Anemia
Anemia means the blood has a lower-than-expected amount of healthy red blood cells or hemoglobin.
Why is this important?
Understanding the purpose and limits of laboratory information can support a more informed conversation with a qualified healthcare professional.
How laboratory testing relates
A complete blood count and other tests may help a professional investigate the type and possible cause. Anemia has many causes and should not be assigned from one value alone.
Before testing
Preparation is test-specific. Follow the instructions given for the exact test and contact the laboratory if fasting, timing, medicines, or specimen collection is unclear. Do not stop medicines unless a qualified professional tells you to.
