Anemia: Your CBC results suggest that you may have anemia. There are many different types of anemia and most commonly are related to iron deficiency, or a vitamin deficiency such as B9 or B12. How is your overall health? Do you maintain a healthy diet with adequate fruits and vegetables? The increased RDW reflects cells of different sizes. The low MCHC suggests not enough iron content in the blood cells.

You are NORMAL :): If your blood tests are all normal, specifically CBC test, except for mild abnormality in MCHC and RDW, then you have NO medical conditions and you are NORMAL. Why were MCHC and RDW slightly abnormal? Most likely reason is lab error, which is very common and cannot be avoided. I strongly suspect that if you get a repeat CBC test done, your MCHC and RDW will be normal, like the rest of your tests.
