Quantitative serological test with CLIA method of IgG and IgM

What are they?
These are tests that detect the presence in the serum (a part of the blood) of antibodies (Immunoglobulins, Ig) produced by the immune system to defend itself from what comes from outside (Antigens), and that can be a threat, such as the SARS-CoV-2 and therefore indicate whether or not a subject has come into contact with an infectious agent.

The quantitative serological test with CLIA method is done through the CLIA method.

The quantitative serological test with CLIA method is performed through a venous sampling from the arm performed by a nurse and a subsequent laboratory analysis of the blood tube with CLIA method carried out at the authorized laboratory of the MultiMedica Group: the Polo Scientifico Tecnologico of Milan. These tests, in addition to detecting the presence of IgM and IgG antibodies, also measure the amount of IgG.

The antibodies called “IgM” are produced in the initial phase of the infection, are found in the blood starting from 3 or 6 days after the appearance of symptoms and then tend to disappear within a few weeks. The other antibodies, called “IgG”, are produced later and are found in the blood starting from a couple of weeks after the onset of symptoms (but may appear even earlier) and should then remain for a long time.

The serological test can provide the following results:

  • IgM and IgG negative: there has been no infection, or the exposure to the pathogen occurred too short time ago and a detectable immune reaction has not yet been developed, or the level of antibodies produced is too low to be detected by the test;
  • only IgM positive: exposure to the antigen is very recent.
  • IgM and IgG positive: the infection is ongoing and has been contracted recently;
  • only IgG positive: the infection has been there but it is not recent.

Depending on the results, other tests may be needed to arrive at an accurate diagnosis.

The test report is available within 24h – max 48h (working) after the examination. It is possible to obtain the report through 2 ways:

  • personally by collecting the paper report at the test point located at the entrance of the MultiMedica facility where the test was performed, or by a person other than the patient with a special proxy issued by the patient
  • personally by e-mail

No, there is no need for fasting and no need to stop taking medications.

Regional regulations in force foresee that, in case of a POSITIVE test result for IgM and/or IgG, the possible contagiousness of the patient must be verified by searching for viral RNA with a molecular technique (i.e. execution of an oro-pharyngeal swab).

In case of POSITIVE result to the serological test (presence of IgM and/or IgG), the patient must, therefore,

  • submit autonomously to the precautionary home isolation measure until the negative result of the molecular test (gold-pharyngeal swab), as well as
  • submit as soon as possible to the execution of an oro-pharyngeal swab for viral RNA research.

For details on how to behave during the period of fiduciary isolation, please contact your doctor.

The legislation also requires that, in case of a POSITIVE result to the serological test, the patient’s data, the test report, the date of the start of the isolation of trust and the date scheduled for the performance of the gold-pharyngeal swab are communicated by the laboratory of MultiMedica to the ATS of competence of the patient.
