It used to be the main parameter to measure when evaluating inflammation and infection, but nowadays other parameters are preferred, like [[CRP]] and [[leukocyte]] | It used to be the main parameter to measure when evaluating inflammation and infection, but nowadays other parameters are preferred, like [[CRP]] and [[leukocyte count]]. However, there are still some scenarios where the ESR is useful to measure. | ||
