Hair analysis is regarded as an effective method for identifying drug and alcohol consumption. Hair presents a long-term record of substance intake by embedding biomarkers within the fibers of the hair as it grows. When cut near the scalp, hair can reveal substance use over an approximately 3-month timeframe. Hair collection is straightforward, challenging to tamper with, and can be shipped easily.
A segment of hair measuring 1.5 inches, comprising roughly 200 strands (comparable in size to a #2 pencil) near the scalp, will yield 100mg of hair, which is optimal for testing and verification. For EtG, additional screenings, and/or testing beyond 10 panels, 150mg is advisable. It's best to use a jeweler’s scale to weigh the collected sample. Should scalp hair be unavailable, an equivalent volume of body hair may be gathered. Here, head hair refers solely to scalp hair; body hair encompasses all other types (such as facial and axillary hair).
Process Overview
The principal stages involved in lab analysis of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning denotes the first phase of incorporating a sample into the lab’s tracking system, ensuring it was sealed and sent accurately, assigning a random Laboratory Accessioning Number (LAN), and completing any extra data entry not included through an electronic chain of custody process.
Screening serves as an initial check for drugs. While Screening is an economical way to exclude drug consumption in most samples, positive results must be verified to be valid in legal settings. All samples that test positive in Screening necessitate a confirmatory test.
If the Screening process indicates a presumptive positive, additional hair is utilized from the initial sample and readied for Extraction. This step extracts drugs from hair at significantly lower concentrations compared to other methods (e.g., urine or saliva), which is why hair drug testing is among the most complex techniques.
To confirm any positive results from Screening, procedures like GC/MS, GC/MS/MS or LC/MS/MS are employed. All samples that show presumptive positives are cleansed before confirmation as needed. The comprehensive lab cycle from Accessioning through Confirmation is conducted under the College of American Pathologists (CAP) Hair guidelines and accredited against ISO / IEC 17025 criteria.
