Accuracy is a key concern when using rapid at-home flu and COVID-19 tests. This article explains how these tests work and their accuracy, helping you trust the results.

How Rapid Tests Work

• Sample Collection: A nasal swab collects a sample from the respiratory tract.
• Antigen Detection: The test identifies viral antigens, indicating the presence of flu or COVID-19.
• Result Display: Results are typically displayed as lines or symbols on the test device.

Factors Affecting Accuracy

• Timing: Testing too early or too late after exposure can affect results.
• Sample Quality: Proper sample collection is crucial for accurate results.
• Test Conditions: Follow the storage and usage instructions for best results.

Comparison with PCR Tests

• Rapid tests are generally less sensitive than PCR tests but provide quicker results.
• They are ideal for initial screening and when immediate results are needed.

Conclusion Understanding the accuracy of rapid at-home tests helps you make informed decisions about your health. Trust the results by following guidelines and using high-quality test kits.
