title: [Clinical value of endotoxin determination in infection. Comparison of the Limulus amebocyte lysate test with detection of bacterial pathogens].
abstract: To evaluate usefulness of Limulus amoebocyte lysate test and blood culture in the diagnosis of septicemia both tests were performed in 27 intensive care patients. Test results were compared with a clinical sepsis score. Ten (62%) out of 16 patients with clinical diagnosis of septicemia showed a positive endotoxin test and 11 (69%) a positive blood culture. In 14 patients (87%) either endotoxin test or blood culture revealed a positive result. Two out of 11 patients (20%) classified by the sepsis score as non-septic showed positive blood cultures as well as positive endotoxin tests. 4 patients with gram-positive bacteria in the blood cultures showed a positive endotoxin test. Due to lack of sensitivity and specificity the Limulus amoebocyte lysate test is of rather low value in the diagnosis of septicemia. Simultaneous performance of Limulus amoebocyte lysate test and blood culture is able to improve the sensitivity, which then over-rules the one obtained when only blood cultures are performed.
