But some adults and many children under five are unable to get rid of HBV and become chronically infected, which means the symptoms of Hepatitis B may continue throughout their lives. People with HIV are far more likely to develop chronic Hepatitis B infections and progress to cirrhosis quickly. Hepatitis B infection can be diagnosed with a simple blood test. The blood test shows the presence or absence of different types of antigens and antibodies. Antigens are pieces of the virus, which cause the immune system to react and produce antibodies.
Antibodies are part of the bodys defense system against viruses.
If the test is positive for any of the antigens, it means that you are currently infected with the Hepatitis B virus. If you test positive for the antibodies, it means that you have developed immunity against the virus, either after receiving the vaccine or after an active infection has passed. Like HIV, you can avoid getting Hepatitis B by using a condom or other latex barrier while having sex. If you inject drugs, do not share your needles. Also, watch out for items that may have been contaminated with someone else's blood such as toothbrushes, needles and razors used for body piercing, tattooing, acupuncture and shaving.
