Interpretive Data
Individuals infected with HSV may not exhibit detectable IgG antibody to type-specific HSV antigens 1 and 2 in the early stages of infection. Detection of antibody presence in these cases may only be possible using a non-type specific screening test.
Component | Interpretation |
---|---|
Herpes Simplex Virus Type 1 Glycoprotein G-Specific Antibody, IgG by CIA | 0.89 IV or less: Negative - No significant level of detectable IgG antibody to HSV type 1 glycoprotein G. 0.90-1.09 IV: Equivocal - Questionable presence of IgG antibody to HSV type 1 glycoprotein G. Repeat testing in 10-14 days may be helpful. 1.10 IV or greater: Positive - IgG antibody to HSV type 1 glycoprotein G detected, which may indicate a current or past HSV infection. |
Herpes Simplex Virus Type 2 Glycoprotein G-Specific Antibody, IgG by CIA | 0.89 IV or less: Negative - No significant level of detectable IgG antibody to HSV type 2 glycoprotein G. 0.90-1.09 IV: Equivocal - Questionable presence of IgG antibody to HSV type 2 glycoprotein G. Repeat testing in 10-14 days may be helpful. 1.10 IV or greater: Positive - IgG antibody to HSV type 2 glycoprotein G detected, which may indicate a current or past HSV infection. |
