C Reactive Protein Blood Test?

I was ordered this test to see how high my levels are for possible Fibromyalgia.

I was reading online that it can be an indicator for future heart risks, like CAD, etc.

I was just wondering if anyone here knew how accurate that was?
and if they've ever been testing for CRP, when they've had heart problems.

I was told by my cardiologist that the only thing ive got against me at the time is pre-diabetes, and being obese. both of which im working on.

this is probably all my health anxiety getting the better of me.


thanks.
