Unstable Hemoglobin, Blood

Method Description Describes how the test is performed and provides a method-specific reference

Unstable hemoglobins precipitate in dilute solutions of isopropanol. Washed erythrocytes are hemolyzed and cleared by centrifugation. Isopropanol is added. The hemolysate is incubated at 37 degrees C for 20 minutes and examined for turbidity. There is no turbidity with normal hemoglobins.(Schmidt RM: Laboratory diagnosis of hemoglobinopathies.
