What Does Anti HBS Positive Mean?
When the anti-HBS result is obtained by laboratory test, a negative value means that there is no immunity against Hepatitis B virus in the body. The frequently asked question is “What does anti-HBS negative mean?”, can be answered in this way. It is quite normal for people who have not had hepatitis B vaccine to have anti-HBS. However, the fact that the negative Anti-HBS result does not mean that the person is not suffering from hepatitis B and is not affected by infection. In order to understand this condition, the level of HBsAg known as Hepatitis B surface antigen test should be checked. The negative value obtained by the anti-HBS level at 5.0 mIU/ml indicates that the body does not produce antibodies against the antigen identified as HBsAG on the surface of the Hepatitis B virus in the presence of Hepatitis B due to acute or chronic hepatitis. It is recommended that the person be vaccinated in case of anti-HBS negative value, which is an indication that the person has not been exposed to hepatitis B virus or had not been vaccinated before. Hepatitis B, which has a worldwide prevalence of 5%, can lead to fatal diseases such as liver cancer, and the patient is reminded that he can easily gain protection through vaccination.

What Is Hepatitis B Surface Antibody?
When you are exposed to HBV, your body mounts an immune defense to specifically target and neutralize the invader. Unlike innate immunity which mounts a generalized defense against all invaders, this type of immunity (called acquired immunity) is disease-specific.
What does it mean when HBsAb is positive?

What is HBsAg?
Hepatitis B surface antigen (HBsAg) is a protein on the surface of hepatitis B virus. Hepatitis B surface antibodies are produced by the body’s immune system in response to HBsAg. The presence of adequate hepatitis B surface antibodies in the blood indicates protection against hepatitis B virus infection.

How to detect HBsAg?
The HBsAg can be detected by a simple blood test and a positive test result indicates a person is infected with the hepatitis B virus. The inner core of the virus is a protein shell referred to as the hepatitis B core antigen or "HBcAg," which contains the hepatitis B virus DNA and enzymes used in viral replication.
How many people have hepatitis B?

What is the function of hepatitis?
Makes clotting factors to stop excessive bleeding after cuts or injuries. Produces immune factors and removes bacteria from the bloodstream to combat infection. Releases a substance called "bile" to help digest food and absorb important nutrients. The word “hepatitis” actually means “inflammation” of the liver.
Where does the virus enter the cell?
The virus enters the host liver cell and is transported into the nucleus of the liver cell. Once inside the nucleus, the viral DNA is transformed into a covalently closed circular DNA (cccDNA), which serves as a template for viral replication (creation of new hepatitis B virus).
Overview
Prevention
- Most people infected with hepatitis B as adults recover fully, even if their signs and symptoms are severe. Infants and children are more likely to develop a chronic hepatitis B infection. A vaccine can prevent hepatitis B, but there's no cure if you have it. If you're infected, taking certain precautions can help prevent spreading HBV to others.
Symptoms
- Signs and symptoms of hepatitis B, ranging from mild to severe, usually appear about one to four months after you've been infected. They may include:
Causes
- If you are positive for HBsAg, your blood and body fluids contain the virus and you can transmit it to others. Your body can produce antibodies to any of these antigens once you are exposed to the virus. These antibodies develop at different stages of the infection.
Diagnosis
- HBsAg is cleared within four to six months in self-limited infections (infections that resolve by themselves). It can be detected in the blood during both acute infections (infections that come on suddenly) and chronic infections (infections that last for longer than six months). In addition to the signs and symptoms that a patient has, additional antibodies can be tested to distinguish betwe…
Pathophysiology
- At the center of the hepatitis B virus is DNA, which contains the genes the virus uses to replicate itself. Surrounding the DNA is a protein called hepatitis B core antigen (HBcAG), which cannot be detected with blood tests. Surrounding this is HBsAg, which is actually part of the \"envelope\" that protects the virus from attack by the body's immune system. However, the immune system is go…
