Normal Range Of Hepatitis B

How Is Hepatitis B Treated

Your healthcare provider will treat you based on what type of hepatitis B you have, acute or chronic.

Acute hepatitis B infections

If you develop an acute form of the condition, you probably wont need medical treatment. Instead, your doctor will likely suggest that you get plenty of rest, drink lots of fluids and maintain a healthy diet to support your body as it fights off the infection.

Chronic hepatitis B infections

If you have chronic hepatitis B, you might be a candidate for drug therapy. Usually, drug therapy is used only if you have active liver disease. There are seven drugs that are approved by the U.S. Food and Drug Administration to treat hepatitis B. Two are injectable forms of interferon, while the five other antivirals are tablets.

You will need to take these medications every day. They help by slowing the viruss ability to multiply in your system. This helps reduce swelling and liver damage. Youll need to be regularly monitored for early signs of liver damage and liver cancer. Your healthcare provider will want to see you once or twice a year.

Hepatitis B And Pregnancy

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.

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.

How Common Is Hepatitis B

Hepatitis B is fairly common in Africa and the western Pacific region. Throughout the world, there are about 292 million people who are infected with chronic hepatitis B. In the U.S., the figure exceeds 2 million people.

The number of infections had been falling in the U.S., but fewer vaccinations among adults combined with the onset of the opioid crisis and injected drug usage has resulted in the numbers rising again. Infected women can pass the infection on to their babies. Children who are infected before age 5 are more likely to have chronic infection than those infected later in life.

How Is Hepatitis B Spread

• 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.

How The Test Is Performed

Blood is most often drawn from a vein from the inside of the elbow or the back of the hand. The site is cleaned with germ-killing medicine . The health care provider wraps an elastic band around the upper arm to apply pressure to the area and make the vein swell with blood.

Next, the provider gently inserts a needle into the vein. The blood collects into an airtight tube attached to the needle. The elastic band is removed from your arm. Once the blood has been collected, the needle is removed. The puncture site is covered to stop any bleeding.

In infants or young children, a sharp tool called a lancet may be used to puncture the skin and make it bleed. The blood collects into a small glass tube, or onto a slide or test strip. A bandage may be placed over the area if there is any bleeding.

The blood sample is sent to a lab to be examined. Blood tests are used to check for antibodies to each of the hepatitis viruses.

Is There A Cure For Chronic Hepatitis B

Currently, there is no complete cure for hepatitis B. But when managed properly, those living with the virus can expect to live a normal life. Maintaining a healthy diet and avoiding beverages that contain alochol and tobacco products are crucial components in managing the disease.

You should also visit a doctor familiar with hepatitis B at least annually though twice a year might be best to monitor your liver through blood tests and medical imaging. As with most diseases, detecting it early leads to a better outcome. If youre exposed to the virus, you should get an antibody injection within 12 hours of exposure.

How Is Hepatitis B Diagnosed

There are three main ways to diagnose HBV infection. They include:

• Blood tests: Tests of the blood serum shows how your bodys immune system is responding to the virus. A blood test can also tell you if you are immune to HBV.
• Abdominal ultrasound: An ultrasound uses sound waves to show the size and shape of your liver and how well the blood flows through it.
• Liver biopsy: A small sample of your liver tissue is removed though a tiny incision and sent to a lab for analysis.

The blood test that is used to diagnose hepatitis B is not a test that you get routinely during a medical visit. Often, people whove become infected first learn they have hepatitis B when they go to donate blood. Blood donations are routinely scanned for the infection.

The virus can be detected within 30 to 60 days of infection. About 70% of adults with hepatitis B develop symptoms, which tend to appear an average of 90 days after initial exposure to the virus.

The Hep B Blood Tests

There are 3 hep B tests called HBsAg, anti-HBs, and anti-HBc. You should make sure your doctor does all three hep B tests. Our hep B testing chart can explain each test and help you to make sure your doctor does all the tests you need.

These three tests tell you if you have hep B, if you are protected against hep B , and if you have ever come into contact with hep B. Getting all three tests is important to helps you and our doctor understand your hep B status.

What Are The Treatments For Hepatitis B

If you think you may have been exposed to hepatitis B, its important to talk with a healthcare professional as soon as possible.

A doctor or other healthcare professional may administer the first dose of the hepatitis B vaccine and a shot of hepatitis B immunoglobulin. This is a combination of antibodies that provide short-term protection against the virus.

Though both can be given up to a week after exposure, theyre most effective at preventing infection if administered within 48 hours.

If you receive a diagnosis of acute hepatitis B, a doctor may refer you to a specialist. They may advise you to get regular blood tests to ensure you dont develop chronic hepatitis.

Many people with acute hepatitis B dont experience serious symptoms. But if you do, it can help to:

• get plenty of rest
• take over-the-counter pain mediation, like naproxen, when needed

Other lifestyle changes may also be needed to manage your infection, such as:

• eating a nutritious, balanced diet
• avoiding substances that can harm your liver, such as:

• certain herbal supplements or medications, including acetaminophen

If blood tests show you still have an active infection after 6 months, your doctor may recommend further treatment, including medications to help control the virus and prevent liver damage.

What Is The Outlook For People With Hepatitis B

The outlook for people with HBV is better now than ever before. You are certainly able to live a full life and help yourself stay healthy. You should make sure to have regular check-ups with a healthcare provider who is qualified to treat hepatitis B, possibly a liver doctor.

Make sure you are vaccinated against hepatitis A. Check with your healthcare provider or pharmacist before taking other medications or over-the-counter products, including supplements and natural products. These could interfere with your medication or damage your liver. For instance, taking acetaminophen in large doses may harm your liver.

Follow the usual guidelines for living a healthy life:

• Eat nutritious foods, choosing from a variety of vegetables, fruits and healthy proteins. It is said that cruciferous vegetables are especially good at protecting the liver.
• Exercise regularly.
• Dont smoke and dont drink. Both tobacco and alcohol are bad for your liver.
• Do things that help you cope with stress, like journaling, talking with others, meditating and doing yoga.
• Avoid inhaling toxic fumes.

What Is The Normal Range For Hepatitis B Surface Antibody

Hepatitis B surface antibodies are measured in blood samples in milli-International Units/milliliter mIU/mL). The ranges for hepatitis B surface antibodies are:

• Anti-HBs greater than 10-12 mIU/mL: Protected against hepatitis B virus infection, either from vaccination or successful recovery from a previous HBV infection.
• Anti-HBs less than 5 mIU/mL: Negative for HBV infection, but susceptible and hence requires vaccination.
• Anti-HBs from 5-12 mIU/mL: Inconclusive results and the test should be repeated.

However, there is no standardization of these values so it is advisable to check the manufacturers values it is the reason values are mainly reported as positive or negative.

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 Do Hepatitis B Test Results Mean

Hepatitis B test results help determine if HBV infection is negative or positive, and if positive, whether the infection is acute or chronic, or if recovery is complete. A combination of results are considered to identify and classify HBV infection status.

The following are some interpretations of hepatitis B test results:

Table: Hepatitis B test results and interpretations

Hepatitis B Surface Antigen Test

A hepatitis B surface antigen test shows if you have an active infection. A positive result means you have hepatitis B and can transmit the virus to others. A negative result means you dont currently have hepatitis B.

This test doesnt distinguish between chronic and acute infection. This test is used together with other hepatitis B tests to determine the state of a hepatitis B infection.

Transmission Symptoms And Treatment

How is HBV transmitted?

HBV is transmitted through activities that involve percutaneous or mucosal contact with infectious blood or body fluids , including

• sex with a partner who has HBV infection
• injection drug use that involves sharing needles, syringes, or drug-preparation equipment
• birth to a person who has HBV infection
• contact with blood from or open sores on a person who has HBV infection
• exposures to needle sticks or sharp instruments and
• sharing certain items with a person who has HBV infection that can break the skin or mucous membranes , potentially resulting in exposure to blood.

How long does HBV survive outside the body?

HBV can survive outside the body and remains infectious for at least 7 days .

What should be used to clean environmental surfaces potentially contaminated with HBV?

Any blood spills should be disinfected using a 1:10 dilution of one part household bleach to 9 parts water. Gloves should be worn when cleaning up any blood spills.

Who is at risk for HBV infection?

The following populations are at increased risk for becoming infected with HBV:

• Infants born to people with HBV infection
• Sex partners of people with HBV infection
• Men who have sex with men
• People who inject drugs
• Household contacts or sexual partners of known people with chronic HBV infection
• Health care and public safety workers at risk for occupational exposure to blood or blood-contaminated body fluids
• Patients on hemodialysis

Who should be screened for HBV?

Does Hepatitis B Show Up In Routine Blood Tests

Routine blood tests do not detect hepatitis B virus infection. Hepatitis B tests are specifically done if blood tests show abnormal liver function results, or if a person experiences symptoms or falls into the high-risk category for HBV infection.

A panel of HBV-specific blood tests are required to detect HBV infection.

Is Hepatitis B Curable

Theres currently no known cure for hepatitis B, but there are many ways you can prevent infection and avoid transmitting the virus to others.

The most effective and safe way to prevent hepatitis B is to get vaccinated. You can also use barrier methods, like condoms, when having sex and avoid sharing needles.

How Can I Get A Hepatitis B Test

Hepatitis B testing is typically prescribed by a doctor and performed in a hospital, lab, or another medical setting. Taking a hepatitis B test requires a blood sample, which can be collected by a health care professional.

For laboratory-based testing, blood is drawn from your vein. After blood is collected, the sample is sent to a laboratory for analysis.

The test can also be ordered online and is available through our shop page.

How Much Does A Hepatitis B Titer Test Cost

The cost of a hepatitis B test varies based on where you get the test. Prices range from roughly $24 to $110.

Your insurance may cover some or all of the cost. Under the Affordable Care Act, all new health plans must cover preventative services including hepatitis B vaccination and testing without a deductible or copay.

Who Are Hepatitis B Carriers

Hepatitis B carriers are people who have the hepatitis B virus in their blood, even though they dont feel sick. Between 6% and 10% of those people whove been infected with the virus will become carriers and can infect others without knowing it. There are over 250 million people in the world who are carriers of HBV, with about 10% to 15% of the total located in India. Children are at the highest risk of becoming carriers. About 9 in 10 babies infected at birth become HBV carriers, and about half of children who are infected between birth and age 5 carry the virus. A blood test can tell you if you are a hepatitis B carrier.

Why The Test Is Performed

Your provider may order this test if you have signs of hepatitis. It is used to:

• Detect current or previous hepatitis infection
• Determine how contagious a person with hepatitis is
• Monitor a person who is being treated for hepatitis

The test may be performed for other conditions, such as:

• Chronic persistent hepatitis

A normal result means no hepatitis antibodies are found in the blood sample. This is called a negative result.

Normal value ranges may vary slightly depending on the lab doing the test. Talk to your provider about the meaning of your specific test results.

When Should You Have The Test

Anyone who has symptoms of hepatitis B may benefit from having the test. Other people who may consider undergoing the hepatitis B panel test are those with known risk factors. These people include individuals born in places with a high incidence of HBV infection and those who use needles to inject drugs.

Hepatitis B Lab Tests

If you have chronic hepatitis B, your health care provider will usually order additional tests to determine whether the infection is active, such as:

• HBeAg and anti-HBe: HBeAg is the hepatitis B envelope antigen, and anti-HBe are the antibodies produced against this antigen. If HBeAg is detectable in a blood sample, this means that the virus is still active in the liver . If HBeAg is negative and anti-HBe is positive, this generally means that the virus is inactive. However, this is not always the case. Some people with chronic hepatitisespecially those who have been infected with HBV for many yearsmay have what is known as a precore or core variant mutated form of HBV. This can cause HBeAg to be negative and anti-HBe to be positive, even though the virus is still active in the liver.

• Liver function tests: One of the most important liver enzymes to look for is alanine aminotransferase , sometimes called SGPT on lab reports. An elevated ALT level indicates that the liver is not functioning properly and that there is a risk of permanent liver damage. During acute hepatitis B infection, ALT levels can be temporarily elevated, but this rarely leads to long-term liver problems. In chronic hepatitis B, ALT levels can be either periodically or consistently increased, indicating a higher risk of long-term liver damage.
