Testing/Monitoring

  • What is a normal blood count and what do blood test abbreviations mean?

    Physicians use a blood test known as a Complete Blood Count, or CBC, to understand a patient's overall health and the health of blood cells. The test results show the counts of all types of blood cells, as well as how those cells are differentiated. The following table will help you sort through the differing counts and understand the meaning of the abbreviations.
