Your units and reference range are a bit different than my last test. I'd assume a 1.0 and below is considered normal, you are 1.7, so you're slightly above normal. I'd say you're a little high but that's nothing at all to be worried about or loose any sleep over. At worst, you have very, very mild inflammation but nothing major. I've been told CRP is notoriously fickle, you could have a test today and easily score a 1.0.
How are your symptoms?
My last C Reactive Protein from a few weeks back is this:
C Reactive Protein____<7.0_____<10.0 mg/
In my test 10 and below is normal, and I have a 7.

My reviews on Yelp and Trip Adviser will be terrible: @$10,000 a night with uncomfortable beds and awful food, but at least the drugs are good at this hospital.
