Hair analysis has emerged as an effective method for identifying substance and alcohol consumption. The strands of hair capture long-term markers of alcohol and drugs in the fibers as it grows. When collected near the scalp's base, hair can provide an approximately 3-month timeframe for detecting alcohol and other substances. It is straightforward to gather, relatively hard to tamper with, and simple to transport.
A 1.5-inch segment of about 200 hairs (roughly the thickness of a #2 pencil) adjacent to the scalp will yield 100mg of hair, which is the perfect amount for analysis and confirmation. For EtG, extra panels, and/or tests beyond 10 panels, 150mg of the sample is suggested. We suggest measuring the sample on a jeweler’s scale. If head hair is absent, a comparable amount of body hair can be used. When mentioning head hair, it refers only to scalp hair. Body hair includes all other hair types (like facial, axillary, etc.).
Process Overview
The laboratory analysis of a drug test result consists of four major steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of the sample within the lab’s system. This involves confirming the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry complements lacking in an electronic chain of custody system.
Screening is a quick preliminary check for the presence of drugs. While Screening offers a cost-effective method to eliminate drug usage for most samples, a positive result requires confirmation to be legally valid. Any samples showing a presumptive positive in Screening need further verification.
Should a sample show a presumptive positive at the Screening stage, more hair is taken from the original sample and prepared for Extraction. During Extraction, drugs are isolated from hair at significantly reduced concentrations compared to other methods (e.g., urine or oral fluid), thus making hair drug analysis one of the most complex methods to conduct.
Confirmation of any positive Screening result is conducted using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positive results are cleaned before confirmation as needed. The complete lab process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair criteria and the accreditation under ISO / IEC 17025 standards.
