Here is a different question. Is there a definitive test for endocarditis while it is developing? If you have been feeling unwell with symptoms of a cold that has lingered too long, with or without a fever, could you do a blood test and determine endocarditis? I ask because I've had so much dental work in the last 2 months and have some bleeding in gum, and now I have a cold (cough, headache but no fever) for a week. Having heard all stories, I always worry about endocarditis, but I am sure if I go to my PCP and ask for a test she will laugh it off. When I was first diagnosed, they asked me about having a high fever in the last few years, and then I talked about it with the cardio and she said endocarditis is associated with a high fever and is not like a common cold. However, I hear from people who have had it that they felt unwell for a while without a fever. It's so scary, now everytime I have a cold I get nervous.
They do blood cultures
