Sejoy SARS-CoV-2 antigen rapid test: what to know

The kit is designed for a nasal or other specified respiratory sample, depending on its instructions. A positive result supports current COVID-19 infection, but a clinician may interpret it alongside symptoms, exposure and timing. A negative result means the test did not detect enough target material in that sample; it does not rule out infection when symptoms or exposure remain concerning. COVID-19 and COVID-19 Test information can help explain the wider diagnostic context. The Rapid Antigen Test Kit page describes the technology category.

Check the package, expiry information and instructions before starting. Wash or sanitise hands, collect the sample exactly as directed, add it to the test device, and read the result only within the stated reading window. Do not interpret a dried test outside that window. Keep the test level and dispose of used materials as instructed. If positive, follow local clinical advice and reduce close contact while arranging guidance. If negative but symptoms continue, ask a clinician whether repeat or laboratory testing is appropriate.

The test result does not measure illness severity. Seek emergency care for difficulty breathing, chest pressure, blue or grey lips, new confusion, inability to stay awake, or rapidly worsening illness. Contact a clinician promptly if you are pregnant, immunocompromised, have significant long-term conditions, or symptoms are worsening despite a negative test.

Ask whether the result fits your symptoms and timing, whether another test is needed, how long to limit close contact, and which treatments or monitoring apply to your situation.
