When is a Qualitative Hepatitis B Surface Antibody test ordered?

When someone exhibits acute hepatitis-related signs and symptoms, a hepatitis B test may be requested to evaluate whether the symptoms are caused by HBV infection.

When the findings of normal testing, such as ALT and/or AST, are increased, hepatitis B tests may be performed as a follow-up. Since they may only cause minor symptoms that can be mistaken for the flu, acute forms of hepatitis can occasionally be identified in this way. Chronic hepatitis is more frequently found when routine test results are abnormal and more frequently has no symptoms.

When a person is at high risk for developing chronic hepatitis B, a test for hepatitis B surface antigen may be utilized for screening.

Hepatitis B tests may be run on a regular basis to check on persons with chronic hepatitis B infections. Since HBeAg may disappear on its own in certain individuals, hepatitis B surface antigen and hepatitis B e antigen measurements are often performed every six to twelve months. HBeAg and HBV DNA testing can be used to evaluate the efficacy of treatment in patients with chronic HBV.

What does a Qualitative Hepatitis B Surface Antibody test check for?

Hepatitis B tests look for chemicals that indicate a recent or past hepatitis B virus infection. While some tests look for viral proteins or antibodies created in response to an infection, others look for or assess the virus' genetic makeup. A person who has immunity as a result of prior exposure or who now has an active infection can be determined by the pattern of test findings.

The symptoms of hepatitis include inflammation and liver enlargement. It can be caused by a number of different things, one of which is virus infection. One of the five "hepatitis viruses" that have been found thus far is HBV. Hepatitis A, hepatitis C, hepatitis D, and hepatitis E make up the remaining four.

Contact with blood or other bodily fluids from an infected person can transfer HBV. For instance, sharing needles for IV drug usage or having sex without protection can expose someone. Greater risk applies to people who reside in or travel to regions of the world where hepatitis B is common. Rarely, generally during or after birth, women might transmit the virus to their newborns. The virus cannot be spread by innocuous actions like shaking hands, coughing, or sneezing. However, the virus can survive outside the body for up to seven days, including in dried blood. It can also spread through the sharing of objects like toothbrushes or razors with an infected individual.

Effective hepatitis B vaccines have been available in the United States since 1981, and starting in 1991, medical professionals there started immunizing newborns. Nevertheless, according to the Centers for Disease Control and Prevention, the virus is present in between 804,000 and 1.4 million Americans, the majority of whom are unaware that they are infected.

HBV infections can range in severity from a brief, mild form to a more dangerous, chronic variant that lasts for years. Serious side effects from persistent HBV can occasionally include cirrhosis or liver cancer.

Acute HBV infection, albeit potentially dangerous, typically goes away on its own in most adults. Children and infants are more likely than adults to have a persistent infection. 90% of newborns with HBV infection go on to acquire a chronic illness. Between 25% and 50% of children between the ages of one and five are at risk of acquiring chronic hepatitis. Only 6% to 10% of HBV infections that start after age five progress to chronic disease.

Most people with persistent infections won't show any symptoms. The signs and symptoms of acute infections are quite similar to those of other acute hepatitis types. Fever, exhaustion, nausea, vomiting, and jaundice are among the symptoms. The liver is damaged and unable to function normally when someone has acute hepatitis. It might not eliminate toxins or waste materials from the body, such bilirubin. Bilirubin and liver enzyme levels in the blood may rise as the disease progresses. Although tests like bilirubin or a liver panel can show a doctor that a patient has hepatitis, they cannot tell them what is causing it. The cause may be found with tests that look for hepatitis virus infection.

Testing for hepatitis B can be done in the absence of symptoms, to identify if an infection is acute or chronic, or to keep track of a chronic infection and how well therapy is working.

Lab tests often ordered with a Qualitative Hepatitis B Surface Antibody test:

  • Hepatitis A Antibody Testing
  • Hepatitis C Antibody Testing

Conditions where a Qualitative Hepatitis B Surface Antibody test is recommended:

  • Hepatitis B
  • Hepatitis C
  • Liver Disease

How does my health care provider use a Qualitative Hepatitis B Surface Antibody test?

Antibody generated in response to HBV surface antigen is detected by hepatitis B surface antibody test. It is used to determine the necessity for immunization or if a person has recovered from an infection and is immune. It can also arise from effective vaccination.

What do my Qualitative Hepatitis B Surface Antibody test results mean?

If antibodies are not detected, it indicates that a person has not developed antibodies to the Hepatitis B Virus.

If antibodies are detected, it indicates that a person has developed antibodies to the Hepatitis B Virus.

Clinical Significance

The detection of anti-HBs is indicative of a prior immunologic exposure to the antigen or vaccine. To determine immune status as ≥10 mIU/mL as per CDC guidelines, please order Hepatitis B Surface Antibody, Quantitative.

We advise having your results reviewed by a licensed medical healthcare professional for proper interpretation of your results.
