What are normal blood lab results?


Quick Answer

A normal white blood cell count for men and women who are not pregnant falls between the range of 5,000 and 10,000 white blood cells per cubic millimeter, according to WebMD. A normal red blood cell count is 4.5 to 5.5 million cells per microliter in men and 4 to 5 million cells per microliter in women. Children should have between 3.8 and 6 million red blood cells per microliter, and newborns should have between 4.1 and 6.1 million.

Another common measure in a complete blood count is hemoglobin level, explains WebMD. The normal adult hemoglobin range is from 14 to 17.4 grams per deciliter in men and 12 to 16 grams per deciliter in women. Healthy children have hemoglobin levels ranging from about 9.5 to 20.5 grams per deciliter, and healthy newborns have between 14.5 and 24.5 grams of hemoglobin per deciliter.

When reviewing lab results, what qualifies as a normal range sometimes varies between lab facilities, notes WebMD. Most reports list the lab's normal range beside each measure. Labs may also differ in the units of measurement they use to report results. For example, a lab may report white blood cell count in cells per liter instead of per cubic millimeter. In this case, a healthy range is between about 5.0 x 10^9 and 10.0 x 10^9.
