Values for Healthy Children
Each laboratory and lab handbook has slightly different reference values for each blood cell, so your lab sheets may differ from the one that appears below. There is also variation in values for children of different ages. For instance, in newborn to 4-year-old children, granulocytes are lower and lymphocytes higher than the numbers listed below. Geographic location affects reference ranges as well. The following table lists blood count values for healthy children:
Blood Count Type |

| Platelets | 160,000-500,000 mm3 | |
| White blood count | 5,000-10,000 mm3 or 5-10 K/ul | |
