Schumm test

The Schumm test (shoom) is a blood test that uses spectroscopy to determine significant levels of methaemalbumin in the blood. A positive result could indicate intravascular hemolysis. The Schumm test was named for Otto Schumm, a German chemist who lived in the early 20th century.

A positive test result occurs when the haptoglobin binding capacity of the blood is saturated, leading the hemoglobin to bind to albumin instead. Further excess in hemoglobin will result in hemoglobinemia and hemoglobinuria. Hemosiderinuria will also result if there is chronic intravascular hemolysis.
