Hair testing is recognized as an effective method for detecting substance use. Hair captures a prolonged record of drug and alcohol consumption by embedding biomarkers within its growing fibers. When collected near the scalp, hair offers an approximate 3-month detection window for these substances. The collection process is straightforward, and the samples are resistant to tampering and easy to transport.
A sample measuring 1.5 inches of about 200 hair strands (comparable to a #2 pencil) from the scalp yields 100mg, which is the preferred amount for analysis and verification. For EtG, additional tests, or when exceeding 10-panel tests, 150mg is advised. It is advisable to weigh the sample using a jeweler’s scale. If scalp hair is not accessible, a similar quantity of body hair may be gathered. When we mention head hair, we expressly mean scalp hair. Body hair includes any other types (such as facial or axillary hair).
Process Overview
The laboratory processing of a drug test result involves four main stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step that integrates the sample into the laboratory’s system. This step ensures that the sample is sealed and delivered correctly, assigns it a unique LAN (Laboratory Accessioning Number), and completes any additional data entry not captured electronically by the chain of custody system.
Screening provides an initial evaluation for the presence of drugs. Though cost-effective for ruling out usage in most samples, a positive result in Screening needs validation to be legally admissible. Samples with a presumptive positive result in Screening require further confirmation.
Upon receiving a presumptive positive in the Screening phase, additional hair is processed for Extraction. During Extraction, drugs are isolated from hair at lower concentrations compared to other methods (e.g., urine or saliva), making hair testing the most challenging methodology.
Any positive findings from Screening must be affirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo a cleaning process before Confirmation if necessary. Every stage from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 standards.
