The CBC is typically part of your regular checkup. "I also order a complete blood count for patients who are weak or tired; have swelling, bruising or bleeding; or who may have an infection,” Dr. Allan. explains. "This test also can help me check how a patient’s body is responding to medication.”

What if your test results are abnormal? Don't worry. They don't necessarily mean you’re sick.

Diet, menstrual cycle, medication and other factors can affect your scores. Talk to your doctor about your CBC results. He or she will explain any areas of concern and help you determine next steps.
