What is the most common anaemia
Iron-Deficiency
How can aetiology of IDA be divided
- Insufficient intake
- Increase need
- Increase loss
What can lead to insufficient oral intake
Vegan
Eating Disorder
What are 3 causes of insufficient absorption
Whipple’s procedure
Coeliac disease

- Haematemesis
- Haematuria
- Trauma
What can cause occult blood loss

How will FBC present in IDA
- Low Hb
- Low MCV
- Low MCHC
- High RDW
How will iron studies present in IDA
- Low Ferritin
- Low transferrin saturation
- High TIBC
Explain TIBC in IDA
Low iron concentration means more free sites on transferrin to bind
What is the problem with using ferritin as a marker for anaemia
Ferritin is an acute phase protein and increases with inflammation

- Poikilocytosis
- Target cells
What is anisocytosis
cells unequal in size
What is poikilocytosis
cells unequal in shape
