Self Test Covid-19 What it is: a rapid self-administered antigen test that detects the presence of the SARS-CoV-2 virus antigen, an indicator of active infection.|| When to use it: ideal in cases of suspected exposure, in the presence of symptoms (fever, cough, sore throat, loss of taste/smell) or for routine periodic screening.|| How it works:| Rinse/disinfect your hands and prepare the materials.|| Collect a regulatory sample (e.g., nasal swab or nasopharyngeal swab depending on the package).|| Insert the swab into the extractor, transfer it to the test cassette.|| Wait for the tempo indicated (usually 15 minutes) and read the result.|| | Interpretation of the result:| Two lines (control + test) → positive result: antigen detected → it is very likely that there is an active infection.|| Una single control line → negative result: antigen not detected (but does not completely rule out infection).|| No control line → invalid test → repeat with a new kit.|| | Advantages: quick, easy to use at home, useful for quickly deciding on isolation or further testing.|| Limitations:| A negative result does not guarantee the absence of infection (especially in the early stages or with low viral load).|| A positive result requires confirmation according to clinical guidelines and does not replace a molecular test (PCR).|| | Precautions: carefully follow the instructions do not use after expiration store the kit according to instructions in case of severe symptoms or clinical worsening contact a doctor regardless of the test result.
