I think the medical folks feel that it is just a bit early in the research cycle for this to become a general recommendation for physicians. I asked my MD about it, and he said that since he already had me on statins for cholesterol, that there was no real need to make the measurement (evidently statins ALSO affect the C-reactive protein in a positive way).
Since my dad had a heart attack at about the age I am now, you can bet I follow this stuff.
