I got a full cbc done, was told everything was normal range, doctor wasn't concerned. when i looked at it though my monocyte count was 7.6% (range states normal is 0-7.3%) should i get a second opinion or be concerned?

Likely normal: All labs should be evaluated in proper clinical context. Your CBC was likely normal as the ranges provided for relative values are not usually used in decisions, but rather absolute values that in your case were likely normal as not being flagged as abnormal. Always talk to your doc and ask your questions.

Not meaningful: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Talk to the doctor who ordered the tests. Having said that, the difference between 7.6 and 7.3 is not clinically meaningful. Wish you good health!
