I had a blood test i see mono% 9.5 high, eos% 9.3 high, mchc 32.3 low, rdw 11.4 low . what should i do. should i worry. thanks.

Stop worrying: As a pathologist / lab physician, i often wish we didn't even have to report percentages -- they mean nothing apart from absolute values, and even these fluctuate chaotically / meaninglessly. Reference ranges are set so that several % of healthies fall outside; low RDW never means anything and the MCHC looks fine to me. Go enjoy your healthy body ; pay attention to how you feel, not numbers.

High eos...: ...Usually raise suspicion of allergy or parasite infection; others are nonspecific. A better question would be , why was the test done in the first place?
