurately sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and addresses any remaining data requirements not captured by an electronic custody system.
Screening entails an elementary examination for drugs of abuse. Though screening effectively eliminates drug presence in most samples at a reduced cost, a positive indication demands further confirmation to stand in legal contexts. Samples flagged as presumptive positives during Screening will require additional confirmation.
Samples that test positively in the Screening phase undergo further processing in Extraction. At this stage, drug compounds are retrieved from hair at a significantly lower concentration than other methods like urine or oral fluids, underscoring the complexity of performing hair drug tests.
Confirmation of any positive detection from screening utilizes GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo washing prior to confirmation as necessary. The complete laboratory cycle from Accessioning to Confirmation is evaluated following both the CAP (College of American Pathologists) standards and ISO / IEC 17025 accreditation.
