Hair testing is now considered an effective method for identifying drug and alcohol consumption. Hair captures a long-term record of substances by securing biomarkers within the strands as they grow. When sampled near the scalp, hair can reveal substance use for up to around three months. It is straightforward to collect, somewhat resistant to tampering, and simple to transport.
A 1.5-inch segment of approximately 200 strands of hair, roughly the girth of a #2 pencil, near the scalp provides 100mg of hair, which is optimal for analysis. For EtG, additional tests, and tests exceeding 10 panels, 150mg is preferred. We suggest measuring the sample with a jeweler’s scale. If scalp hair is not accessible, a comparable amount of body hair is acceptable. In cases concerning head hair, we exclusively mean scalp hair. Body hair encompasses all other varieties (face, axillary, etc.).
Process Overview
The laboratory processing of a drug test result comprises four fundamental stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially catalogued into a lab's system. This step includes verifying the sample's secure seal and proper shipment, issuing a random LAN (Laboratory Accessioning Number), and finalizing any missing data entry not provided by an electronic chain of custody.
Screening is a preliminary check for substance abuse. Although Screening economically rules out drug use for most samples, any positive findings must be verified for legal acceptance. Samples marked as presumptively positive in Screening require a follow-up confirmation.
For samples flagged presumptively positive in Screening, additional hair is extracted from the original sample for the Extraction phase. Here, substances are removed from hair at much lower levels compared to other methods (e.g., urine or oral fluid), which makes hair drug screening the most complex technique to administer.
Any positive Screening result is further validated by GC/MS, GC/MS/MS, or LC/MS/MS. Before Confirmation, all presumptively positive samples are cleansed as necessary. The complete lab procedure from Accessioning to Confirmation undergoes evaluation under both the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation standards.
