If someone is found to have iron deficiency anaemia, what questions should be asked?
- Bleeding – menorrhagia
- Pregnancy
- Diet
- GI symptoms
- Possibly refer for GI investigations – especially if a man even with no symptoms to find out why iron is low as GI tract most common place
Describe the treatment for iron deficiency anaemia?

What investigations can be done to confirm diagnosis in normochromic normocytic anaemia?
- Bilirubin (indirect),, LDH
- Breakdown of red cells
- Reticulocyte count
- Bone marrow function
- Serum haptoglobin
- Breakdown of red cells
- DAGT (Coombs test)
- Working out why spherocytosis on film
- Tells us if patient has antibodies on surface of cell – could be autoantibody (against your own cells) or alloantibody (against red cells that are not yours)
What is DAGT?
Coombs test
- Tells us if patient has antibodies on surface of cell – could be autoantibody (against your own cells) or alloantibody (against red cells that are not yours)
What does a positive Coombs test mean?
If DAGT is positive:
- Autoimmune haemolysis
