Hair tests have emerged as an effective means for identifying drug and alcohol consumption. Hair captures long-term consumption patterns by embedding biomarkers within its strands. A sample collected near the scalp can reveal drug and alcohol usage over a period of up to three months. Hair collection is straightforward, comparatively hard to tamper with, and easy to transport.
A 1.5-inch segment of about 200 hairs (akin to the width of a number two pencil) closest to the scalp yields roughly 100mg, which is optimal for initial and confirmatory testing. For EtG, additional tests, or panels exceeding 10, 150mg is recommended. It's advisable to weigh specimens using a jeweler's scale. If scalp hair cannot be obtained, a similar amount of body hair may be used. "Head hair" specifically means scalp hair, while "body hair" encompasses all other hair types like facial and axillary.
Process Overview
The key stages in lab processing of drug test results are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves initially logging the sample into the lab system. This includes ensuring the sample was correctly sealed and transported, assigning it a unique LAN (Laboratory Accessioning Number), and entering any additional data not captured by an electronic chain of custody system.
Screening involves a preliminary assessment for illegal substances. Although cost-efficient for negating drug presence in most cases, results must be confirmed to be valid in legal settings. Any samples showing potential drug presence in Screening require detailed confirmation.
If Screening suggests a positive result, additional hair from the sample is readied for Extraction. Here, drug elements are pulled from hair at lower concentrations than alternatives like urine or saliva, highlighting the complexity of hair drug testing.
Positive results are verified with GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives are washed before confirmation if needed. The process from Accessioning to Confirmation undergoes review according to CAP (College of American Pathologists) Hair criteria and complies with ISO / IEC 17025 standards.
