Hair testing is now recognized as an effective method for detecting drug and alcohol use. It offers a comprehensive history of drug consumption by capturing biomarkers within the fibers of the hair as it grows. When hair is collected near the scalp, it can reveal drug and alcohol use over a period of up to three months. Hair collection is straightforward, hard to tamper with, and easy to transport.
A sample measuring 1.5 inches, roughly comprising 200 strands of hair (around the thickness of a #2 pencil) from the scalp, equates to 100mg, which is the optimal amount for initial testing and validation. For EtG tests, add-ons, and/or assays exceeding 10 panels, a 150mg sample is advised. It is best to use a jeweler's scale to measure the sample weight. If scalp hair isn't available, a comparable amount of body hair can be collected. "Head hair" pertains solely to scalp hair. "Body hair" includes facial, axillary, and other types of hair.
Process Overview
The laboratory procedure for processing a drug test result consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning initiates with incorporating a sample into the lab's system. This step includes verifying the proper sealing and shipment of the sample, assigning a LAN (Laboratory Accessioning Number), and completing any outstanding data entry not provided by an electronic chain of custody system.
Screening conducts an initial examination for drug substances. While cost-effective for excluding drug usage in most cases, a positive screening result must be confirmed to be legally defensible. Samples with a presumptive positive in Screening necessitate further confirmation.
If a specimen yields a presumptive positive in Screening, an additional portion of hair from the original sample is prepared for Extraction. This phase extracts drug substances from hair at a much lower concentration than other methods (e.g., urine or oral fluid)—this is why hair drug screening is the most challenging technique.
Confirmation of a positive Screening result is done using GC/MS, GC/MS/MS, or LC/MS/MS technology. Presumptive positive samples are washed before confirmation if needed. The complete laboratory process, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair standards and accredited to ISO / IEC 17025 criteria.
Advantages of hair drug testing:
Limitations:
Note: Although commonly called "hair follicle tests", the test examines the hair strand rather than the follicle beneath the scalp.
In Two Rivers, WI, hair follicle testing surpasses urine testing in various ways. The superior accuracy and reliability of hair tests demonstrate their advantage.
