The SARS-CoV-2 Antigen Test detects active COVID-19 infections.
Purpose: It detects specific proteins, or antigens, associated with the SARS-CoV-2 virus, typically found on the virus surface.
Detection: When the virus is present in the respiratory tract, these proteins can be detected early in infection when viral loads are high.
Time for Results: Antigen tests provide results within 15-30 minutes, which is much faster than PCR tests, though typically less sensitive.
1] Sample Collection : The test requires a swab sample, often taken from the nasal cavity or throat.
2] Testing Procedure : The sample is treated with reagents that break open the virus and allow the antigens to interact with test-specific antibodies on the testing device.
3] Result Interpretation : The device displays a visual marker (similar to a pregnancy test) to show if antigens were detected.
1] Rapid Screening in High-Traffic Areas: Ideal for quick screening in airports, schools, offices, and hospitals.
2] Outbreak Control: Enables fast identification and isolation of cases in outbreak situations, helping to control virus spread.
3] Testing in Symptomatic and Asymptomatic Individuals: Primarily recommended for symptomatic individuals but can be used in asymptomatic individuals where rapid results are necessary.
1] Speed: Offers near-immediate results.
2] Cost-Effective: Typically less expensive than molecular tests like PCR.
3] Convenience: Easy to administer and doesn't always require specialized laboratory equipment.
1] Sensitivity: Antigen tests are generally less sensitive than PCR tests, meaning they may produce false negatives, especially in cases with low viral loads.
2] Best for Early Stages: Most accurate when administered during the first few days of infection when viral load is highest.
1] Positive Result: Indicates an active infection. Immediate isolation and follow-up with healthcare providers are recommended.
2] Negative Result: Suggests no detectable antigen at the time, though false negatives can occur, particularly if the viral load is low.
3] Indeterminate/Invalid Result: Indicates a test error or incomplete sample and requires retesting.

PCR tests detect viral RNA, which is highly sensitive and detects even small amounts of virus, while antigen tests detect viral proteins and are quicker but less sensitive.
It depends on the travel regulations; many countries prefer PCR tests for entry due to their higher sensitivity.
They are less accurate for asymptomatic cases, but may still be used for initial screening in certain contexts.
Follow isolation guidelines, inform close contacts, and consult with healthcare providers for further steps.
People showing COVID-19 symptoms, those exposed to confirmed cases, or individuals needing quick testing for entry into certain public spaces.
