This review indicated that good LAL tests in CSF have been noticed in 38 (a hundred%) of 38 culture-verified GNB meningitis scenarios [23]. CSF is ideal for the LAL test due to its somewhat very low written content of interfering substances derived from blood. In several subsequent studies, the LAL test was confirmed to be a sensitive, effective, and accurate diagnostic Software for detecting GNB meningitis.
