Seen as a strong method for detecting drug and alcohol consumption, hair testing captures a long-term history of substances by embedding biomarkers within the fibers of growing hair. Collected near the scalp, hair offers up to a 3-month detection window for alcohol and drugs. It's easy to gather, hard to tamper with, and straightforward to transport.
A sample measuring 1.5 inches with around 200 hair strands (about #2 pencil size) closest to the scalp yields 100mg, ideal for screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, 150mg of hair is suggested. We advise using a jeweler's scale to weigh the sample. If scalp hair is not feasible, a similar amount of body hair can be used. When we talk about head hair, we mean scalp hair specifically. Body hair encompasses all other forms (facial, axillary, etc.).
Process Overview
The laboratory drug test processing involves four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step, integrating a sample into the lab's system. It verifies the sample's proper sealing and shipment, assigns a random LAN (Laboratory Accessioning Number), and completes any missing data entry not included in an electronic chain of custody system.
Screening conducts an initial rapid check for drug misuse. While a cost-effective approach to negate drug use in most samples, a positive screen requires confirmation for court acceptance. Any presumptive positive samples in Screening need secondary confirmation.
If Screening suggests a positive result, more hair is extracted from the initial specimen for further Extraction. Drugs are then extracted from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), which makes hair drug screening particularly challenging.
Confirmation of positive screening uses GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo washing before confirmation if necessary. From Accessioning to Confirmation, the complete lab process is reviewed under CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.
