The normal ranges for hematocrit are dependent on age and, after adolescence, the sex of the individual. The normal ranges are: Newborns: 55%-68%. One (1) week of age: 47%-65%. One (1) month of age: 37%-49%. Three (3) months of age: 30%-36%. One (1) year of age: 29%-41%. Ten (10) years of age: 36%-40%.
The hematocrit measures the volume of red blood cells compared to the total blood volume (red blood cells and plasma). The normal hematocrit for men is 40 to 54%; for women it is 36 to 48%. This value can be determined directly by microhematocrit centrifugation or calculated indirectly.
