<prompt> Answer this question truthfullyWhat are the laboratory test results for bacterial meningitis?  <response>: <reason> Labortary tests which may help identify the bacterial meningitis include non specific tests and specific diagnostic tests.Non specific tests include blood tests such as complete blood count, liver function tests, renal function tests, biochemistry, and coagulation profile. Laboratory findings Test Findings Complete blood count Decreased hemoglobin Decreased hematocrit Elevated CRP White blood cell count Elevated or decreased leukocyte countsevere infection with a left shift To detect meningococcal septicemia, routine assessment of the neutrophil counts must be considered, as follows: Absolute Neutrophil Count ANC: 1000mm or 10,000mm Immature Neutrophil Count INC: 500mm Immature-to-Total Neutrophil Ratio ITR: 0.20 Biochemistry Hypoglycemia Elevated creatinine Elevated ALT, AST Possible hyponatremia Acidosis: High lactate; Low bicarbonate shock Coagulation Thrombocytopenia -poor prognosis Increased D-Dimers, Increased PTAPTT- DIC Blood culture Positive in 50 to 90 percent of patients Two sets of blood cultures needed before antimicrobialsSpecific diagnostic tests include lumbar puncture with CSF examination and CSF culture. CSF examination findings in bacterial meningitis are as follows:CSF gram stain findings include the following: CSF Gram Stain Finding Causative Organism Culture medium Growth on culture medium Gram positive diplococcus Streptococcus Pneumonia Blood agar plate Small, grey, moist sometimes mucoidal, watery colonies with green zone of allpha hemolysis Gram negative diplococcus Neisseria Meningitides Blood agar plate and chocolate agar plate Round, smooth, moist, glistening, and convex Gram positive coccobacillus Listeria Monocytogenes Brain heart infusion Isolated small 1mm colonies creamy white in colour and dome shaped Small pleomorphic gram - negative coccobacilli Haemophilus Influenzae Chocolate agar plate enriched with NAD and hematin X Large, colorless-to-grey, opaque colonies
