Hair testing is recognized as an effective method for identifying alcohol and drug use. Hair can reveal a comprehensive history of substance use by capturing biomarkers within the fibers of the growing hair strand. When samples are taken near the scalp, hair can show drug and alcohol presence over roughly a 3-month period. It is straightforward to collect, challenging to tamper with, and convenient for shipping.
Collecting a 1.5-inch sample of approximately 200 hair strands, equivalent to the thickness of a #2 pencil, close to the scalp yields 100mg of hair, which is the optimal quantity for analysis. For tests like EtG, add-ons, or those exceeding 10 panels, it's suggested to collect 150mg of the sample. We advise using a jeweler's scale to measure the specimen. In the absence of scalp hair, a similar amount of body hair can be obtained. References to head hair pertain solely to scalp hair, while body hair encompasses other variations (facial, axillary, etc.).
Process Overview
The drug test result process in laboratories includes the key steps of Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of integrating a sample into a laboratory’s system. This step entails verifying the proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing additional entries not covered by an electronic chain of custody.
Screening involves a preliminary assessment for drug presence. While it provides a cost-efficient method to exclude drug use in most samples, a screen yielding a positive outcome must be confirmed for legal acceptance. All samples presumed positive in Screening require a second confirmation.
When a sample tests positive at the Screening phase, extra hair is taken from the original sample and prepared for Extraction. In this phase, substances are isolated from hair at lower concentrations compared to other methods (like urine or saliva), making hair drug testing the most challenging method to conduct.
Confirmations for any positive screenings are carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are washed as necessary. The complete lab process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair criteria and in accordance with ISO / IEC 17025 standards.
