Interpretation
Absence of plasma haptoglobin may indicate intravascular hemolysis. However, congenital anhaptoglobinemia is common, particularly in African Americans. For this reason, it may be difficult or impossible to interpret a single measurement of plasma haptoglobin. If the assay value is low, the test should be repeated after 1 to 2 weeks following an acute episode of hemolysis. If all the plasma haptoglobin is removed following an episode of intravascular hemolysis and if hemolysis ceases, the haptoglobin concentration should return to normal in a week.
Low levels of plasma haptoglobin may indicate intravascular hemolysis.
