What is a CBC Test?
The CBC test is a common blood test also known as a Complete Blood Count test, CBC panel test, and CBC with differential. Subcomponents include the WBC, RBC, Hemoglobin, Hematocrit, MCV, MCH, RDW, and Platelets.
Why is the WBC count in the CBC test important?
The WBC count measures the number of white blood cells and breaks down the different types of cells (neutrophils, lymphocytes, monocytes, eosinophils and basophils). Increased counts suggest infection or inflammation while decreased counts suggest a weakened immune system.
Why are the Hemoglobin, RBC count, and Hematocrit in the CBC test important?
The Hemoglobin, RBC and Hematocrit check your level of red blood cells. A deficiency of red blood cells, known as anemia, can impact the oxygen being delivered to your body.
Why is the Platelet count in the CBC test important?
Platelets are important for blood clotting. Too many platelets can cause excessive clotting while too few platelets can cause bleeding.
