Note1:
Interpretation:Antibody Index (AI) Explanation of Test Results
------------------- ---------------------------
<=0.8 Negative
0.9-1.0 Equivocal
>=1.1 Positive
IgG antibodies to EA are frequently present in acute IM and generally
absent in convalescence. The presence of antibodies in otherwise
healthy individuals usually indicates reactivation, especially when
paired with rising Antibody titer to Nuclear Antigen. EA Antibody
levels tend to rise and peak after 3-4 weeks, then decline and
usually dissipate after 6 months. Antibody to Nuclear Antigen
usually persists for life.
Antibody Index (AI) values reflect qualitative changes in antibody
concentration that cannot be directly associated with clinical
condition or disease state.

Note2:
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.

Note3:
Interpretation:Antibody Index (AI) Explanation of Test Results
------------------- ---------------------------
<=0.8 Negative
0.9-1.0 Equivocal
>=1.1 Positive
IgG antibodies to VCA are normally present in acute and convalescent
IM. The presence of antibodies in otherwise healthy individuals
usually indicates immunological exposure either as silent primary
infection or past exposure. Antibody levels tend to rise and peak
after 3-4 weeks, then decline and usually persist for life.
Antibody Index (AI) values reflect qualitative changes in antibody
concentration that cannot be directly associated with clinical
condition or disease state.

Note4:
Interpretation:Antibody Index (AI) Explanation of Test Results
------------------- ---------------------------
<=0.8 Negative
0.9-1.0 Equivocal
>=1.1 Positive
IgM antibodies to VCA are normally present in acute IM and generally
absent in convalescence. The presence of antibodies in otherwise
healthy individuals usually indicates immunological exposure either
as silent primary infection or reactivation. Antibody levels tend to
rise and peak after 3-4 weeks, then decline and usually dissipate
after 2-3 months.
Antibody Index (AI) values reflect qualitative changes in antibody
concentration that cannot be directly associated with clinical
condition or disease state.
