How Do You Get Hepatitis C
Hepatitis C is a blood-borne illness, meaning it is transmitted via contact with infected blood. Usually the virus enters the body through a puncture wound on the skin. The most common way hepatitis C is transmitted is via injection drug use. Sharing dirty needles with someone who is infected can transmit hepatitis C. Health care professionals may contract the virus via needlestick injury. Prior to 1992, the U.S. blood supply was not screened the way it is today, so some people contracted hepatitis C from infected blood transfusions. Rarely, babies born to hepatitis C-infected mothers acquire the virus. Hepatitis C can also be spread by having sex with an infected person or sharing personal items with someone who has the virus, but these cases are rare.
What Is Hepatitis B Surface Antibody
When you are exposed to hepatitis B, your body mounts an immune reaction against it as an invader. This happens whether you are exposed due to blood or sexual contact or if you are vaccinated with the hepatitis B vaccine.
The hepatitis B virus has proteins on its surface that cause your immune system to produce antibodies. With the vaccine, the sample contains the protein only and not the virus itself.
The first response your body will make when exposed to hepatitis B is to manufacture hepatitis B IgM antibodies. These early antibodies are produced to fight against several parts of the virus including its core. These antibodies are seen in the initial response, but they eventually fade away.
Your immune system then begins to produce IgG antibodies. It continues to produce these antibodies for the rest of your life. In this way, your immune system is always ready to attack hepatitis B virus when it is exposed to it.

How Is The Hbcab Test Done
This is a blood test. A clinician will fill a tube with blood taken from a vein in your arm through which a needle is inserted. If you are giving blood, a sample will be taken from the blood youre donating. The blood is sent to a lab, where it is tested. Sometimes HBcAb will be added on to lab orders when results from other tests indicate there may be a hepatitis B infection.
What Foods Should I Avoid
Everyone should avoid eating a lot of fat, cholesterol, salt and processed sugar, even if their liver is healthy. In addition, those with HCV should limit or avoid alcohol. Drinking alcohol will speed up liver damage.
Eating properly can help decrease some of the symptoms of Hepatitis C, like feeling tired and sick. Drink lots of water for general health benefits. HCV is not a digestive disease diet will not affect the disease. Your provider may put you on a special diet if you have advanced liver disease.

What Does Hepatitis B Envelope Antigen Mean
Hepatitis refers to liver inflammation caused by a viral infection. This is one of the most widespread and contagious diseases in the world with more than 400 million people being a carrier of the hepatitis B virus. When the hepatitis B virus is actively circulating and replicating in the blood, it produces the hepatitis B antigen protein. The presence of this antigen protein means that the person is infected with the virus and can spread the infection to other people.
How Is Hepatitis B Spread
You can become infected with hepatitis B through exposure to blood, semen and other bodily fluids of an infected person. You can get the infection by:
- Having unprotected sex.
- Sharing or using dirty needles for drug use, tattoos or piercing.
- Sharing everyday items that may contain body fluids, including razors, toothbrushes, jewelry for piercings and nail clippers.
- Being treated medically by someone who does not use sterile instruments.
- Being bitten by someone with the infection.
- Being born to a pregnant woman with the infection.
Hepatitis B is not spread by:
- Kissing on the cheek or lips.
- Coughing or sneezing.
- Hugging, shaking hands or holding hands.
- Eating food that someone with the infection has prepared.

Hepatitis B Surface Antibody Qualitative
Presence of antibody to hepatitis B surface antigen is used to determine immune status to HBV or disease progression in individuals infected with HBV. Anti-HBs levels can be measured to determine if vaccination is needed, or following a vaccination regimen, to determine if protective immunity has been achieved.
– Anti-HBs usually can be detected several weeks to several months after HBsAg is no longer found, and it may persist for many years or for life after acute infection has been resolved.
– It may disappear in some patients, with only antibody to core remaining.
– People with this antibody are not overtly infectious.
– Presence of the antibody without the presence of the antigen is evidence for immunity from reinfection, with virus of the same subtype.
What is the Hepatitis B virus?
Hepatitis B virus infection, also known as serum hepatitis, is endemic throughout the world. The infection is spread primarily through blood transfusion or percutaneous contact with infected blood products, such as sharing of needles among injection drug users. The virus is also found in virtually every type of human body fluid and has been known to be spread through oral and genital contact. HBV can be transmitted from mother to child during delivery through contact with blood and vaginal secretions, but it is not commonly transmitted via the transplacental route.
The incubation period for HBV infection averages 60 to 90 days .

What Are The Risk Factors For Getting Hepatitis B
Due to the way that hepatitis B spreads, people most at risk for getting infected include:
- Children whose mothers have been infected with hepatitis B.
- Children who have been adopted from countries with high rates of hepatitis B infection.
- People who have unprotected sex and/or have been diagnosed with a sexually transmitted infection.
- People who live with or work in an institutional setting, such as prisons or group homes.
- Healthcare providers and first responders.
- People who share needles or syringes.
- People who live in close quarters with a person with chronic hepatitis B infection.
- People who are on dialysis.

A note from Cleveland Clinic
Hepatitis B is a liver disease that can cause serious damage to your health. One reason that is dangerous is that it can easily go undetected for years while damaging your liver. Talk with your healthcare provider about being tested for hepatitis B if you have any reason to believe that you were not vaccinated or if you have engaged in risky behavior. If you do test positive, follow the directions from your healthcare provider so that you can live a longer, healthier and happier life.

Results Of The Hbcab Test
There are two variations of antibodies. The IgM antibody is the largest antibody and the first produced in an infection. It shows that you may have a current, active infection. Sometimes it persists for years, but it usually drops to undetectable levels.
The HBcAb IgG variant is produced later in the course of the infection, and its likely that you will have a positive HBcAb IgG test the rest of your life.
The screening panel usually has a test that is for total HBcAb, which includes both IgM and IgG. The IgM test may be ordered to help determine if you have an acute infection.
A positive HBcAb test must be interpreted along with the results of the other tests. You may have an active or chronic infection, or you may be immune to hepatitis B due to past infection. Discuss the results with your healthcare provider. In any case, a positive HBcAb test means your blood or organs cannot be donated to a recipient.

Is Hepatitis B Contagious
Hepatitis B is highly contagious. Its transmitted through contact with blood and certain other bodily fluids. Although the virus can be found in saliva, its not transmitted through sharing utensils or kissing. Its also not transmitted through sneezing, coughing, or breastfeeding.
Symptoms of hepatitis B may not appear for 3 months after exposure. Symptoms can last for several weeks.
But even without symptoms, you can still transmit the infection to others. The virus can live outside the body and remains infectious for at least
Hepatitis B is a highly contagious condition. Its associated with many serious complications, some of which can be life threatening.
But there are many treatment options available and multiple ways you can prevent infection, including getting vaccinated.
If you suspect you may have been exposed to hepatitis B, its important to talk with a doctor to prevent infection and determine the best course of treatment for you.
What Are My Next Steps Once I Get My Results
It can be difficult to understand what the results of your test mean. A healthcare provider can help you interpret your results and decide whether you need to take further action:
- If your results suggest that youre already immune to hepatitis B and arent contagious, you likely wont need to do anything.
- If your results suggest that youre not immune, a doctor may recommend vaccination, especially if youre somebody whos at a high risk of infection.
You may also need additional testing if more information is needed to interpret your results.

Taking A Hepatitis B Test
Testing for hepatitis B is performed on a sample of blood. A doctor, nurse, or other health care provider can obtain a blood sample using a small needle to draw blood from a vein.
At-home hepatitis B testing requires that users carefully follow instructions provided in the test kit to collect a small sample of blood, package the sample, and mail it to a lab for testing.
What Does A Reactive Result To A Hepatitis B Test Mean
The meaning of a reactive result for a hepatitis B test depends on the type of test performed, according to the Hepatitis B Foundation. The three most common blood tests detect the presence of hepatitis B surface antigens, hepatitis B surface antibodies or hepatitis B core antibodies.
In the hepatitis B surface antigen test, a reactive or positive result means that a person is currently infected with the hepatitis B virus, explains the Hepatitis B Foundation. Reactive results from the hepatitis B surface antibody test means that people are now immune to the virus because they have been infected in the past and their immune systems produced antibodies to fight the infection. For the hepatitis B core antibody test, a reactive or positive result can mean either that a person is currently infected with hepatitis B virus or have been some time in the test. A reactive result for this test can also be a false positive, meaning that the person has never been infected with the virus.
Can Hepatitis B Be Prevented
The hepatitis B vaccine is one of the best ways to control the disease. It is safe, effective and widely available. More than one billion doses of the vaccine have been administered globally since 1982. The World Health Organization says the vaccine is 98-100% effective in guarding against the virus. Newborns should be vaccinated.
The disease has also been more widely prevented thanks to:
- Widespread global adoption of safe blood-handling practices. WHO says 97% of the blood donated around the world is now screened for HBV and other diseases.
- Safer blood injection practices, using clean needles.
- Safe-sex practices.
You can help prevent hepatitis B infections by:
- Practicing safe sex .
- Never sharing personal care items like toothbrushes or razors.
- Getting tattoos or piercings only at shops that employ safe hygiene practices.
- Not sharing needles to use drugs.
- Asking your healthcare provider for blood tests to determine if you have HBV or if you are immune.
