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 134.9 IV or less: Negative - No significant level of detectable varicella-zoster IgG antibody.
135.0-164.9 IV: Equivocal - Repeat testing in 10-14 days may be helpful.
165.0 IV or greater: 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, IgM by ELISA 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. IgM antibody to HSV detected, which may indicate a 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 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.
