Special Precautions/Comments:

N.B. If patient is pregnant, please ensure this is stated in clinical details along with if they have has recent measles contact.

Interferences: Interference may be encountered with certain sera containing antibodies directed against reagent components. For this reason, assay results should be interpreted taking into consideration the patient’s medical history and the results of any other tests performed.

Method: Enzyme-Linked Fluorescent Assay (ELFA). Calibration: VIDAS assay kit standard. EQA scheme: NEQAS.  IQC: VIDAS commercial preparations.

Interpretation: Results are reported as NOT detected – SUSCEPTIBLE to measles (negative) or DETECTED – Consistent with PAST infection/immunisation (positive). Samples reported as Equivocal will be referred to Newcastle Hospitals Virology Service for confirmatory testing using an alternative method.

Additional Information:

Measles (rubeola), a member of the paramyxovirus group, is a highly communicable airborne disease . At one time measles was a very common childhood disease, but the introduction of a vaccine in 1963 and the subsequent vaccination programs of the late 1970s drastically reduced the number of reported cases. However, even with these efforts the disease has not been totally eliminated. VIDAS Measles IgG (MSG) is a qualitative test for the detection of IgG antibodies to measles. A positive result with the VIDAS Measles IgG assay indicates the presence of anti-measles IgG antibodies.
