Anaemia

Question 1

What is anaemia?

Answer 1

• Reduction in the amount of haemoglobin in a given volume of blood below what would be expected in comparison with a healthy subject of the same age and gender
• Hb is reduced
• RBC and Hct/PCV are usually also reduced

NOTE: occasionally it results from an increase in the volume of plasma rather than a decrease in the amount of haemoglobin

Question 2

In a healthy person, anaemia resulting from an increase in plasma volume cannot persist because…?

Answer 2

The excess fluid in the circulation is excreted
For practical purposes, anaemia can therefore be regarded as resulting from a decrease of the absolute amount of haemoglobin in the circulation
