Which CSF findings is most consistent with viral meningitis?


Which CSF findings is most consistent with viral meningitis?

The CSF protein was 0.85 g/L and CSF glucose 3.5 mmol/L. This shift from predominantly neutrophilic to lymphocytic pleocytosis was most consistent with viral meningitis, and the child was discharged home.

What are the CSF findings in viral meningitis?

CSF: cerebrospinal fluid; WBC: white blood cell; RBC: red blood cell; ↑: elevated; ↓: decreased; NL: normal; SL: slightly. * In most cases of viral meningitis, the CSF WBC is within the range of 10 to 500 cells/microL, though higher values can be seen with some viruses.

What labs are elevated with viral meningitis?

The serum amylase level may be elevated in cases of viral meningitis that are caused by mumps, even in the absence of parotitis. Reports have shown high C-reactive protein (CRP) levels in the serum of children with bacterial meningitis whose CSF Gram stain findings were negative for bacteria.

Is CSF protein high in viral meningitis?

In most cases of viral meningitis the protein concentration is < 1.0 g/lL. In contrast, acute bacterial meningitis is usually associated with a CSF protein concentration between 1.0 and 5.0 g/L. CSF protein is almost always high in tuberculous meningitis.

Can CSF be normal in viral meningitis?

Normal cerebrospinal fluid (CSF) findings do not exclude viral meningitis. In the appropriate clinical setting, PCR testing of CSF should be performed even on samples with normal cell counts.

What labs are ordered for meningitis?

Which lab tests should be ordered in suspected meningitis?

  • Blood, nasopharynx, respiratory secretion, urine or skin lesion cultures or antigen/polymerase chain reaction (PCR) detection assays.
  • Syphilis testing.
  • Serum procalcitonin testing.
  • Lumbar puncture and CSF analysis.
  • Neuroimaging (CT of the head or MRI of the brain)

What CBC results would be consistent with meningitis?

Analysis of the spinal fluid shows the presence of gram negative, diplococcoid bacteria (Gram stain) and a moderate to high elevation of the number and type of cells in the spinal fluid clearly indicate a bacterial meningitis. Consistent with the findings are decreased glucose and elevated protein levels in the fluid.

Is WBC elevated with viral meningitis?

Acute viral meningitis is characterized by elevated white blood cell count (WBC) in the cerebrospinal fluid (CSF) with lymphocytic predominance; it is usually < 1000 cells/µL. Proteins in the CSF are usually only slightly elevated (usually < 250 mg/dL), while glucose is normal.

How do you diagnose viral or bacterial meningitis?

To determine whether a person is suffering from viral or bacterial meningitis, doctors will have to perform a lumbar puncture. This involves collecting a sample of the cerebrospinal fluid (CSF) that surrounds the brain and spinal cord to find out what is causing the meningitis.

Can CBC detect viral meningitis?

A complete blood count (CBC) or total protein count check for heightened levels of certain cells and proteins that can suggest a meningitis infection. A procalcitonin blood test can also help your doctor tell if an infection is more likely caused by either bacteria or a virus.
