This analyze indicated that favourable LAL tests in CSF were noticed in 38 (a hundred%) of 38 lifestyle-proven GNB meningitis situations [23]. CSF is perfect for the LAL test because of its comparatively very low content of interfering substances derived from blood. In a number of subsequent reports, the LAL test was demonstrated to generally be a sensitive, efficient, and correct diagnostic Instrument for detecting GNB meningitis.
