COVID-19 Testing

---

COVID-19 testing plays a vital role in detecting the presence of the SARS-CoV-2 virus, the cause of COVID-19. These diagnostic tests are essential for identifying infected individuals, including those who are asymptomatic or presymptomatic, to help prevent further transmission. Several types of COVID-19 tests are available:

• Polymerase Chain Reaction (PCR) Test: Widely regarded as the gold standard for COVID-19 diagnosis, PCR tests detect the virus's genetic material (RNA) in respiratory samples like nasal swabs, throat swabs, or saliva. These tests are highly accurate and reliable for identifying active infections.
• Antigen Test: Antigen tests detect specific proteins on the surface of the virus. These tests are commonly used for quick screening, delivering results in as little as 15-30 minutes. While not as sensitive as PCR tests, antigen tests are valuable in situations requiring rapid results.
• Antibody (Serology) Test: Antibody tests determine if an individual has previously been infected by detecting antibodies in the blood. These tests are not used to diagnose active infections but are useful for understanding past exposure to the virus.

COVID-19 testing is recommended for those with symptoms, close contacts of confirmed cases, or individuals in high-risk settings. Testing protocols vary based on local guidelines, available resources, and community infection rates. Adhering to healthcare professionals' advice on testing and preventive measures is crucial for controlling the spread of COVID-19.
