Ref. 100061-25

Rapid test for the qualitative detection of IgG and IgM antibodies against SARS-CoV-2 in human whole blood, serum or plasma specimens. For professional in-vitro diagnostic use only

COVID-19 IgG/IgM Rapid Test


COVID-19 serological tests allow to identify the presence of antibodies (IgG and/or IgM targeting the Nucleocapsid protein) produced by the immune system in response to SARS-CoV-2 virus and to take precautionary measures, waiting for a molecular test.

Recent studies have shown that in people infected with the virus, IgM and/or IgG antibodies appear within 19 days after the onset of symptoms (in 60% of cases within the first week and in 90% within the second week) and, while IgM levels decrease at the end of the infection, those of IgG remain high and therefore detectable.

Benefit of the test

Easy to use

Results in 10 minutes

COVID-19 emergency support

Track any asymptomatic subjects

Seroprevalence detection


Serological tests are a fundamental tool for both controlling asymptomatic individuals, possibly exposed to the virus in the last two weeks, and for seroprevalence investigations.

In the first case, these tests can be considered tools to support molecular tests, as they would allow to know the prevalence of the virus in a specific place, letting to adopt isolation measures and thus reducing any asymptomatic spread. The seroprevalence studies, on the other hand, are surveys in which a representative sample of the population is subjected to the test in question. Thanks to these analyzes it is possible to know the real lethality of the disease, the geographical spread and the spread within the different age groups.


COVID-19 IgG/IgM RAPID TEST is a lateral flow immunochromatographic device for the qualitative detection of IgG and IgM antibodies against SARS-CoV-2 in human whole blood, serum or plasma samples. This test consists of two components, an IgG component and an IgM component. During testing, the sample reacts with SARS-CoV-2 antigen coated particles in the test cassette.

Test format rapid immunochromatographic lateral-flow assay
Results reading time 10 minutes
Sample whole blood, serum and plasma
Antigen Nucleocapsid
Specificity 97.8%
Sensitivity 95.7%
Accuracy 97.3%


  • 25 test cassettes
  • 1 vial with dropper containing enough diluent to perform 25 tests
  • instructions for use


  1. Draw a blood sample by using the sterile lancet provided;
  2. Collect the sample indicated with the black line by using the capillary pipette provided;
  3. Deposit the collected specimen into the sample well (S) indicated on the test cassette;
  4. Add 2 drops of the diluent and wait 10 minutes before reading the result.


Negative anti-Nucleocapsid IgG and IgM levels are not present in the sample or they are present in very low concentrations, which are not detectable by the device.
Positive IgG and/or IgM antibodies have been detected in the blood sample.

The test has been carried out correctly when the instructions for use are followed. It includes the reading time and the interpretation of the results shown at the "RESULTS INTERPRETATION" section of the instructions for use.

A colored line will appear at the control region (C) on the test device, showing that the test performed correctly. The absence of the colored line suggests to repeat the test with a new device and a new sample.

The color and intensity of the lines do not affect the interpretation of the result. The test has to be considered positive regardless of the color intensity of the test line (T).
