Rapid detection of Gram-negative bacteriuria by Limulus amoebocyte lysate assay.
The Limulus amoebocyte lysate (LAL) test was evaluated for rapid detection of gram-negative bacteriuria in an adult patient population. Time to gelation of a standard LAL preparation was used as a measure of significant (greater than 10(5) bacteria per ml) gram-negative bacteriuria, and the results of 190 LAL assays were compared with quantitative urine cultures. Initially, 33 of 36 urine speci...
متن کاملChromogenic Limulus amoebocyte lysate assay for rapid detection of gram-negative bacteriuria.
A chromogenic Limulus amoebocyte lysate assay was evaluated as a rapid screening test for the detection of clinically significant gram-negative bacteriuria. The development of a distinctive yellow color after the addition of chromogenic substrate to the Limulus amoebocyte lysate-urine reaction mixture was used to measure greater than or equal to 10(5) gram-negative bacteria per ml. A total of 3...
متن کاملRapid detection of gram-negative bacterial peritonitis by the Limulus amoebocyte lysate assay.
The chromogenic Limulus amoebocyte lysate test effectively detected 66 (100%) culture-proven gram-negative peritonitis cases among 185 continuous ambulatory peritoneal dialysis patients with clinical evidence of infectious peritonitis.
متن کاملRapid detection of significant bacteriuria by use of an automated Limulus amoebocyte lysate assay.
Previous studies have demonstrated that significant gram-negative bacteriuria can be detected by using the Limulus amoebocyte lysate test. A series of 580 urine specimens were tested in parallel with the automated MS-2 (Abbott Laboratories) assay and with quantitative urine bacterial cultures. The overall ability of the MS-2 Limulus amoebocyte lysate test to correctly classify urine specimens a...
متن کاملDetection of endotoxin in the plasma of patients with gram-negative bacterial sepsis by the Limulus amoebocyte lysate assay.
A total of 120 Limulus amoebocyte lysate (LAL) determinations were made on plasma obtained from normal, healthy human blood donors. Results demonstrated a mean endotoxin level in blood of 0.02 to 1.57 pg/ml. The amount of Escherichia coli endotoxin added to human plasma samples can be quantitated by both nephelometry and turbidimetry. Endotoxin-spiked samples were shown to be significantly diff...
