The Hepatitis B Surface Antibody, Quantitative test contains 1 test with 1 biomarker.
Description: Hepatitis B Surface Antibody, Quantitative is a test that will determine if there are Hep B antibodies present in the blood.
Also Known As: Hep B Test, Hep B Surface Antibody Test, Hep B Antibody Test, Hepatitis B Antibody Test, Hep B Surface Ab Test, HBV Antibody Test, HBV Surface Antibody Test
Collection Method: Blood Draw
Specimen Type: Serum
Test Preparation: No preparation required
Average Processing Time: 1 to 2 days
When is a Hepatitis B Surface Antibody Quantitative test ordered:
Hepatitis B antibody testing is generally ordered to determine immunity to Hepatitis B through the detection of antibodies in the blood. This testing is often requested for medical records related to school and healthcare professions.
What does a Hepatitis B Surface Antibody Quantitative blood test check for?
Antibodies to the hepatitis B virus are detected in hepatitis B antibody tests, which indicate a past infection or immunization against the virus.
Hepatitis is a liver infection that causes inflammation and enlargement. It can be caused by a number of factors, one of which is virus infection. HBV is one of five "hepatitis viruses" known to primarily infect the liver that have been found thus far. Hepatitis A, hepatitis C, hepatitis D, and hepatitis E are the other four.
HBV is disseminated through coming into touch with an infected person's blood or other bodily fluids. For example, exposure can occur through the sharing of IV drug needles or through unprotected intercourse. People who reside in or travel to places of the world where hepatitis B is common are more vulnerable. Mothers can spread the virus to their newborns on a rare occasion, generally during or after delivery. The virus is not spread through simple hand-to-hand contact, coughing, or sneezing. The virus, however, can survive for up to seven days outside the body, including in dried blood, and can be spread by sharing razors or toothbrushes with an infected individual.
Effective hepatitis B vaccines have been available in the United States since 1981, and health care providers began immunizing infants at birth in 1991. Despite this, the CDC believes that between 804,000 and 1.4 million persons in the United States are infected with the virus, the majority of whom are unaware of their infection.
HBV infections can range in severity from a mild infection that lasts a few weeks to a more dangerous chronic infection that lasts years. Chronic HBV can sometimes lead to significant problems including cirrhosis or liver cancer.
The great majority of people who have chronic infections don't show any signs or symptoms. The symptoms of acute infections are remarkably similar to other types of acute hepatitis. Fever, tiredness, nausea, vomiting, and jaundice are some of the symptoms. The liver is damaged and unable to function normally in acute hepatitis. It may not be able to remove toxins or waste products like bilirubin from the body. Bilirubin and liver enzyme levels in the blood may rise as the disease progresses. While tests like bilirubin and a liver panel can tell a doctor if someone has hepatitis, they can't tell them what's causing it. Tests for hepatitis virus infection may aid in determining the cause.
Lab tests often ordered with a Hepatitis B Surface Antibody Quantitative test:
- Hepatitis A antibody test
- Hepatitis C antibody test
- Acute Viral Hepatitis Panel
- Hepatic Function Panel
- Bilirubin Fractionated
- Comprehensive Metabolic Panel
- Gamma-Glutamyl Transferase
Conditions where a Hepatitis B Surface Antibody Quantitative test is recommended:
How does my health care provider use a Quantitative 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 Hepatitis B 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.
We advise having your results reviewed by a licensed medical healthcare professional for proper interpretation of your results.
