[New tests for laboratory diagnosis of spherocytosis]

The authors evaluated advantages of the glycerol lysis test (AGLT) and its modification the "pink" test in the laboratory diagnosis of hereditary spherocytosis (HS). Both tests were positive in all examined subjects with HS and in some patients with autoimmune haemolytic anaemia (AIHA) and were negative in controls and some other haemolytic diseases. As these tests are easy to perform and quick, they can be recommended as a supplementary or screening examination in hereditary spherocytosis. The "pink" test has, as compared with the ALGT test, the advantage that it is simpler.
