Refer to:
- Reference Range:
Respiratory Syncytial Virus IgG Antibody: - Less than 0.90 IV: Negative = No significant level of respiratory syncytial virus IgG antibody detected, - 0.90-1.10 IV: Equivocal = Questionable presence of respiratory syncytial virus IgG antibody detected. Repeat testing in 10-14 days may be helpful - Greater than 1.10 IV: Positive = IgG antibodies to respiratory syncytial virus detected, which may suggest current or past infection.
Respiratory Syncytial Virus IgM Antibody: - Less than 0.90 IV: Negative = No significant level of respiratory syncytial virus IgM antibody detected - 0.90-1.10 IV: Equivocal = Questionable presence of respiratory syncytial virus IgM antibody detected. Repeat testing in 10-14 days may be helpful - Greater than 1.10 IV: Positive = IgM antibodies to respiratory syncytial virus detected, which may suggest current or recent infection. - Additional Test Info:
