title: Comparison of cultured human mononuclear cells, Limulus amebocyte lysate and rabbits in the detection of pyrogens.
abstract: Isolated human mononuclear cells exposed to either lipopolysaccharide or Staphylococcus aureus secreted interleukin-1 like material. The secretion was concentration dependent. The minimal detectable level in the test solution of lipopolysaccharide and Staphylococcus aureus was 200 pg/ml and 10(5) cells/ml respectively. The sensitivity and specificity of the Limulus Amebocyte Lysate test, the rabbit pyrogen test and the monocyte test are compared. The monocyte test is proposed as an alternative in-vitro test to the rabbit pyrogen test.
