What Are the Normal Range Lab Values for Blood Tests?

In a complete blood count test, the normal range for red blood cells is 4.32 to 5.72 trillion cells per liter for men and 3.90 to 5.03 trillion cells per liter for women. The normal range for hemoglobin is 13.5 to 17.5 grams per deciliter for men and 12.0 to 15.5 grams per deciliter for women. The normal range for hematocrit is 38.8 to 50.0 percent for men and 34.9 to 44.5 percent for women, according to Mayo Clinic.

For both men and women, the normal range for white blood cells is 3.5 to 10.5 billion cells per liter, and the normal range for platelets is 150 to 450 billion platelets per liter, according to Mayo Clinic.

Health care providers use the complete blood count test to discover the state of blood cells and platelets in their patients’ blood and diagnose some diseases, such as anemia, leukemia and infection. When values fall outside of the normal range, this could indicate an underlying condition or pathology, according to Mayo Clinic. Different laboratories have different ranges for normal complete blood count values. When a lab result is outside of the normal range, it doesn’t always indicate poor health or the presence of disease, according to WebMD.
