There are several abnormalities in the blood film and you must ensure this is followed up.
1. Microcytic hypochromic morphology - means small cells with less colour and is usually due to iron deficiency
2. Polikilocytes - means abnormal shape and can be due to Vit B12 or folate deficiency
3. Target cells - are also abnormal; the red blood cells look like a shooting target with a bull's eye and can be seen in jaundice.
Hence, the follow up tests are iron levels, TIBC, transferrin
to exclude thalassemia
like disorders; B12 and folate levels; TTG-IgA to exclude coeliac disease where you get both iron and Vit B12/folate deficiency; liver function tests to know your bilirubin levels.
Please ensure this blood film result is followed up.
