What does a very low level of CRP of 0.18 mean?

Can CRP as as low as 0.18 too much of a good thing? I mean, how low is too low?

I was at the doctor this week and I had a CRP test and the results were 2 (i have had flu/cold symptoms for a month). I told him that was a lot higher than my last test which was <1. He said anything under 10 is fine, it starts to become a problem when 50-100, and he had seen a client that week with 250+. He said that it is an incredibly inaccurate test, as anything can increase it, such as a scratch or graze etc.

Anyway, .18 is very, very low, indicating hardly any inflammation. IMO, you have happy insides.

C-Reactive Protein scores below 0.2 are excellent. I'm not sure what is considered unhealthy or risky. Lower levels indicate low inflammation, which is obviously a good thing.

This doesn't quite answer your question, but that looks pretty normal rather than low, based on Wolfram Alpha's parsing of the NHANES data:

The lower the better, the ideal being zero in the standard CRP test.

If you have a low CRP result (as you do), you can get a more accurate test (if required) with the hs-CRP (High-sensitivity C-reactive protein) test.

"There are two different tests for CRP. The standard test measures a much wider range of CRP levels but is less sensitive in the lower ranges. The hs-CRP test can more accurately detect lower concentrations of the protein (it is more sensitive), which makes it more useful than the CRP test in predicting a healthy person's risk for cardiovascular disease."

Edit: actually, it looks like the CRP test you had done was the hs-crp test. I just read some info that says the standard CRP test measures CRP in the range from 10 to 1000 mg/L & the hs-crp test measures CRP in the range from 0.5 to 10 mg/L. source.

Thanks for the links and responses. When I called in for my results, the nurse read it out to me as if something was wrong. When I asked her if that was bad, she said "I don't know - you better ask your doctor". Sheesh.
