Regarded as an effective method, hair testing is instrumental for identifying substance and alcohol consumption. Hair acts as a long-term record by embedding biomarkers within the fibers of the hair strand as it grows. When cut near the scalp, hair can show evidence of drug and alcohol use for up to three months. Collecting hair samples is straightforward, challenging to tamper with, and easy to transport.
A 1.5-inch length consisting of roughly 200 strands of hair (approximately matching the size of a #2 pencil) from close to the scalp will yield 100mg of hair, which is the perfect quantity for screening and verifying results. For EtG, additional testing, or tests exceeding 10 panels, 150mg of hair is advised. It is beneficial to measure the sample using a jeweler’s scale. In cases where scalp hair isn't available, body hair can be gathered in an equivalent amount. When we mention head hair, we specifically mean scalp hair. Body hair encompasses other types like facial and axillary hair.
Process Overview
The primary stages in laboratory drug test analysis are Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample undergoes initial processing into the laboratory’s database. This step ensures the sample is properly sealed and sent, assigns a random LAN (Laboratory Accessioning Number), and handles any extra data entry not managed through an electronic custody chain system.
Screening features a first rapid assessment for drug abuse presence. Although Screening offers a cost-effective approach to dismiss drug use in most samples, positive outcomes require confirmation for legal validity. Samples with presumptive positives in Screening necessitate follow-up confirmation.
In cases of presumptive positives in the Screening, more hair is extracted from the original sample for the Extraction step. In this phase, drugs are drawn from hair at a more diluted concentration compared to other methods (e.g., urine or oral swabs), making hair drug screening the most challenging technique to execute.
Any screening positive result undergoes confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation, as required. The overall process from Accessioning to Confirmation is conducted with oversight from both the CAP (College of American Pathologists) Hair requirements and the ISO / IEC 17025 standards.
