COVID-19 Positive Test Result

Multiple items are arranged on a surface covered with printed instructions. A test cassette displays two pink lines next to letters "C" and "T" along with "SARS-CoV-2 Ag" printed on it, indicating a COVID-19 self-test. Next to it, a torn foil packet reads "SARS-CoV-2 Antigen Rapid Test (Self Testing)" with manufacturer details: "ACON Biotech (Hangzhou) Co., Ltd" and other symbols. A plastic bag contains a biohazard symbol—a black circle with three circular shapes inside, encircled by yellow. An unopened pad or wipe packet is partially visible. The background features diagrams and text, possibly in a Slavic language, providing instructions for the test.
