An anemia Profile is a group of blood tests that helps find the cause of low haemoglobin and tiredness. Anemia happens when your red blood cells cannot carry enough oxygen, leading to weakness, breathlessness, palpitations, headache and poor concentration. Common reasons include blood loss (heavy periods, bleeding from the stomach or intestines), poor production of red blood cells, or accelerated destruction of red blood cells. This profile mainly checks whether your anemia is due to iron deficiency, which is very common in India, and guides your doctor on iron supplements, dietary changes, further tests such as serum ferritin, and a search for hidden blood loss.
