Interpretive Data
| Component |
Interpretation |
|---|---|
| Measles (Rubeola) Antibody, IgG | 13.4 AU/mL or less: Negative. No significant level of detectable measles (rubeola) IgG antibody. 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 exposure/immunization to measles (rubeola). |
| Measles (Rubeola) Antibody, IgM | 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 | 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 exposure/immunization to mumps virus. |
| Mumps Virus Antibody, IgM | 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 | <1.0 S/CO: Negative. No significant level of detectable varicella-zoster IgG antibody. >=1.0 S/CO: Positive. IgG antibody to varicella-zoster detected, which may indicate a current or past varicella-zoster infection. |
| Varicella-Zoster Virus Antibody, IgM | 0.90 ISR or less: Negative. No significant level of detectable varicella-zoster virus IgM antibody. 0.91-1.09 ISR: Equivocal. Repeat testing in 10-14 days may be helpful. 1.10 ISR or greater: Positive. Significant level of detectable varicella-zoster virus IgM antibody. Indicative of current or recent infection. However, low levels of IgM antibodies may occasionally persist for more than 12 months post infection or immunization. |
| Herpes Simplex Virus Type 1 and/or 2 Antibodies, IgG | 0.89 IV or less: Not Detected. 0.90-1.09 IV: Indeterminate. Repeat testing in 10-14 days may be helpful. 1.10 IV or greater: Detected. |
| West Nile Virus Antibody, IgG by ELISA, Serum | 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, Serum | 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. 1.11 IV or greater: Positive. Presence of IgM antibody to West Nile virus detected, suggestive of current or recent infection. |
