<s>[INST] I was on the mobile web on my cell phone. A lady asked about iron deficency. Her number was 9 and dropping. The advice was to have her dr check for a disease first before doing other tests. It was from your site. I couldn't read the name of the disease. Can you tell me what it is? [/INST] Hi,Thanks for asking the query.In iron deficiency anemia, the first is usually confirmation through a hemogram. The red cell indices are usually reduced. And in childrens, thalassemia needs to be ruled out as one of the cause.For confirmation of iron deficiency anemia, serum ferritin, total iron binding capacity needs to evaluated.I think, if it present for along time, it should be Thalassemia.Any further queries, happy to help again. </s>
