Hair analysis has become known as an effective method for identifying drug and alcohol consumption. Hair captures biomarkers in the strands as they grow, offering a long-term record of substances like alcohol. If collected from near the scalp, it can reveal substance use within roughly the last 90 days. The collection process is straightforward, making tampering quite challenging, and the samples are easy to send to labs.
For optimal testing, a sample size of 1.5 inches, about 200 hairs (similar in size to a #2 pencil), close to the scalp should weigh around 100mg. This is the perfect amount for screening and verification. For tests requiring EtG, add-ons, or over 10 panels, a 150mg sample size is suggested. We advise weighing the hair on a jeweler’s scale. If scalp hair is not available, a comparable amount of body hair is acceptable. References to head hair specifically mean scalp hair, while body hair includes all other types (such as facial or axillary hair).
Process Overview
The principal stages in processing drug test results in a laboratory include Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the entry of a sample into the lab’s system. It involves ensuring the sample was correctly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and executing additional data inputs not available via an electronic chain of custody form.
Screening is an initial, economical test to identify drug misuse. Although Screening helps rule out drug use for most samples, results must be confirmed for legal admissibility. Presumed positive screenings necessitate a follow-up confirmation.
If Screening yields a presumptive positive, further hair is extracted from the initial sample for the Extraction phase. Here, drugs are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or saliva), making hair drug screening the most complex methodology.
Positive Screening outcomes undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Before confirmation, all presumptively positive results are washed if necessary. The comprehensive lab process, from Accessioning through Confirmation, adheres to CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation standards.
