Hair testing is widely recognized as an effective method for detecting drug and alcohol consumption. Hair acts as a long-term record for alcohol and substances by capturing biomarkers within the fibers of the hair strand as it grows. When taken from near the scalp, hair offers around a 3-month detection period for alcohol and substances. Hair collection is straightforward, relatively hard to tamper with, and convenient for transport.
A sample size of 1.5 inches consisting of approximately 200 hair strands (roughly the thickness of a #2 pencil) nearest to the scalp provides 100mg of hair, which is ideal for testing and verification. For EtG, additional tests, and/or panels over 10, it is advisable to use 150mg of the sample. We suggest using a jeweler’s scale to weigh the sample. If scalp hair is not available, a similar quantity of body hair can be used. By head hair, we mean only scalp hair. Body hair includes all other types (facial, axillary, etc.).
Process Overview
The primary four steps in the laboratory processing of a drug screening result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the sample’s initial entry into the lab’s system. This step involves ensuring the sample was correctly sealed and shipped, assigning a random Laboratory Accessioning Number (LAN), and completing any data entry missing from an electronic chain of custody system.
Screening is a preliminary check for substance abuse. While Screening is a budget-friendly way to dismiss drug usage in most cases, a positive screen must be validated to stand in court. Any samples with a presumptive positive result in Screening need additional confirmation.
For samples that are presumptively positive during Screening, extra hair is taken from the initial sample and prepared for Extraction. Here, drugs are removed from hair at a much lower concentration than other methods (e.g., urine or oral fluid), explaining why hair drug screening is considerably challenging.
Confirmation for any positive screening result is done using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo washing before confirmation as needed. The complete laboratory procedure from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
