Rapid Antigen Test

A rapid antigen test detects specific viral or bacterial proteins in a sample, most commonly from a nasal or throat swab, providing results within minutes rather than the hours or days needed for laboratory-based testing. It is widely used for the quick diagnosis of infections such as COVID-19, influenza and streptococcal throat infection, allowing immediate clinical decisions about isolation, treatment or further testing. While convenient and fast, rapid antigen tests are generally less sensitive than PCR testing, meaning a negative result in a symptomatic patient may need confirmation with a more sensitive test. The test's speed makes it especially valuable in point-of-care settings such as clinics, emergency rooms and community screening programs.

Rapid Antigen Test is recommended for patients diagnosed with specific conditions where other approaches have been insufficient. Your Infectious Diseases specialist will assess your suitability based on your diagnosis, health history, and treatment goals.

The typical duration is 15-30 minutes. This may vary based on the complexity of your case and individual response to treatment.

Recovery typically takes No recovery time is needed as the test involves only a brief swab collection. Patients can resume normal activities immediately after the sample is taken. Based on the result, the physician advises on isolation, treatment or further confirmatory testing as appropriate.. Your care team will provide specific instructions based on your response and overall health.

Side effects vary by individual and are detailed in the section above. Your specialist will discuss all risks and benefits with you before treatment begins. Serious adverse effects are uncommon but are part of the informed consent process.

Rapid Antigen Test has a documented success rate of 70-85% sensitivity at accredited facilities. Outcomes depend on disease stage, patient health, and adherence to the treatment plan and aftercare instructions.
