Wbc is normal (6.0), but mono% is too big (13,4%) while mono count is still upper normal (0.8). do i need to worry?

Not to worry: Please rest assured and do not worry. Unless you have symptoms fever, malaise and others, the normal WBC and normal absolute monocyte counts should be a good sign. Fluctuations in blood subset percentages are common and normal; it is a way to say our body is responding well, regardless of age, to any little or more potential infections, tissue cuts or injuries.

Stop worrying: Modestly elevated monocytes like that basically never mean anything if you feel okay.

Labs....: Hi L.M320, in terms of lab results, it is best to let the doctor that requested them interpret them for you. He will have a better understanding as to the context. Sometimes, an abnormal value is fine and sometimes a normal value is not fine. Understanding the background and context makes all the difference. You should make some time to communicate with your doctor. Hope that helps.
