Iron Deficiency Anaemia

Low. Low MCV (microcytic anaemia) occurs because insufficient iron limits haemoglobin synthesis, reducing RBC size. ---

Also written as IDA.

In iron deficiency anaemia the soluble transferrin receptor is increased

Treatment at a glance

Ferrous sulfate 200 mg once to three times daily for about 3 months after the haemoglobin normalises

In iron deficiency anaemia the soluble transferrin receptor is increased (Internal Medicine End of Semester CAT (MBChB 4): haematology and renal, 30 MCQs )
A ferritin of 200 mcg/L is likely with iron deficiency anaemia (Internal Medicine End of Semester CAT (MBChB 4): haematology and renal, 30 MCQs )
The only true statement is that relative iron-deficiency anaemia is common (a cyanotic child should have a high haematocrit, so a normal level means anaemia). (Paediatrics Year 6 MBChB end of semester CAT: clinical case MCQs, 29 of 30 quest)
Regarding iron-deficiency anaemia in infancy, the following is true EXCEPT: (Paediatrics Year 6 MBChB end of semester CAT: clinical case MCQs, 29 of 30 quest)
Physical findings suggesting iron deficiency anaemia (4 marks) (Junior Clerkship in Internal Medicine (MBIM4100) main exam, Paper One: 31 Januar)
Probable diagnosis: microcytic anaemia, most likely iron deficiency anaemia (heavy menstrual bleeding, poor diet or worms). (Internal Medicine (MBIM 4100) special/supplementary exam, Paper Two: 14 August 2)

Answer: C. Low MCV (microcytic anaemia) occurs because insufficient iron limits haemoglobin synthesis, reducing RBC size. ---
