Test Number Components Reference Interval
0050380Measles (Rubeola) Antibody, IgG 0.89 IV or less: Negative - No significant level of detectable measles (rubeola) IgG antibody.
0.90-1.09 IV: Equivocal - Repeat testing in 10-14 days may be helpful.
1.10 IV or greater: Positive - IgG antibody to measles (rubeola) detected, which may indicate a current or past exposure/immunization to measles (rubeola). Positive IgG antibody levels in the absence of current clinical symptoms may indicate immunity.
0099597Measles (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.
0050390Mumps Virus Antibody, IgG 0.89 IV or less: Negative - No significant level of detectable IgG mumps virus antibody.
0.90-1.09 IV: Equivocal - Repeat testing in 10-14 days may be helpful.
1.10 IV or greater: Positive - IgG antibody to mumps virus detected, which may indicate a current or past exposure/immunization to mumps virus. Positive IgG antibody levels in the absence of current clinical symptoms may indicate immunity.
0099589Mumps 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.
0050167Varicella-Zoster Virus Antibody, IgG 0.89 IV or less: Negative - No significant level of detectable varicella-zoster IgG antibody.
0.90-1.09 IV: Equivocal - Repeat testing in 10-14 days may be helpful.
1.10 IV or greater: Positive - IgG antibody to varicella-zoster detected, which may indicate a current or past varicella-zoster infection. Positive IgG antibody levels in the absence of current clinical symptoms may indicate immunity (98% correlation with IFA).
0099314Varicella-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.
0050641Herpes Simplex Virus Type 1 and/or 2 Antibodies, IgM by ELISA 0.89 IV or less: Negative - No significant level of detectable HSV IgM antibody.
0.90-1.09 IV: Equivocal - Questionable presence of IgM antibodies.  Repeat testing in 10-14 days may be helpful.
1.10 IV or greater: Positive - 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.
0050292Herpes Simplex Virus Type 1 Glycoprotein G-Specific Antibody, IgG by ELISA (HerpeSelect®) 0.89 IV or less: Negative - No significant level of detectable IgG antibody to HSV type 1 glycoprotein G.
0.90-1.10 IV: Equivocal - Questionable presence of IgG antibody to HSV type 1.  Repeat testing in 10-14 days may be helpful.
1.11 IV or greater: Positive - IgG antibody to HSV type 1 glycoprotein G detected, which may indicate a current or past HSV infection.
0050294Herpes Simplex Virus Type 2 Glycoprotein G-Specific Antibody, IgG by ELISA (HerpeSelect®) 0.89 IV or less: Negative - No significant level of detectable IgG antibody to HSV type 2 glycoprotein G.
0.90-1.10 IV: Equivocal - Questionable presence of IgG antibody to HSV type 2.  Repeat testing in 10-14 days may be helpful.
1.11 IV or greater: Positive - IgG antibody to HSV type 2 glycoprotein G detected, which may indicate a current or past HSV infection.
 Herpes Simplex Virus Type 1 and/or 2 Antibodies, IgG by Chemiluminescent Immunoassay 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.
2001633Lymphocytic Choriomeningitis (LCM) Virus Antibody, IgG < 1:10 Negative - No significant level of LCM virus IgG antibody detected.
≥ 1:10 Positive - Presence of IgG antibody to LCM virus detected, suggestive of current or past infection.
