Hair analysis has increasingly become recognized as an effective method for identifying drug and alcohol consumption. Hair serves as a record for long-term intake of alcohol and drugs by embedding biomarkers within the hair strand as it grows. When hair is taken near the scalp, it can reveal an approximate 3-month detection period for alcohol and drugs. Hair is straightforward to gather, relatively challenging to tamper with, and convenient to transport.
A 1.5-inch portion consisting of roughly 200 hair strands (similar to a #2 pencil size) near the scalp yields 100mg of hair, which is the optimal sample size for testing and verification. For EtG, additional tests, and/or tests beyond 10 panels, 150mg of hair is advised. It’s suggested to use a jeweler's scale for measuring the specimen. If scalp hair isn’t available, a corresponding quantity of body hair can be taken. When we mention head hair, we mean scalp hair specifically. Body hair denotes all other types (facial, axillary, etc.).
Process Overview
The basic process steps in a laboratory drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the introductory handling of a sample within a lab’s system. It includes checking that the sample was appropriately sealed and dispatched, assigning a distinct LAN (Laboratory Accessioning Number), and performing any additional data entry not already noted in an electronic chain of custody system.
Screening represents a preliminary assessment for drugs of abuse. While it’s a budget-friendly means to exclude drug usage in most samples, a positive screening necessitates confirmation for court acceptability. Any samples indicating presumptive positivity in Screening demand subsequent validation.
Should a sample yield presumptive positivity during Screening, extra hair is extracted from the original sample and readied for Extraction. Here, drugs are removed from hair at concentrations significantly lower than other techniques (e.g., urine or oral fluid), which is why hair drug screening is the most complex methodology to execute.
Any positive screen result undergoes Confirmation utilizing GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are cleansed beforehand for confirmation purposes. The entire lab process from Accessioning to Confirmation falls under scrutiny by both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation standards.
