Reader Offer – Anti-SARS-CoV-2 IgG and IgM antibody test

The Fertility Hub are delighted to have secured a special rate for IVF clinics to purchase OnSite® COVID-19 IgG/IgM Rapid Tests. These are manufactured by CTK Biotech Inc (USA) and distributed by Avonchem Ltd (UK).

What is it?

An inexpensive and convenient on site ‘in situ’ test for anti-SARS-CoV-2 IgG and IgM antibodies in human plasma or whole blood.

The test is intended to be used by healthcare professionals as an aid in the diagnosis of individuals who are suspected to have had a COVID19 infection.

How does it work?

Each test comes as a small plastic cassette. Simply place two drops of blood from a finger-prick into the sample well followed by two/three small drops of the supplied buffer fluid. The mixture will then seep up the centre of the cassette.


The results are available visually after ten to fifteen minutes with no need for any laboratory involvement. If the antibodies are present, they will bind to the antibodies on the test strip, leaving a visible test line.

There are separate test lines for IgG and IgM and only one needs to be visible for a positive result. This is useful because the antibodies are present in differing concentrations at different times, so it is important to test for both. If the patient has not experienced COVID-19 infection, no biomarkers should be present in their blood and no test line will be visible.
