Talk to your doctor if you think you may have anemia. The only way to know if you have anemia is to have a blood test. When you have kidney disease, your doctor will want you to have blood tests often. These tests are used to check not only your kidney function, but also for signs of any other problems, such as the number of red blood cells and how much iron you have in your body.
The test for anemia is a simple blood test to check for the amount of hemoglobin in your blood. Hemoglobin is a part of your red blood cells. Figuring out the amount of hemoglobin you have in your blood can tell your doctor how many red blood cells you have.
Your doctor may also ask you if you’ve noticed any symptoms, such as changes in skin color or feeling unusually tired.
