The above labs were taken on the same day from a 72 yo M in the hospital.

True or false: The CRP is elevated, so the ESR must be as well.

a
True
b
False
There are occasional instances of discordance between CRP and ESR. For example, if the patient had DIC and low fibrinogen, the ESR might not be elevated.
