Full Answer

The CBC, or complete blood count, measures the number of red blood cells, white blood cells and platelets in the blood. The test panel also measures a person's hemoglobin and hematocrit levels. Someone with HIV may have a higher-than-normal number of white blood cells. This is because white blood cells fight infections.

If the HIV ELISA test is positive, the patient has to have the HIV Western blot test to confirm the positive result.
