﻿ When u get general blood work done do they test for
diseases?-ukcoalition.org *Home>>>HIV Test   I've had loads of
blood tests done due to a reoccurring sickness (tonsilitis). I
ended up needing surgery and they did a blood test before the
surgery. I've also given blood many times and they obviously
test the blood prior to giving it to someone who needs it.  What
exactly do they test for during those blood tests? If you have
hiv, stds, lupis, leukemia, or cancer unknowingly will these
show up on the blood tests?   They only check for those things
if you ask them to...in your case, they were looking for things
related to your tonsilitis...not STDs and things like that  When
you donate blood, they make you fill out a sheet with possible
illnesses you could have. And even if you say you dont have
them, they still test for all of them and if you're found to be
