Hepatitis B Surface Antigen; Quantitative (Cmia)

According to WHO, Hepatitis is an inflammation of the liver that is caused by a variety of infectious viruses and non-infectious agents leading to a range of health problems, some of which can be fatal. There are five main strains of the Hepatitis virus, referred to as type A, B, C, D and E.

All of these viruses cause liver infection, they differ in their mode of transmission, severity and geographical distribution. Types B and C lead to chronic disease in hundreds of millions of people and together are the most common cause of liver cirrhosis, liver cancer and viral hepatitis-related deaths. It is a major global health problem. It can cause chronic infection and puts people at high risk of death from cirrhosis and liver cancer.

The virus is most commonly transmitted from mother to child during birth and delivery, as well as through contact with blood or other body fluids during sex with an infected partner, unsafe injections or exposure to sharp instruments. Hepatitis B can be prevented by vaccines that are safe, available and effective.

HBsAg is the most important serum marker for diagnosing HBV infection.

Why HBsAg test in Aluva?

Hepatitis type B and C lead to chronic disease in hundreds of millions of people and together are the most common cause of liver cirrhosis, liver cancer and viral hepatitis-related deaths. It is not possible on clinical grounds to differentiate Hepatitis B from Hepatitis caused by other viral agents, hence laboratory confirmation of the diagnosis is essential.

Your doctor will ask you to do this test if, you have symptoms of liver damage:

• Jaundice, a condition that causes your skin and eyes to turn yellow

2. Sexual activity with someone who has been infected with Hepatitis B

3. Living in close contact with a Hepatitis B infected person
