Overview
Anemia testing helps doctors find out if you have too few red blood cells or if your blood doesn’t carry enough oxygen. It usually starts with a complete blood count (CBC) and may include iron and vitamin tests. These results help diagnose the type and cause of anemia.
Candidates for anemia testing
You may need anemia testing if you:
- Feel weak, dizzy, or out of breath
- Have heavy menstrual bleeding or chronic illness
- Are pregnant or have poor nutrition
- Are being treated for anemia and need follow-up
- Are over age 65, when anemia is more common
Preparation for anemia testing
Most of the time, no special prep is needed. If other blood tests are ordered at the same time, your doctor might ask you to fast.
Risks for anemia testing
This test is very safe. You might feel a little soreness or see bruising at the needle site, but serious problems are rare.
Recovery from anemia testing
There’s no downtime. After your blood is drawn, you can return to your usual activities.
