What does a complete blood count tell you?

Understanding the Complete Blood Count. Typically speaking, an RBC count is less useful on its own to diagnose a medical condition.

What does it mean when your red blood cell count is high?

Various types of red blood cell disorders can cause a red blood cell count to be low or high. Anemia often is what causes a low red blood cell count, and rare disorders like red or white cell cancers can cause a high red blood cell count. The red blood cell count normal ranges for adults are: Men: 4.5 to 5.9 x 106 per microliter of blood

This in turn causes more blood to flow through your heart in a single minute than typically does, known as increased cardiac output. The blood also carries less oxygen so your blood vessels dilate, further reducing resistance and increasing the speed of blood flow.
