Hair tests have become recognized as an effective means for identifying drug and alcohol consumption. Hair offers a chronic timeline of substance use by capturing biomarkers within the developing hair fibers. When taken near the scalp, hair can give up to a 3-month detection period for drugs and alcohol. Hair collection is straightforward, challenging to tamper with, and convenient to transport.
A sample measuring 1.5 inches with around 200 hair strands (similar in size to a #2 pencil) closest to the scalp will yield 100mg of hair, the recommended size for assessment and confirmation. For EtG, additional tests, and/or panels exceeding 10, 150mg of the sample is advised. We propose using a jeweler’s scale to weigh the sample. If scalp hair isn't available, a comparable amount of body hair may be gathered. By head hair, we mean scalp hair solely, whereas body hair includes other hair types (facial, axillary, etc.).
Process Overview
The laboratory steps in processing a drug test result encompass Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the sample's initial integration into the laboratory system. This covers confirming that the sample was sealed and dispatched appropriately, assigning a unique LAN (Laboratory Accessioning Number), and completing any outstanding data input not recorded by an electronic chain of custody system.
Screening involves a preliminary assessment for substance abuse. Although Screening is an economical method to dismiss drug usage in most samples, a positive outcome requires confirmation for legal acceptance. All samples that indicate a potential positive in Screening necessitate additional confirmation.
When a sample suggests a potential positive during Screening, additional hair is extracted from the original sample and prepared for Extraction. In this phase, substances are isolated from hair at significantly lesser concentrations compared to other approaches (e.g., urine or oral fluid), making hair drug detection the most complex method to execute.
Verification of any positive Screening outcome is done using GC/MS, GC/MS/MS, or LC/MS/MS. All potentially positive samples are cleansed before confirmation if necessary. The entire lab process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair guidance and accreditation to ISO / IEC 17025 standards.
