Interpretation:Antibody Index (AI) Explanation of Test Results
------------------- ---------------------------
<=0.8 Negative
0.9-1.0 Equivocal
>=1.1 Positive
IgG antibodies to NA are rarely present in acute IM and normally
rise during convalescence. The presence of antibodies in otherwise
healthy individuals usually indicates past exposure. Antibody levels
will rise to a plateau level in three months to a year and will
normally persist for life.
Antibody Index (AI) values reflect qualitative changes in antibody
concentration that cannot be directly associated with clinical
condition or disease state.
