Hepatitis A & B

How Can I Get Tested For Hepatitis B/HBV?

April 5, 2018

There aren’t any blood tests for Hepatitis B. One tests for the virus itself, and 2 test to your body’s reaction to this virus. Sometimes your healthcare provider will do all three tests since they inform her different items.

  • If you’re favorable for the antigen test (HBsAg) it means that you are currently infected with the virus and can move it to other. If you clear an HBV infection and don’t stay chronically infected, you will often test negative again within 4 weeks after your symptoms resolve.
  • If you’re positive on the anti-HBs test, which looks to your own body’s response to a surface protein of this virus, it means that you are immune to Hepatitis B. This may possibly be because you had been formerly exposed to the virus or as you were vaccinated. You cannot pass the virus to others.
  • If you are optimistic on the anti-HBc evaluation, which appears for your body’s response to a core protein of this virus, it usually means that you are chronically infected with HBV, and may pass the disease to other people. However, if you’re also positive on the anti-HBs test, then a positive anti-HBc test is likely because of a preceding infection.

Other tests may be ordered if your doctor thinks you’re chronically infected with HBV. These evaluations are done to monitor the development of the disorder and its treatment – not to detect whether or not you are infected.

There’s a vaccine for hepatitis B. If you are at elevated risk for the disease, you should talk to your doctor about getting vaccinated against the virus.

Risk factors include multiple sex partners, a sexual partner with HBV, residing with a person with chronic HBV, a job which brings you in contact with human blood, injection drug use, and being a man who has intercourse with guys. Current vaccination guidelines suggest that all children must be vaccinated against HBV, along with high-risk adults who have not previously been vaccinated.
