Anti Hbs (Mikropartikül Immün Assay-Meia Veya Benzeri)
Anti HBs is an antibody produced by the body against the protein surface antigen of the Hepatitis B virus. So, what is anti-HB elevation? All curious questions, such as anti-HBs negativity and HBs value, are in our article.

What are Anti HBs?
Hepatitis B virus is a DNA virus belonging to the Hepadnaviridae family. Hepatitis B virus contains various proteins with antigenic properties. One of these is the S protein, located on the virus’s surface and originates from the first letter of the English word ‘surface.’ The way to understand whether antibodies have formed in the body against this protein structure is to look at the Anti HBs value in the blood.
Anti HBS is an antibody produced by the body against the surface antigens of the hepatitis B virus. Hepatitis B virus, which manifests itself in mild and severe symptoms, can be transmitted from person to person through blood and fluid.
Hepatitis-B disease can occur acutely and chronically, and while hepatitis-B cases do not show symptoms for a long time, if left untreated, they can cause serious problems, especially in the liver. Whether the body is immune to the hepatitis-B virus is determined by the anti-HBS test.
What Does Anti HBs Positive Mean? (Anti RLS Height)
Anti-HB positive (anti-HBS high) indicates that the person remains generally protected against Hepatitis B virus infection, including its value in the blood. Hepatitis B virus causes symptomatic/asymptomatic acute viral hepatitis B virus infection after entering the body. Suppose a positive Anti HBs test remains detected in the blood of a person who develops acute viral hepatitis B virus infection within 6 months at the latest. In that case, this indicates that the disease has remained cured. 
In other words, if a person exposed to Hepatitis B virus infection remains detected as positive for Anti HBs in the blood after a while (within six months at the latest), this situation shows that you have recovered from hepatitis B virus infection and remain protected against it, you will not get the disease again, and you are no longer contagious.
Anti-positivity can also remain achieved without contracting the disease. This remains achieved by completing the doses within the framework of the vaccination scheme with existing vaccines against the Hepatitis B virus. The vaccine aims to ensure the formation of antibodies (Anti-HBs) against the S protein of the Hepatitis B virus. However, for this to happen, it must first remain shown that the person has not encountered the Hepatitis B virus.
What Should be the Normal Anti HBs Value?
“What should be the anti-HBs value?” The answer remains: An Anti-HBs value of ≥10 mIU/mL in the blood, both after experiencing the disease and after the vaccination program, indicates antibodies’ formation at a protective level. The value shouldn’t be below this level, <10 mIU/ml.
It should remain in mind that in a person whose anti-HBs value remains detected at ten mIU/ml and above (10 – 100 mIU/ml), it may decrease to <10 mIU/ml over the years. In such cases, a dose reminder for Hepatitis B vaccine administration may be necessary.
“What does Anti HBs 1000 mean?” The answer remains as follows: When discussing the protectiveness of the anti-HBs value, there is no difference between the value being at any value above ≥10 mIU/mL and this value reaching 1000 mIU/mL. This indicates the amount of antibodies formed against the virus entering the body. However, an Anti-HBs value of ≥10 mIU/mL suggests adequate protection.
Hepatitis B Virus Infection
The infectious disease caused by the Hepatitis B virus is common worldwide. Transmission of the virus is often from an infected mother to the baby during birth, as a result of sexual intercourse with an infected person, as a result of contact with blood and body fluids containing the virus, and damaged skin and mucosa.
Or as a result of shared use and intravenous application of a needle containing infected blood and body fluid, as in drug addicts. Apart from this, using infected medical instruments or shared tools and equipment without sterilization also leads to the transmission of the Hepatitis B virus.
After the virus enters the body, the target organ is the liver. Once there, it causes acute and chronic infectious diseases. It remains estimated that nearly 300 million people in the world live with chronic Hepatitis B virus infection, and an average of 1.5 million people remain infected with Hepatitis B virus every year. Unmonitored chronic Hepatitis B virus infections result in the development of cirrhosis and liver cancer over time.
How Much Should Anti-HBS Be?
The answer to how much anti-HBS should remain required varies between individuals, whether they are immune to the hepatitis B virus. While people who have remained vaccinated and have the disease experience anti-HBS positive results, people who get anti-HBS adverse effects are vulnerable to the disease.
In adults vaccinated and with the disease, the anti-HBS value remains expected to be over 10 ml. These people remain protected from the condition for a long time, but there is no harm in having a reminder dose in the future.
The anti-HBS value can sometimes exceed 10 ml, even in people without immunity. The specialist doctor will give the most accurate answer when faced with such results.
What is Anti RLS Positive?
A high anti-HBS value, a positive anti-HBS in the blood test, indicates that the person is immune and protected against the hepatitis B virus. A 10 mIU/mL test result and above means that the body has created antibodies at a protective level against hepatitis B. A positive anti-RLS test may result from a previous vaccination or contracting and recovering from this infection.
What is Anti-RLS Negative?
While anti-HBS negative indicates that the person does not produce antibodies against hepatitis B disease and remains unprotected. It also means that he has not remained vaccinated or had the disease before. To remains protected from the disease, a person must get vaccinated.
However, in some scenarios, the anti-HBS result may be harmful to those who are immune. The main reason for this may be that the virus is still in the incubation period.
