Prevention Tips For Hepatitis B

Understanding Hepatitis B Serology Results

Hepatitis B Prevention Measures

Hepatitis B is a vaccine-preventable disease. More than 1 billion doses of the hepatitis B vaccine have been given worldwide, and it is considered to be a very safe and effective vaccine to protect infants, children and adults from hepatitis B. Learn more.

All sexual partners, family and close household members living with a chronically infected person should be tested and vaccinated. It is important to remember that hepatitis B is not spread casually! It is not spread by coughing, sneezing, hugging, cooking and sharing food. It is spread through direct contact with infected blood and bodily fluids.

Additional Prevention Measures

In addition to vaccination, there are other simple ways to help stop the spread of hepatitis B:

  • Wash your hands thoroughly with soap and water after any potential exposure to blood
  • Use condoms with sexual partners
  • Avoid direct contact with blood and bodily fluids
  • Clean up blood spills with a fresh diluted bleach solution
  • Cover all cuts carefully
  • Avoid sharing sharp items such as razors, nail clippers, toothbrushes, and earrings or body rings
  • Discard sanitary napkins and tampons into plastic bags
  • Avoid illegal street drugs
  • Make sure new, sterile needles are used for ear or body piercing, tattoos, and acupuncture

What Does The Test Measure

Hepatitis B testing looks for antigens, antibodies, or the genetic material of the hepatitis B virus. HBV antigens are substances from the virus that cause a patientâs body to produce an immune response. Antibodies are substances made by the immune system in response to the hepatitis B virus.

Initial tests for hepatitis B measure antibodies and antigens related to HBV including:

If a patient is diagnosed with hepatitis B based on these initial tests, additional hepatitis B testing may be used to monitor the disease, guide treatment, and determine if a person can spread hepatitis B to others. These additional tests may include:

  • Hepatitis B e antigen : Hepatitis B e antigen is a protein from the hepatitis B virus found in some patients who are positive for hepatitis B surface antigen. Measuring this antigen can help doctors understand infectivity, which describes a personâs ability to spread HBV to others.

Specimen: Serum or plasma

Container: Red-top tube, yellow-top tube , gel-barrier tube, plasma preparation tube, or lavender tube

Collection method: Routine venipuncture

The specimen should be transfused to separate plasma/serum from cells within 6 hours and kept frozen when testing cannot be done promptly.

The tests use PCR amplification, DNA probe hybridization, and sequencing method.

Hepatitis B Surface Antibody Quantitative

The hepatitis B surface antibody is the antibody that is produced in response to hepatitis B surface antigen , a protein present on the surface of the hepatitis B virus. Anti-HBs appears after convalescence from acute infection and lasts for many years. It can also be produced in response to hepatitis B vaccination.

Screening Tests For Hepatitis B

Hepatitis B Treatment

Your blood may be screened for HBV for many different reasons. The three tests generally include HBsAg, antibody to HBsAg, and antibody to hepatitis B core antigen. This allows the healthcare provider to know whether you could benefit from vaccination, or if you have active or chronic hepatitis B and need counseling, care, or treatment.

You may be routinely screened if you are pregnant, are donating blood or tissue, need immunosuppressive therapy, or have end-stage renal disease. You will also be screened if you are in groups that are at higher risk for HBV.

What Does Reactive Result Mean In Hepatitis B

I was diagnosed as HEPATITIS B carrier in 2013 with fibrosis of the

liver already present. I started on antiviral medications which

reduced the viral load initially. After a couple of years the virus

became resistant. I started on HEPATITIS B Herbal treatment from

ULTIMATE LIFE CLINIC in March, 2020. Their

treatment totally reversed the virus. I did another blood test after

the 6 months long treatment and tested negative to the virus. Amazing

treatment! This treatment is a breakthrough for all HBV carriers.

What Does Hepatitis B Core Positive Mean

If your blood tests show that you are hepatitis B core body positive, it means that you either have a present infection or that you were infected in the past. There is a possibility of having a false hepatitis B core antibody positive.

What does reactive hepatitis B mean?

A: Hepatitis B Surface Antigen is one of the standard blood tests used to measure hepatitis B virus . When the test result is positive or reactive, it means the person is currently infected with hepatitis B and is able to pass the infection on to others through blood and other body fluid.

More Detailed Information About Hepatitis B Blood Tests

An acute hepatitis B infection follows a relatively long incubation period – from 60 to 150 days with an average of 90 days. It can take up to six months, however, for a person to get rid of the hepatitis B virus. And it can take up to six months for a hepatitis B blood test to show whether as person has recovered from an acute infection or has become chronically infected .

The following graphic from the U.S. Centers for Disease Control and Prevention represents the typical course of an acute hepatitis B infection from first exposure to recovery.

According to the CDC, a hepatitis B blood test result varies depending on whether the infection is a new acute infection or a chronic infection.

Addressing Hepatitis For The First Time

It is crucial that a treatment counselor or health professional use a nonjudgmental and compassionate tone. Clients need to feel comfortable disclosing information about their health and risky behaviors. The following strategies can help initiate the conversation:

  • Display posters, literature, or other -related items that could help prompt the client to ask questions about hepatitis. .
  • Assess clients ability to discuss , based on their degree of openness in the counseling session, the amount of detail they provide in their responses, and the length of the therapeutic relationship.
  • Raise the subject in a way that avoids making clients feel defensive or afraid. Consider introducing the subject by making parallels with other conditions that have been discussed. Say, for example, You said you were tested for HIV several times. Were you ever tested for viral ? or You mentioned that your friend is sick with HIV. Have you been tested for HCV or HIV? Tell me about those tests.
  • Be patient and allow time for multiple, short conversations about the subject. This might ease feelings of fear, anxiety, or shame.

What Is Hepatitis B Core Ab

Hepatitis B core antibodies appear shortly after the onset of symptoms of hepatitis B infection and soon after the appearance of hepatitis B surface antigen . Initially, anti-HBc Ab consist almost entirely of the IgM class, followed by appearance of anti-HBc IgG , for which there is no commercial diagnostic assay.

Hepatitis B And Pregnancy

Antibody to Hepatitis B Surface Antigen

Hepatitis B can be transmitted from a birthing parent to a newborn infant. This is because the newborn is exposed to blood and bodily fluids during delivery.

In fact, 90% of mothers with an acute hepatitis B infection and 10% to 20% of mothers with chronic hepatitis B will transmit the virus to their newborn, estimates the American College of Obstetricians and Gynecologists.

For this reason, birthing parents are routinely screened for hepatitis B during each pregnancy.

Additionally, the hepatitis B vaccine and hepatitis B immune globulin are both administered to infants with an HBV-positive birthing parent within of birth to prevent infection.

According to the

  • people with hepatitis C infection
  • men who have sex with men
  • people with multiple sexual partners
  • people who are seeking treatment for a sexually transmitted infections
  • people with current or recent injection drug use
  • family members or sexual partners of those with hepatitis B
  • people with chronic liver disease
  • people traveling to areas with high rates of hepatitis B
  • people on maintenance dialysis
  • people who are incarcerated

The hepatitis B vaccine is usually administered in three shots, given 1 month and 6 months after the first dose. Another recently approved vaccine is completed in two doses spaced 1 month apart.

Hi Everich,

You need to be a bit more specific about what the exact test was. What is all the information you have about the test? We cannot answer your question without that information.

Thomas

Hi Everich, there are basically 3 blood tests that are required for a new vs. a chronic hepatitis B infection. Below is a simple summary of these tests. If you could let us know which blood test was indeterminate that would be very helpful.

Hepatitis B surface antigen – If or means the hep b virus is present. This could mean a new infection or a chronic infection . If this test is or , then the hep b virus is not present in the blood.

Hepatitis B surface antibody – this tests for a protective antibody against the hep b virus. This can occur through getting the hep b vaccine or recovery from an exposure to the virus. If or , then it means a person has been protected against the hep b virus either through vaccination or recovery from an infection. Generally, the above test will be or .

What Is The Name Of The Hepatitis B Surface Antibody Test

The hepatitis B surface antibody test , looks for antibodies that your immune system makes in response to the surface protein of the hepatitis B virus. The hepatitis B surface antibody is also referred to as anti-HBs and should not be confused with HBsAg, which stands for hepatitis B surface antigen .

What does HBeAg mean on a hepatitis B blood test?

HBeAg is generally detectable in patients with a new acute infection the presence of HBeAg is associated with higher HBV DNA levels, thus, increased infectiousness. IgM anti-HBc a positive blood test result indicates a person has a new acute hepatitis B

What does it mean to not have Hep B?

It means that you have never been exposed to the Hepatitis B virus, so you do not have the virus. Patients that have never been exposed to the hepatitis B virus should consider receiving vaccination for hepatitis B , so they can not catch this infection in the future.

When Should I Get Hepatitis B Testing

Using hepatitis B tests to screen for HBV is recommended for certain groups that are at an increased risk of infection. Groups that may benefit from hepatitis B screening include:

  • Pregnant people
  • People born in parts of the world where hepatitis B is more common, including Africa, Asia, Eastern Europe, South America, and parts of the Middle East
  • People who didnât receive a hepatitis B vaccine
  • HIV-positive people
  • Pain in the joints or abdomen
  • Loss of appetite, nausea, or vomiting
  • Yellowish skin and eyes

Using hepatitis B testing to assess immunity to HBV may be used before or after vaccination. Pre-vaccination testing is not always needed but may be performed if there is a chance that a patient has previously been infected with HBV or has already been vaccinated. Post-vaccination testing is used in certain groups of people who are at an especially elevated risk for HBV infection, including infants born to mothers with a hepatitis B infection.

Hepatitis B can very easily escape diagnosis, as most victims do not know they are suffering can spread the disease. This is because symptoms are almost negligible during the onset of hepatitis B infection. Although the infection is treatable and largely preventable, yet early diagnosis can go a long way in the better prognosis of the condition. Further, even though there are good treatment options for hepatitis B, close to a million people with the infection do not make it.Asian countries portray a high prevalence of hepatitis B. This infection is very common among high-risk groups such as people with multiple sex partners, homosexuals, injection drug users or people staying lose to victims of Hepatitis B.

What Is The Purpose Of A Hepatitis B Test

Hepatitis B test is performed to detect, classify, and treat hepatitis B virus infection.

Hepatitis B blood tests involve the measurement of several HBV-specific antigens and antibodies. In addition, HBV blood tests also include liver enzymes and liver function tests to assess and monitor the condition of the liver and provide appropriate treatment.

The HBV specific tests include the following:

  • HBsAg: HBsAg is an antigen found on the surface of hepatitis B virus. HBsAg may be detected in the blood any time after 1 week post-exposure to HB virus, but usually appears after 4 weeks.
  • Anti-HBs: Anti-HBs are antibodies produced by the bodys immune system to fight HBsAg. Anti-HBs from a prior infection or vaccination provides immunity against further infection.
  • Hepatitis B core antigen : HBcAg is an antigen found in the core layer which covers the hepatitis B viral DNA.
  • Hepatitis B core antibody : Anti-HBc is the antibody that fights HBcAg. Anti-HBc is the first detectable antibody after HBV infection. There are two kinds of Anti-HBc:
  • Immunoglobulin M hepatitis B core antibody : IgM anti-HBc indicates acute or reactivated recent infection within the previous 6 months.
  • Immunoglobulin G hepatitis B core antibody : IgG anti-HBc may indicate previous or chronic infection. Once present, IgG anti-HBc persists for a lifetime.
  • HBV DNA: HBV DNA is the genetic material of the HB virus and this test is a measure of the actual viral load and replication.

    What if I have a false reactive test result?

    Every donation given to Canadian Blood Services is tested for infectious diseases caused by the hepatitis viruses B and C, HIV, syphilis and another uncommon virus called HTLV .

    A false reactive test result means your initial screening test was reactivein other words, suggested the presence of something that would prevent you from donating bloodand a more precise follow-up test was negative. Almost all false reactive results occur because of interference with a test and are not necessarily due to testing positive for an infection.

    FAQS

    How does Canadian Blood Services test blood?

    We follow a two-stage testing method that is used in laboratories worldwide. In the first stage, a sensitive screening test looks for the possible presence of infection. If the screening test shows no reaction, the blood is considered free of infection and no further testing is done. However, if the screening test is reactive, further testing is done to sort out whether the reactive result was due to an infection in the blood or interference with the test. The second test identifies markers in the blood that are found only when infection is present.

    Do I need to go to my doctor for repeat testing?

    Yes. Repeat testing should be discussed with your doctor because he/she is in the best position to offer you personal medical advice.

    Do my partner, children, or friends need to worry if Ive had a false reactive result?
