Our review of the CorDx Tyfast At Home Flu A/B and COVID-19 Multiplex Rapid Test finds it best suited for households, schools, and clinics that need quick, on-the-spot antigen screening.

Key Features

• Rapid results: Provides a readable result in about 10 minutes so decisions can be made quickly without a laboratory wait.
• Multiplex detection: Detects influenza A and B antigens plus SARS-CoV-2 nucleocapsid protein antigens in a single assay, reducing the need for separate tests.
• At-home convenience: Designed for use outside clinical settings so users can test privately and avoid a visit to a provider for initial screening.
• FDA EUA authorized: Authorized for use in the United States, offering regulatory credibility for home and institutional use.
• Versatile settings: Suitable for homes, schools, care facilities, clinics, and hospitals where rapid screening is useful.

Who It's For

The kit is a practical option for families who want a simple, reliable way to screen symptomatic members or to monitor exposure over a season, and for small organizations that need a cost-effective testing supply. Its 25-test format suits repeat testing schedules and group settings where multiple people may need screening.

It is not intended as a replacement for diagnostic PCR when definitive clinical decisions require laboratory-grade sensitivity; those who need confirmatory testing or official documentation for travel or formal medical decisions should seek laboratory testing instead.
