CBC a bit off

Female (22 years old) got my full CBC test (annual checkup) everything is within normal range except: erythrocytes are very slightly elevated (just by half a point than normal range) MCV, MCH and MCHC are slightly lower than normal range and MPV is 11.8(normal range is 9 - 10.4) What this could possibly mean? and should I be worried about high MPV?
