Hair tests are recognized as an effective resource for identifying alcohol and drug usage. Hair offers a prolonged timeline of substance history by capturing biomarkers within the growing hair fibers. When gathered near the scalp, hair provides roughly a 3-month timeframe for detecting alcohol and drugs. It's easy to collect, hard to tamper with, and simple to transport.
A 1.5-inch section of roughly 200 hair strands (about a #2 pencil's width) closest to the scalp yields 100mg, which is the perfect amount for both screening and verification. For EtG, add-ons, and tests over 10 panels, 150mg is advised. We suggest weighing the sample on a jeweler's scale. If scalp hair isn't available, an equivalent amount of body hair can be collected. "Head hair" refers specifically to scalp hair, while "body hair" indicates all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result includes four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the process of formally entering a sample into the lab's system. This step involves confirming the sample was sealed and sent correctly, assigning a random LAN (Laboratory Accessioning Number), and filling out any extra data not included via an electronic chain of custody system.
Screening entails an initial rapid assessment for drugs of abuse. Screening is a cost-efficient method for excluding drug usage in most samples, but a positive screen needs verification to be court-admissible. Samples that are presumptively positive require further confirmation.
If a sample indicates positive during Screening, additional hair is extracted from the initial collection and prepared for Extraction. In this stage, the extraction of drugs from hair occurs at much lower concentrations than other methods (e.g., urine, oral fluid), making hair drug screening notably challenging.
Confirmation of any presumptive positive result is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if necessary. The end-to-end process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair guidelines and accredited to ISO / IEC 17025 standards.
