Buying Guide
What should I look for in an RSV/Flu/COVID home test kit?
- Number of targets: Decide if you need RSV alone or a 4‑in‑1 panel for RSV, Flu A, Flu B, and COVID-19.

- Turnaround time: Most rapid tests provide results in about 15 minutes; confirm the exact window in the product instructions.
- Testing frequency: Consider kits with multiple tests if you expect repeated exposure or household use.
- Quality and approvals: Look for FDA or CLIA waivers when applicable and manufacturer notes on clinical evaluation standards.
