what is normal range for blood test wbc?
Some people naturally have a normal high or low number of WBCs. An increased number of WBCs can be due to a blood cancer, such as leukemia or lymphoma. The normal number of WBCs in the blood is 4,500 to 11,000 white blood cells per microliter (mcL). Normal value ranges may vary slightly among different labs. Some labs use different measurements or may test different specimens. Talk to your doctor about your test results.
