This is pretty much a "well duh" response from me. I did warn you.
Jaundice means your LIVER isn't working.
If it isn't working, it isn't filtering out all the toxins your body normally produces.
Which means you could DIE. I'm surprised the moment you saw you had jaundice, you didn't get to a doctor or hospital right away.
The tests are to find out preciesly WHY your liver is not working.
Go get the tests done, so they can treat it, and so you don't DIE.
This might sound cold, Lady, but really, NOT going to see a doctor was perhaps the silliest idea ever, and downright DANGEROUS. :/
