What this test is

Anemia testing is a group of blood tests that measure red blood cells, hemoglobin, and related markers. It can include a complete blood count and tests for iron, vitamin B12, or folate levels. Together, these tests help classify the type of anemia and guide further evaluation.

What it measures

  • Hemoglobin — the oxygen-carrying protein in red blood cells
  • Hematocrit — the proportion of blood made up of red blood cells
  • Red blood cell count — the number of red blood cells in a volume of blood
  • Mean corpuscular volume — the average size of red blood cells
  • Ferritin — a protein that reflects stored iron in the body
  • Vitamin B12 — a vitamin needed for healthy red blood cell production
  • Folate — a vitamin that helps make red blood cells

What the test involves

A healthcare professional collects a blood sample, usually from a vein in your arm, using a standard blood draw. The sample is then sent to a laboratory for analysis.

Why it is often ordered

A clinician may order anemia testing if you have symptoms such as persistent fatigue, pale skin, or shortness of breath. It is also used to monitor ongoing conditions or treatments that can affect red blood cells.

Preparation

Preparation depends on which specific anemia tests are ordered. Follow the instructions provided by the collection lab, as some tests may require fasting or timing around meals or supplements.

How results are reported

Results are typically reported as numbers for each marker, often with a reference range from the performing laboratory. Reference ranges can vary between laboratories, so your results should be interpreted in the context of the lab that performed the test.

Before you go

  • Whether any fasting or timing restrictions apply to your specific tests
  • How and when you will receive your results
  • Whether the lab requires a doctor's order or referral
