Question

In normal healthy individuals, the percentage of adult and fetal haemoglobin, the ratio of HbA: HbA${}_2$ : HbF is

• A. 96: 2: 2
• B. 45: 45: 10
• C. 50: 45: 5
• D. 80: 10: 10

Answer 1

The correct option is A 96: 2: 2

Normal hemoglobins in the red blood cell consist of hemoglobin A (HbA), fetal hemoglobin (HbF) and hemoglobin $A_2$ ($Hb{A}_2$).
The percentage of Hb A is around 97%, while that of Hb F is <2% and $Hb{A}_2$ is 2% -3%
Thus, the correct answer is option A.
