Hair analysis is recognized as a robust method for identifying drug and alcohol consumption. Offering a long-term history, hair captures biomarkers within the fibers of the growing hair strand. When collected near the scalp, it can present a detection span for alcohol and drugs of roughly 3 months. Hair is easy to gather, difficult to tamper with, and straightforward to ship.
A 1.5-inch segment of around 200 hair strands (similar to a #2 pencil in size) closest to the scalp yields 100mg, which is ideal for both screening and confirmation. An additional 150mg of the sample is advised for EtG, add-ons, and/or tests exceeding 10 panels. We advise the use of a jeweler’s scale to weigh the specimen. If scalp hair isn’t available, a similar quantity of body hair can be collected. By head hair, we mean scalp hair exclusively, while body hair refers to other types such as facial and axillary hair.
Process Overview
The principal stages in processing a drug test in the lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial processing of a sample into the lab’s system. This step includes ensuring the sample was sealed and shipped properly, allocating a random LAN (Laboratory Accessioning Number), and completing any necessary data entry not covered by an electronic chain of custody system.
Screening performs an initial rapid test for drugs. While it serves as an economical method to rule out drug use in numerous samples, a positive screening requires confirmation for legal admissibility. Any samples preliminarily positive in Screening need secondary confirmation.
If a sample shows a presumptive positive in Screening, additional hair is retrieved from the initial specimen for Extraction. Here, drugs are extracted from hair at a much lower concentration compared to other methods like urine or oral fluid, making hair drug testing the most challenging to execute.
Confirmed positive screening results are obtained through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples are washed prior to confirmation as necessary. The complete laboratory process from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
