Lymphocytes is high (52%) and %immature granulocytes is low (38%) but rest of cbc is normal - should i be concerned? i am 65 y/o female.

Possibly but: but only if this is a persistent finding since the profile is also compatible with a current viral infection. I would repeat the test in a month. If the finding is similar , then you need to talk to your doctor re. whether a hematology consult is needed. It would have been more informative if you had given us the actual WBC count instead of just a %.
