Is it possible to have a positive result for HBsAg and anti HBs at the same time explain your answer?

In this case, the level of HBsAg and anti-HBs is usually very low, and the HBsAg/anti-HBs double-positive status might be transient. Previous studies have also reported HBsAg seroreversion (reappearance of HBsAg after HBsAg seroclearance) in patients who experienced HBsAg seroclearance with positive anti-HBs25,26.

What does it mean when you are HBsAg positive and HBeAg positive?

Serum levels of both HBeAg and HBsAg rise rapidly during the period of viral replication. The presence of HBeAg in serum correlates with hepatitis B virus (HBV) infectivity, the number of infectious virions, and the presence of HBV core antigen in the infected hepatocytes.

Can HBsAg and HBsAb be positive?

Both in vitro simulation and in vivo animal models demonstrated that HBsAg antigen and HBsAb of the same serotypes could not coexist, but HBsAg antigen and HBsAb of different serotype could coexist. HBsAg/HBsAb double positive hepatitis B virus infection could be due to infection of viruses of different serotypes.

What two hepatitis B Serologies must be present to diagnose an acute infection?

Diagnosis of hepatitis B infection Acute hepatitis B is a clinical diagnosis identified by the detection of HBsAg, symptoms, high serum aminotransferases.

Will you test positive for Hep B if you have been vaccinated?

Your body can make this antibody if you have been vaccinated, or if you have recovered from a hepatitis B infection. If this test is positive or “reactive,” then your immune system has successfully developed a protective antibody against the hepatitis B virus.

What does HBeAg positive mean?

The hepatitis e antigen, or HBeAg, is a marker of an actively replicating HBV virus infection. Those with a positive HBeAg have active replication in their liver cells, more of the virus circulating in their blood, and as a result, they are more infectious, with a higher likelihood of transmitting HBV to others.

Can I donate blood if I have hepatitis B antibodies?

People infected with hepatitis B may carry the virus without even knowing it. They can pass it to others through blood or sexual contact. Because of this, anyone who has ever tested positive for hepatitis B cannot donate blood.

Can I get Covid vaccine if I have hepatitis B?

I’m on treatment for hep B, can I still get the COVID vaccine? YES. There is no evidence to suggest that the COVID-19 vaccines have any impact on your hep B treatment. Just like with all other vaccines, the COVID vaccines are safe for people on hep B treatment.

When do you test for Hep B antibodies after vaccination?

Postvaccination testing should be done 1–2 months after the last dose of hepatitis B vaccine. If adequate anti-HBs is present (>10mIU/mL), nothing more needs to be done.
