Rapid COVID19 Test Kits Face Network Congestion Challenges

As COVID-19 antigen testing becomes a routine part of pandemic management, many users of SARS-CoV-2 rapid antigen test kits (colloidal gold method) have encountered submission failures with "network congestion" error messages. This article examines the potential causes behind these technical difficulties and provides practical solutions.

1. High User Volume: When numerous users simultaneously attempt to submit data through the same network, servers may become overloaded—similar to traffic congestion during rush hour.

2. Security Protocol Activation: Web security systems sometimes misinterpret high-frequency requests from a single network as potential Distributed Denial-of-Service (DDoS) attacks, triggering protective measures that temporarily restrict access.

1. Delayed Resubmission: If encountering network congestion alerts, waiting several minutes before retrying—particularly outside peak hours—often resolves the issue by reducing server load.

2. Technical Support Contact: Persistent problems warrant contacting the platform's administrators, who can investigate specific issues and potentially suggest alternative submission methods or network configurations.

• Network Stability: Verify your internet connection remains consistent throughout the submission process.
• Browser Maintenance: Clearing cached data and updating to the latest browser version can resolve compatibility issues.
• Instruction Compliance: Carefully follow test kit guidelines, particularly regarding file format requirements for any image or video uploads.

Understanding these technical challenges and implementing appropriate solutions ensures more efficient use of antigen testing resources, contributing to effective public health monitoring during ongoing pandemic conditions.
