I just got my CRP test results. Quick back story: When my doctor found out I was taking 10,000 IU of D3 a day, she had several highly agitated cows. So she ordered up a Vitamin D test, plus a C Reactive Protein (CRP) High-Sensitivity test, because I also told her about my joint pain decreasing when I started ZC eating.
The D levels are fine, of course, although she thinks they're too high and wants me to cut back to 2,000 IU/day. I'm not going to do that. My number is 78 ng/mL, and optimal, according to them, is 35-100. She said mine were on the "high end of normal" and that "could be bad." Alrighty, then.
So the real news, though, is the CRP level. 0-3 is the reference range, and mine is 14.6.
It could be a false positive. They're common, or so a quick scan of the literature seems to show. Or infection, or heart disease, or cancer, but I have no symptoms and no lab work that even remotely points in any of those other directions. I do, however, have a history of joint pain and stiffness, elevated ANA (a marker for autoimmune disorders), and show a high Rheumatoid factor in blood work from when I visited the rheumatologist several years ago.
Of course she wants me to change my diet to include healthywholegrains and then get re-tested. That isn't going to happen; I have no interest in becoming fat and achy again just to prove she's wrong about grains (I mean geez, tons of research on diet and inflammation points to gluten as the likeliest culprit; what on earth makes her think a whole wheat sandwich is going to help?)
It's true that I've had some returning joint pain recently, but it seemed to me to be related to my new standing desk, and increased physical activity. Otherwise, I feel fantastic.
(I'm ZC, which is about as LC as it's possible to get, with plenty of pastured eggs and fatty coldwater fish, if that helps.)
So my questions are: Has anyone else here ever seen CRP levels like this? Should I worry? And:does anyone know of any paleo-compliant interventions that might help bring inflammation down?
UPDATE: After a sleepless night arguing with invisible doctors in my head, lol, I called my rheumatologist's office the next day and asked for the test results from my visit years ago. First of all, I was shocked to find out that I went to see him in October 2001! I didn't realize it was that long ago. That was many years before I knew anything about a low-carb diet.
Secondly, here are the blood panel results from that long-ago visit: ANA: positive. SED rate: 33 (ref range is 0-20). RA factor: 61. So all three were positive. This was also surprising to me; I'd vaguely recalled that some of the tests were positive, but certainly didn't know the numbers were so definitive.
This comes close to sealing the deal for me. I've got RA, or some related AI disease(s), and I'm having a flare. I will get my bloodwork re-done, hopefully by my new doctor (I have an appt July 7 with -- get this -- Dr. House), and meanwhile, I'm going to get on with my life and calm down a bit. I'll probably update again after the next round of labs.
