The Flowflex COVID‑19 Antigen Home Test (1‑test kit) is a compact and accessible at‑home diagnostic tool that uses a simple anterior nasal swab to detect SARS‑CoV‑2 antigens with rapid results—typically within 15 minutes. Authorized for over-the-counter (OTC) use under FDA Emergency Use Authorization (EUA), it offers a user-friendly experience suitable for individuals aged 2 years and up (via adult administration), including those with and without symptoms. The kit includes a test cassette, extraction buffer tube, disposable nasal swab, and instructions for use. Clinical evaluation has demonstrated robust performance, with positive percent agreement (sensitivity) around 93% and negative percent agreement (specificity) at 100% compared to RT-PCR benchmarks. Flowflex is CE-marked, and evaluations in Europe report even higher accuracy—up to 97.1% sensitivity, 99.5% specificity, and 98.8% overall accuracy—with a generous 24-month shelf life stored at room temperature. Affordable, portable, and straightforward to use, Flowflex provides fast, reliable insights into COVID‑19 status in the comfort of home—making it a convenient choice for individuals, families, or on‑the‑go testing needs.
