Abstract

Abstract Overview

Investigation into the impact of radiofrequency interference (RFI) on the accuracy of medical equipment in clinical laboratories.

Objectives

• Explore the potential consequences of RFI on medical devices, specifically looking into its role in producing inaccurate laboratory results.

Methods

A case study involving an unexpected failure of a hematology analyzer, which triggered the investigation. The association between malfunctioning equipment and RFI from a nearby enhanced antenna was scrutinized.

Results

An increase in power output from an antenna, located near the analyzer, was identified to impact the device's function, leading to abnormal white blood cell (WBC) counts. Temporarily shutting down the antenna reversed the anomalies, confirming RFI as the cause.

Conclusion

The findings affirm that RFI can distort laboratory outcomes and must be considered a significant risk factor in clinical settings. Proactive measures against RFI are recommended to safeguard the accuracy of laboratory results.
