What test procedure is used for Aelysa?

When you have your blood tested for SARS-CoV-2 antibodies, you want to be sure that the test result is reliable. We at AELYSA Bioassays therefore use a laboratory-based ELISA test and not a so-called "quick test".

What is ELISA?

ELISA stands for Enzyme-Linked Immuno-Sorbent Assay, a procedure in which carefully selected enzyme, antigen and antibody compounds are used to enable the precise detection of SARS-CoV-2 specific antibodies. The accuracy of such ELISA tests is generally considered to be exceptional (>99%). We only use CE-IVD certified and validated ELISA tests to test blood samples for antibodies against SARS-CoV-2. We test for two different types of IgG antibodies against SARS-CoV-2: one type targets the envelope of the coronavirus (spike protein), the second type targets the inner region of the coronavirus (N protein).

Many providers only test for one type of IgG antibody and may report a negative test result even though your body has produced the other type of IgG antibody.

Of course, our test protocols are continuously adapted based on the latest research and knowledge about SARS-CoV-2 and we use test reagents and equipment only after internal quality control.
