What is a complete blood count (CBC)?
The complete blood count (CBC) is done to determine the levels of various types of blood cells, including red blood cells (RBCs), white blood cells (WBCs), and platelets (Plt). Additionally, a CBC also includes a hemoglobin value and a hematocrit. This test helps determines the degree to which myeloma is interfering with the blood cell production. Low blood count levels may signal anemia, or increased risk of infection.
