Hepatitis B:

Hepatitis B is a viral infection that affects the liver and can lead to chronic liver disease, including cirrhosis and liver cancer. Testing for hepatitis B is essential to diagnose the infection, assess the stage of the disease, and determine the need for treatment or monitoring. It helps identify individuals who are carriers of the virus, evaluate liver function, and guide preventive measures such as vaccination for at-risk individuals. Testing is crucial for early intervention, preventing transmission, and managing the long-term consequences of hepatitis B infection.
