Sle pt. sed rate >140 but crp normal. dr says i have pleuritis but sed has never been this high. trying to understand. ?

Unusual: A normal CRP suggests that there is no significant inflammation going on. The SED rate can be elevated when there is anemia or estrogen treatment even without inflammation. In general, I prefer CRP. As for pleuritis, it is a clinical diagnosis and not diagnosed by a lab test. There may be other explanations for this discrepancy but the above is what I can think of.
