extremely anemic?

Hi, welcome to the ehealth forum and I am glad to help you.
Generally, classification of anemia is based on the MCV, or the volume of individual red blood cells. If the MCV is low (less than 80), as in your case, the anemia is categorized as microcytic anemia.
The treatment of the anemia varies greatly. First, the underlying cause of the anemia should be identified and corrected. You should perform Peripheral Blood film (PBF) test to identify the type of anemia. For low iron anemia, treatment consists of iron supplementation in form of syrup or pills. In severe anemia, blood transfusions may be necessary. When the cause is not obvious, other tests such as ESR, ferritin, serum iron, transferrin, RBC folate level, serum vitamin B12, hemoglobin electrophoresis etc. are required.
So you must consult your hematologist for the proper diagnosis and further treatment as the same cannot be made online.
Hope this helps. Take care.
