The utilization of hair testing is recognized as a potent method for identifying drug and alcohol consumption. Hair captures a long-term record by embedding biomarkers within the fibers as it grows. When taken near the scalp, it offers a detection window of up to three months for both alcohol and various substances. Collection of hair is straightforward, tampering is challenging, and transportation is uncomplicated.
A sample measuring 1.5 inches containing roughly 200 hair strands—comparable to the girth of a #2 pencil—yields 100mg of hair, which is optimal for screening and verification. For EtG assessments, add-ons, or tests exceeding 10 panels, a 150mg specimen is advisable. We suggest using a jeweler’s scale for precision. If scalp hair is not present, a similar amount of body hair is usable. The term head hair specifically pertains to scalp hair, whereas body hair covers all other types (facial, axillary, etc.).
Process Overview
The fundamental phases in the lab processing of drug test outcomes include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary handling of a sample within a lab's framework. It involves ensuring the integrity and proper shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and finalizing any necessary data input not incorporated by an electronic chain of custody system.
Screening offers a swift evaluation for drugs of misuse. Although Screening economically eliminates drug presence in most specimens, a positive result necessitates confirmation for court relevance. Presumptively positive cases in Screening demand subsequent verification.
When a sample exhibits a presumptive positive status during the Screening phase, additional hair is extracted from the initial sample for the Extraction phase. During Extraction, drugs are isolated from hair at much lower concentrations compared to other methods (such as urine or oral fluid), presenting hair drug testing as the most arduous method to execute.
Verification of any positive screening outcome is undertaken using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo a wash before confirmation if needed. The comprehensive lab procedure from Accessioning to Confirmation is scrutinized under CAP (College of American Pathologists) Hair criteria and conforms to ISO / IEC 17025 standards.
