Interpretive Data




Component
Interpretation
Measles (Rubeola) Antibody, IgG, CSF 13.4 AU/mL or less:  Negative. No significant level of IgG antibody to measles (rubeola) virus detected.
13.5-16.4 AU/mL:  Equivocal. Repeat testing in 10-14 days may be helpful.
16.5 AU/mL or greater:  Positive. IgG antibody to measles (rubeola) detected, which may indicate a current or past measles (rubeola) infection.
Measles (Rubeola) Antibody, IgM, CSF 0.79 AU or less:  Negative. No significant level of IgM antibodies to measles (rubeola) virus detected.
0.80-1.20 AU:  Equivocal. Repeat testing in 10-14 days may be helpful.
1.21 AU or greater:  Positive. IgM antibodies to measles (rubeola) virus detected. Suggestive of current or recent infection or immunization. However, low levels of IgM antibodies may occasionally persist for more than 12 months post infection or immunization.
Mumps Virus Antibody IgG, CSF 8.9 AU/mL or less:  Negative. No significant level of detectable IgG mumps virus antibody.
9.0-10.9 AU/mL:  Equivocal. Repeat testing in 10-14 days may be helpful.
11.0 AU/mL or greater:  Positive. IgG antibody to mumps virus detected, which may indicate a current or past mumps virus infection.
Mumps Virus Antibody IgM, CSF 0.79 IV or less:  Negative. No significant level of detectable IgM antibody to mumps virus.
0.80-1.20 IV:  Equivocal. Borderline levels of IgM antibody to mumps virus. Repeat testing in 10-14 days may be helpful.
1.21 IV or greater:  Positive. Presence of IgM antibody to mumps virus detected, which may indicate a current or recent infection. However, low levels of IgM antibody may occasionally persist for more than 12 months post infection or immunization.
Varicella-Zoster Virus Antibody, IgG, CSF <1.0 S/CO: Negative. No significant level of IgG antibody to varicella-zoster virus detected.
>=1.0 S/CO: Positive. IgG antibody to varicella-zoster virus detected, which may indicate a current or past varicella-zoster infection.
Varicella-Zoster Virus Antibody, IgM by ELISA (CSF) 0.90 ISR or less:  Negative. No significant level of IgM antibody to varicella-zoster virus detected.
0.91-1.09 ISR:  Equivocal. Repeat testing in 10-14 days may be helpful.
1.10 ISR or greater:  Positive. Significant level of IgM antibody to varicella-zoster virus detected, which may indicate current or recent infection. However, low levels of IgM antibodies may occasionally persist for more than 12 months post infection.
Herpes Simplex Virus Type 1 and/or 2 Antibodies, IgG, CSF 0.89 IV or less:  Negative. No significant level of detectable HSV IgG antibody.
0.90-1.09 IV:  Equivocal. Questionable presence of IgG antibodies. Repeat testing in 10-14 days may be helpful.
1.10 IV or greater:  Positive. IgG antibody to HSV detected which may indicate a current or past HSV infection.
West Nile Virus Antibody, IgG by ELISA, CSF 1.29 IV or less:  Negative. No significant level of West Nile virus IgG antibody detected.
1.30-1.49 IV:  Equivocal. Questionable presence of West Nile virus IgG antibody detected. Repeat testing in 10-14 days may be helpful.
1.50 IV or greater:  Positive. Presence of IgG antibody to West Nile virus detected, suggestive of current or past infection.
West Nile Virus Antibody, IgM by ELISA, CSF 0.89 IV or less:  Negative. No significant level of West Nile virus IgM antibody detected.
0.90-1.10 IV:  Equivocal. Questionable presence of West Nile virus IgM antibody detected. Repeat testing in 10-14 days may be helpful.
