how soon after exposure to hepatitis i can also transmit the infection to a healthy person?

hello,
how soon after exposure i can also transmit the infection to a healthy person?
(question is for hep. B and hep. C)

i also have another question.
if i'm testing myself (for hep B and hep C) after 3 months from exposure and the results are negative than should i repeat the tests at 6 months? what are the chances to become positive from 3 months to 6 months?

and the last question...
if i'm testing myself (for B and C) after 6 months from exposure and the results are negative than is it a safe result?
afaik if i want to donate blood, the blood is accepted only after 1 year from exposure with negative results.

thank you for your answers

If you test negative at 6 months, you most likely don't have hep B or C. Remember that HCV is blood-borne and not as easy to contract as B. Both B and C are sometimes kicked out of your system by your system This happened for me with hep B, but not C, though I always test positive for hep B Instead of self-testing, I recommend that you go to your doctor for testing and results. Now I have blood testing regularly, post-transplant.
