Hair analysis is now viewed as an effective method for identifying the usage of drugs and alcohol. Hair acts as a record of past substance use by embedding biomarkers within the fibers of the hair as it grows. When cut near the scalp, hair captures up to a three-month timeframe for detecting alcohol and other substances. It is straightforward to gather, less likely to be tampered with, and simple to transport.
A hair sample from 200 strands, measuring 1.5 inches near the scalp, will produce 100mg, which is ideal for both screening and validation. For EtG, additional tests, or tests above 10 panels, a specimen of 150mg is suggested. It's best to weigh the specimen using a jeweler’s scale. If scalp hair is not an option, a similar amount of body hair should be collected. References to head hair solely imply scalp hair, whereas body hair includes all other hair types like facial, axillary, etc.
Process Overview
The laboratory processing of a drug test encompasses four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning handles the initial integration of a specimen into a lab’s system. This step ensures the sample is properly sealed and shipped, assigns a Laboratory Accessioning Number (LAN), and completes any lacking information not included by an electronic custody system.
Screening provides an initial, rapid assessment for drug abuse. While cost-effective for ruling out drugs in most samples, a positive screening result must be confirmed to be legally accepted. Any samples with presumptive positive results during Screening must undergo secondary confirmation.
For samples with presumptive positivity at the Screening phase, extra hair is extracted from the initial sample for Extraction. In this phase, substances are extracted from hair at far lower levels than other methods (e.g., urine or oral fluid), hence making hair drug screenings the most intricate to perform.
Confirmation of any positive result is achieved through techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleaned before confirmation as necessary. The entire lab procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair criterion and adherence to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Though often termed "hair follicle tests", the analysis targets the hair strand rather than the follicle beneath the scalp.
