Hair analysis is increasingly regarded as a significant method for identifying drug and alcohol consumption. Hair captures a prolonged history of alcohol and drug intake by securing biomarkers within the strands. Sampling hair near the scalp can offer a detection span of roughly three months for alcohol and drugs. Hair samples are easy to gather, hard to tamper with, and convenient to transport.
A sample measuring 1.5 inches with approximately 200 hair strands (comparable to a #2 pencil) nearest the scalp will yield 100mg, which is the optimal amount for testing. For EtG, additional tests, or panels exceeding 10, it is advisable to use 150mg. Using a jeweler’s scale to weigh the sample is recommended. Should scalp hair be inaccessible, equivalent body hair may be utilized. References to head hair specifically denote scalp hair, while body hair considers all other types (facial, axillary, etc.).
Process Overview
The core stages in laboratory processing for drug test results involve Accessioning, Screening, Extraction, and Confirmation.
Accessioning comprises the initial sample processing into a lab’s system. It involves ensuring the sample's seal and shipment integrity, allocating a unique LAN (Laboratory Accessioning Number), and finalizing any incomplete data entry not managed by an electronic chain of custody system.
Screening constitutes a preliminary swift evaluation for substance abuse. Although Screening is economical for excluding drug use in most samples, a positive outcome mandates a confirmation for legal acceptance. Presumptive positive results in Screening necessitate an additional confirmation process.
For samples with presumptive positives at the Screening phase, additional hair from the initial sample is extracted for further analysis. This stage involves extracting drugs from hair at significantly lower concentrations than other methods (like urine or oral fluids), signifying the complexity of hair drug screening testing.
Confirmation for any positive Screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positives are cleansed before confirmation as required. The complete lab procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
