Hair analysis is increasingly recognized as an effective means for identifying drug and alcohol consumption. Hair offers an extended overview of substance use by capturing biomarkers within the thread of the hair as it grows. When obtained near the scalp, it can reveal up to a 3-month timeline for detecting alcohol and other substances. Hair collection is straightforward, relatively hard to tamper with, and simple to transport.
A 1.5-inch segment comprising approximately 200 hair strands (roughly the width of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimum amount for both initial testing and confirmation. For EtG, additional tests, and/or when conducting tests exceeding 10 panels, a 150mg sample is advised. We suggest weighing the sample with a jeweler’s scale. In cases where scalp hair is missing, an equal portion of body hair may be gathered. When mentioning head hair, we specifically mean scalp hair. Body hair denotes all other types (facial, axillary, etc.).
Process Overview
The primary components involved in analyzing a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial setup of a sample within the laboratory’s database. This includes ensuring the sample was properly sealed and sent, assigning a unique LAN (Laboratory Accessioning Number), and filling in any missing data not supplied by an electronic chain of custody system.
Screening entails a preliminary examination for substance misuse. While Screening is a budget-friendly approach to eliminate drug use in most samples, a positive result must be confirmed to hold up legally. All samples appearing positive in Screening require further confirmation.
If a sample appears positive in the Screening phase, additional hair is extracted from the original specimen and prepped for Extraction. During Extraction, substances are removed from hair at significantly lower concentrations than other methods (like urine or saliva), making hair drug screening the toughest method to conduct.
Confirmation of any screening positive is accomplished using GC/MS, GC/MS/MS or LC/MS/MS. All samples deemed presumptive positive undergo washing before confirmation if necessary. The full lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation.
