The Mumps IgG test is performed using an ELISA (Enzyme Linked Immunosorbent Assay) test kit manufactured by Euroimmun Diagnostics (Germany). This ELISA test provides a quantitative in vitro assay for human antibodies of the IgG class against mumps virus in serum or plasma.
Mumps IgG test results are reported both qualitatively (Non-Reactive, Indeterminate or Reactive) and quantitatively together with an interpretation of the patient’s immune status based on the level of mumps IgG detected.
The unit of mumps IgG antibody measurement is RU/ml (Relative units/millilitre).
Mumps IgG Antibody Ranges and Result Interpretation:
||No Evidence of Immunity.(Indicates susceptibility|
||≥16 - <22 RU/ml
||Antibody levels in the indeterminate range for this assay may be insufficient to confer immunity.|
||Evidence of past infection / vaccination; evidence of immunity.|
N.B. These interpretations assume the absence of acute or recent infection
Quantitative results will ONLY be provided when the reason for testing is for the determination of immunity / immune status and this is clearly indicated on the PHOL requisition. If diagnosis is indicated or ticked quantitative IgG results will not be reported.
