Iron Stain

An iron stain test is usually advised by a doctor when anemia remains unexplained or routine iron tests are inconclusive. It is recommended when sideroblastic anemia, myelodysplastic syndrome (MDS), hemochromatosis, iron overload, or intravascular hemolysis is suspected. It is often performed during a bone marrow or liver biopsy.

Preparation for an iron stain test depends on the sample type. For a bone marrow or liver biopsy, inform your doctor about blood thinners, allergies, bleeding disorders, or pregnancy, and you may need to fast if sedation is planned. For a urine sample, collect a clean first-morning specimen. Follow your doctor's instructions.

Fasting is usually not required for an iron stain test on urine or blood samples. However, if the test is done on a bone marrow or liver biopsy under sedation, you may need to fast for 4–6 hours beforehand. Always follow your doctor's or hospital's specific instructions.
