Reference Values

REFERENCE RANGE:  < 1:1

           

INTERPRETIVE CRITERIA:

  < 1:1 Antibody Not Detected

  ≥ 1:1 Antibody Detected

           

Diagnosis of infections of the central nervous system is accomplished by demonstrating the presence of intra-thecally-produced specific antibody.  Interpretation of results may be complicated by low antibody levels found in CSF, passive transfer of antibody from blood, and contamin-ation via bloody taps.  The interpretation of CSF results must consider CSF-serum antibody ratios to the infectious agent.
