Hepatitis B Testing

Hepatitis B can result in two different types of infection; acute infection where it lasts for only a few weeks, or chronic hepatitis B which is a serious, lifelong illness. 

Acute infection may not result in any symptoms, but for those that do, symptoms of acute hepatitis B include: 

1. Fever
2. Fatigue
3. Loss of appetite
4. Nausea
5. Vomiting
6. Abdominal pain
7. Dark urine
8. Clay-colored bowel movements
9. Joint pain
10. Jaundice 

Most individuals with chronic hepatitis won’t have any symptoms, and may not develop any for decades. Once symptoms do develop, they will be similar to those with an acute infection, but may indicate advanced liver disease. Chronic hepatitis B can develop into other serious health issues like liver damage, liver failure, liver cancer, and even death.

A simple blood test is all that is required to determine whether or not you have hepatitis B. However, there are several tests available that can determine whether you have chronic or acute infection, are immune after vaccination, or may have been infected in the past but have cleared the virus naturally. There are even tests that could determine how easily you can pass hepatitis B to others if you are infected. When ordered by a physician, the hepatitis B test involves a 3-part blood panel that screens for the presence of antigens and/or antibodies that will provide these answers.

Because of the test complexity, results are typically returned within 7 to 10 days after the lab receives your sample.

There are no medications currently to treat acute hepatitis B. If you are experiencing mild symptoms, you may simply receive recommendations to rest, consume proper nutrition, and hydrate. If there are more severe symptoms, you may need to be hospitalized. 

Chronic hepatitis B can be treated with several medications. These may not be viable options for all individuals due to potential side effects, but those who do take medication will most likely need to take it for the rest of their lives as there is no cure. You will need to work closely with your healthcare provider to regularly monitor liver function and follow healthy lifestyle habits, such as avoiding alcohol, eating healthy, and staying active. 

The good news is, hepatitis B can actually be prevented with vaccinations. All infants, those younger than 19 who have not already been vaccinated, adults aged 19 -59, and those aged 60 and older with certain risk factors should be vaccinated for hepatitis B. You will need to receive all shots within the vaccine series to achieve full protection against the virus.
