One cause of an elevated CRP is an ongoing, chronic inflammatory condition. If it is falling, thats obviously the irection to go in. Anything under 10 would be good :)
Platelet count is essentially high normal. (NR 150-400 ish)Would not be unexpected to see a slightly elevated platelet count in a chronic inflammatory condition.
Hb is only slightly below the normal range for a female (NR115-160 ish). Not sufficiently low to be automatically classed as anaemic, and unless you have any of the clinical symptoms associated with anaemia, no need for concern.
