Question: hi,
have been worried about possible hepatitis exposure 30 days ago..

1. how long does vacine for hep a and b last?
2. just had a test done by a dr to measure my liver. she banged on my ribs and tried to measure it and said was normal size. she did not palpate it...dont you need to palpate? how hard is it to measure enlarged liver on physical exam? would ultrasound be better? is that conclusive?
3. they are doing hep a antibody, hep b and c pcr is 30 days post exposure..will these tests be conclusive?

Thanks for posting your query.
I am Dr.Ratnakar Kini and I am pleased to answer your query.

1. If you complete the course of vaccination for Hep A and Hep B, the immunity will last life long.

2. Palpation and ultrasound scan would show whether the liver is enlarged. Ultrasound will show other features like if there is fatty deposition or any space occupying lesion.

3. Hep A antibody, Hep B Anti HB IgM and Hep C RNA will be positive in 30 days post exposure.

I hope that answers your question.
