What is Haemoglobin?

Haemoglobin is a type of globular protein present in red blood cells (RBCs), which transports oxygen in our body through blood. It is a tetrameric protein and contains the heme prosthetic group attached to each subunit.

What are the 3 types of haemoglobin?

There are several different types of haemoglobin present in the population due to mutation in genes. Not all mutations lead to diseases. The three main types of haemoglobin are:

• Haemoglobin A (α2β2) – It accounts for 95-98% of haemoglobin in adults. It is composed of two alpha and two beta polypeptide chains.
• Haemoglobin A2 (α2δ2) – It accounts for 2-3% of haemoglobin present in adults. It is composed of two alpha and two delta polypeptide chains.
• Haemoglobin F (α2γ2) – It is known as fetal haemoglobin. 2-3% of haemoglobin F is present in adults. It is composed of two alpha and two gamma chains. Fetal haemoglobin has more affinity for oxygen compared to HbA.

What is the normal haemoglobin level?

• Children – 11-13 g/dl
• Adult male – 14-18 g/dl
• Adult female – 12-16 g/dl
• Old males – 12.4-14.9 g/dl
• Old females – 11.7-13.8 g/dl
