Clinical relevance

The haemoglobin molecule is responsible for transporting oxygen inside of the human organism, and consists of four globin polypeptide chains and one haem molecule. In humans, the globin polypeptide chains are further subdivided in α, β, γ and δ chains. Human haemoglobin usually consists of two α chains and two additional globin chains (β, γ or δ). In adults, the major component of haemoglobin is HbA (ααββ). Its glycated forms are referred to as HbA1a, HbA1b and HbA1c. HbA2 consists of two α chains and two δ chains. Foetal haemoglobin (HbF) consists of two α chains and two β chains.

Genetic disorders of haemoglobin production are called thalassaemias – they most commonly affect the β chain. This leads to β-thalassaemia. It is especially common in populations in the Mediterranean region, the Middle East and East Asia, but it also occurs in Middle Europe and North America as a result of demographic change.


Product advantages

  • Measurement of all key haemoglobin variants in just 9 minutes
  • Clear identifiable peaks and reliable values


By making use of the high separating capacities of the analytical column, the Chromsystems kit for the analysis of haemoglobin variants can determine the most common variants HbA1c, HbA2, HbC, HbD, HbE, HbF and HbS within 9 minutes. A column material specially designed for this specific separation process also allows a stable separation of HbA2 from HbD and HbE even with aged columns. This helps to eliminate false quantifications and qualifications.
