Haptoglobin

Description: 
The measurement of haptoglobin is useful in the detection and evaluation of haemolytic anemia. It may also be helpful in distinguishing anemia due to other causes.
Clinical details: 
Haptogloblin is a complex group of allo-typically related glycoproteins. Three common phenotypes have been described. The main function of the haptoglobulins is conservation of iron by the binding of haemoglobin liberated on haemolysis. Reduced concentrations are seen in any clinical situations where there is intravascular haemolysis. Haptoglobin is an acute phase protein and concentrations are increased in any inflammatory condition, following trauma and neoplasia.
