MCQ on Virology: Hepatitis and related Viruses

In this blog, I have posted few multiple choice questions regarding Hepatitis Virus properties, lab diagnosis, vaccine etc. Some of the below posted questions are simle to solve if you applied simple logic as you can find right answer by excluding wrong answers, even if you dont know the right answer, but if you know background information required to solve those questions. But some questions are quiet tricky and you are likely to be prey, by choosing the option, which were provided to entice you to click and trap.

I am not posting right answers of those questions right now, because it kills your creativity and your reading habit, just give a try. If any confusion you can ask me later.

  6. Which of the following statement regarding Hepatitis Virus culture is right?
    a. Both Hepatitis A virus and Hepatitis C Virus has not yet been grown to cell culture
    b. Hepatitis A virus can be grown to cell culture but Hepatitis C virus has not yet been grown in cell culture.
    c. Hepatitis C virus can be grown to cell culture but Hepatitis A virus has not yet been grown in cell culture.
    d. None of the Hepatitis virus (HAV, HBV, HCV, HDV, HGV) grows in cell culture.
  7. Which of the following statement(s) regarding laboratory diagnosis of Hepatitis virus is/are misleading?
    a. Recombinant Immunoblot Assay (RIBA) is one of the confirmatory test used to diagnose HCV infection
    b. The most important laboratory test for the detection of early HBV infection is the immunoassay for HBsAg
    c. The detection of IgG antibody in patients serum is the most important test for presumptive diagnosis of HAV infection
    d. The diagnosis of HDV Infection in the laboratory can be made by detecting delta antigen.


  1. I am not sure about all answers, but i tried to reach without any assistance (like a guess)
    1- retrovirus
    2- hepatitis A
    3- hepatitis D
