Interpretation

Diagnosis of central nervous system infections can be accomplished by demonstrating the presence of intrathecally-produced specific antibody. Interpreting results may be complicated by low antibody levels found in CSF, passive transfer of antibody from blood and contamination via bloody taps.

Interpretive criteria:

IgG:

<0.90 Antibody not detected

0.9-1.09 Equivocal

≥1.10 Antibody detected

IgM:

<0.80 Antibody not detected
