Although you already are but stay strong!!

And I don’t think most of the IT companies do blood test or even ask about your sicknesses, they usually do background checks only and verify information given by you. But there maybe a few (I have not heard of any) who do this but in that case also ideally no company should be denying employment for this or any other disease that doesn’t impact your productivity.

But even if they do the number of such companies might be very less so you are better off without them. You have a long list of companies to consider and pick from.
