CorDx 3-in-1 At-Home Rapid Test Kit — Flu A/B & COVID-19, 4 Tests, Single Nasal Swab, ~10-Min Results

CorDx TyFast is a 3-in-1 at-home rapid antigen test kit that detects SARS-CoV-2, Influenza A, and Influenza B from a single anterior nasal swab and delivers results in about 10 minutes.

When respiratory symptoms appear, identifying the cause quickly helps you make informed decisions about care, isolation, and returning to daily activities. The CorDx TyFast kit combines three antigen tests into one compact package designed for symptomatic use within the first five days after symptoms start. Each box contains materials for four separate tests and clear step-by-step instructions so household members or caregivers can test safely at home without specialized training.

How accurate and fast are CorDx TyFast results?

The TyFast kit is engineered for expedited antigen detection with results typically visible in roughly ten minutes. Its performance, based on manufacturer instructions for use, reports positive percent agreement (PPA) that compares favorably against major competitors. For best accuracy, follow the included instructions and test within the recommended symptom window.

• Result time: approximately 10 minutes per test
• Multiplex design: SARS-CoV-2, Influenza A, and Influenza B from one swab
• Intended use: symptomatic individuals within 5 days of symptom onset
• Includes 4 complete test sets per box for household testing

What comes in the kit and how simple is the sample collection?

Each test set includes a short anterior nasal swab, extraction buffer, test strip, and a clear instruction leaflet. The sample collection is non-invasive: insert the short swab a small distance into each nostril, rotate as instructed, then mix the swab in the buffer before applying drops to the test cassette. The process is designed for at-home convenience without the need for specialized tools.

• Single anterior nasal swab per test—no deep nasal insertion
• Step-by-step instructions included with diagrams
• All reagents and disposable components provided for four tests
• Quick interpretation window—read results around 10 minutes

When should I use the TyFast test and what does a positive or negative result mean?

Use the test if you are experiencing respiratory symptoms and are within five days of symptom onset, as the kit is validated for symptomatic testing. A positive line for any target indicates antigen detection for that specific virus, while a negative result suggests absence of detectable antigens at the time of testing; consider retesting or follow-up with a healthcare provider if symptoms persist or worsen.

• Best used within first 5 days of symptoms
• Positive = antigen detected for SARS-CoV-2, Influenza A, or B
• Negative = no antigen detected; consider repeat testing if symptomatic
• Not intended as a substitute for clinical diagnosis by a healthcare professional

How should I store, dispose of, and interpret safety information for home use?

Store the test kit according to the temperature instructions on the box and keep components sealed until use. Dispose of used swabs and test cassettes in household trash following local rules, and wash hands after handling. If you receive a positive result or severe symptoms develop, seek medical guidance promptly and follow local public-health recommendations for isolation and care.

• Store unopened kits at recommended temperatures on box label
• Use each test immediately after opening components
• Discard used materials in household waste unless local rules differ
• Contact a healthcare provider for confirmatory testing or treatment advice
