Doc says spleen isn't really enlarged at 13cm on CT- not concerned. WBC plateletsnml. Is it true this is high end of nml and could be normal for me?

Spleen. A 13cm spleen is borderline in size for splenomegaly. As long as you show no signs of any illness and your blood counts are normal, it may be appropriate to observe it. Speak with your doctor about what to do to follow it. Good luck. .
