    Hepatitis C is a viral infection in the liver caused by the hepatitis C virus, or HCV. It is spread through contact with blood from an infected person. Today, most people become infected with the virus by sharing needles or through equipment used to prepare or inject drugs. However, it can also be spread through birth from an infected mother to child, through sexual contact, sharing personal items contaminated with blood such as razors and toothbrushes, unregulated tattooing, and some health care procedures such as injections, infected blood transfusions , and needlestick injuries in healthcare settings.

    The immediate period following infection is called the acute phase and lasts approximately six months. Many people do not experience symptoms during this phase, or if they do, they show non-specific symptoms such as fatigue, loss of appetite, and depression.

    After six months, approximately 70%-85% of those infected with HCV will fail to clear the virus on their own, or spontaneously, and this is when hepatitis C becomes a chronic or long-term infection. This high rate showcases the importance of regular testing so that treatment, which is highly effective, can start right away.

    Hepatitis A Infection Is Typically Diagnosed Through Blood Tests

    The various human hepatitis viruses cause very similar symptoms. Therefore, neither the individual nor the healthcare provider can tell by symptoms or signs if a given individual is suffering from hepatitis A unless laboratory tests are performed.

    Fortunately, blood tests are widely available to accurately diagnose hepatitis A, including tests for antibodies, or the affected persons immune response to hepatitis A proteins. This immune response is conclusively demonstrated by the presence of Immunoglobulin M antibodies, indicating acute disease, and immunoglobulin G , indicating a past infection or vaccination. The IgG antibodies are present for life, indicating immunity.

    HAV RNA is present in blood and feces soon after infection , until 1 to 2 weeks after the onset of symptoms. Longer shedding in feces can occur in children and those infected with HIV. HAV is also shed in saliva and urine, but no assays are available to detect this.

    Following is some guidance for the interpretation of the test results:

    Previous Chapter

    How Is Hepatitis A Transmitted

    Hepatitis A can be acquired or spread when an unvaccinated, or not immune, person consumes infected fecal matter. This is most commonly done by eating or drinking contaminated food or water.

    Risk factors for hepatitis A:4)

    • Live with or are caregivers to someone with hepatitis A
    • Have eaten contaminated food or drank contaminated water
    • Travel to areas of low/poor sanitation
    • Have had sexual contact with someone who has the virus
    • Have eaten food prepared by someone with the virus who doesnt thoroughly wash their hands after using the restroom

    No. After three intramuscular doses of vaccine, > 90% of healthy adults and > 95% of those < 19 years of age develop immunity .1 However, there is an age-specific decline in development of immunity. After age 40 years, about 90% of people become immune, but by age 60 years, only 75% of people become immune.1 Larger vaccine doses or an increased number of doses are required to induce immunity in many hemodialysis patients and in other immunocompromised people.1

    What Does The Test Measure

    Positive hepatitis B surface antigen tests due to recent vaccination: a ...

    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 patients 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 persons ability to spread HBV to others.

    How Long Do Hep B Antibodies Last

    How long does protection from hepatitis B vaccine last? Studies indicate that immunologic memory remains intact for at least 30 years among healthy people who initiated hepatitis B vaccination at > 6 months of age. The vaccine confers long-term protection against clinical illness and chronic hepatitis B virus infection.

    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 Do My Test Results Mean

    Test results may vary depending on your age, gender, health history, the method used for the test, and other things. Your test results may not mean you have a problem. Ask your healthcare provider what your test results mean for you.

    Normal results are negative or nonreactive, meaning that no hepatitis B surface antigen was found.

    If your test is positive or reactive, it may mean you are actively infected with HBV. In most cases this means that you will recover within 6 months. If you recover, you will have immunity from the virus and will not be able to pass the virus to others. A positive test may also mean you have chronic hepatitis B infection. If you dont recover in 6 months, the virus may stay in your blood and cause liver problems. You can also infect others. Your healthcare provider may give you medicines if you dont recover after 6 months.

    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.

    Why It Is Done

    You may need testing if:

    • You have symptoms of hepatitis.
    • You may have been exposed to the hepatitis B virus. You are more likely to have been exposed to the virus if you inject drugs, have many sex partners, or are likely to be exposed to body fluids .
    • You’ve had other tests that show you have liver problems.
    • You are pregnant.
    • You or your doctor wants to know if you are protected from getting the disease.

    The tests also are done to help your doctor decide about your treatment and see how well it’s working.

    How The Test Is Performed

    Kinetics of viral loads and risk of hepatitis B virus reactivation in ...

    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.

Are you infected? Protected? Or at risk? The Hepatitis B Panel of blood tests includes 3 tests and all three results must be known in order to confirm your status.

    Below is a chart with the most common explanation of the test results, but unusual test results can occur. Please note that this chart is not intended as medical advice, so be sure to talk to your health care provider for a full explanation and obtain a printed copy of your test results. In some cases, a person could be referred to a liver specialist for further evaluation.

    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.
