An evaluation of the acidified glycerol lysis test

The acidified glycerol lysis test (AGLT), as a screening procedure for spherocytosis, has been assessed for sensitivity and specificity. AGLT identified 24 of 26 subjects with hereditary spherocytosis and produced 19 abnormal AGLTs out of a total of 52 normal blood donors. The claims for the test as being both 100% sensitive and specific could not be confirmed.
