Exposed To Hepatitis B But Tested Negative. Got Jaundice, Then Tested Positive For Hepatitis B. How Could It Happen ?

Hi, I was exposed to hepatitis B back in March through sexual contact, my test came back negative across the board. Then on June 6 I was admitted to the hospital due to being jaundice, I was tested again for Hepatitis B and I tested positive. I was wondering how that could be since I didn't have any further contact once I found out what the guy had. Could you please tell me how this could happen? No one else has been able to including all of my Drs I see. Thank you

Hello Good Evening,

Answer of your query is quite simple as follows:

Hepatitis B infection is detected on screening by HBsAg (Hepatitis Virus Surface Antigen), which detected in an infected person’s blood an average of 4 weeks (range: 1–9 weeks) after exposure to the virus.
So you might be tested prior to that period.

The incubation period (time gap between entry of pathogen to the body and first appearance of signs and symptoms) of the hepatitis B virus is 90 days on average, but can vary from 30 to 180 days.
So you became symptomatic after around 3 months of being infected.

So you should be agree that you are positive for Hepatitis B and be in regular follow up of your GP to control your disease.

Regards.
