LIAISON® Sars Cov-2 Immunodiagnostic Test - Diasorin


COVID-19 is a contagious viral illness caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).  In order to accurately diagnose COVID-19 specialized testing is needed as many of its symptoms, are similar to those of a common flu. Some individuals have no symptoms at all whereas others may experience fever, cough, sore throat, loss of the sense of smell, general weakness and fatigue and muscular pain. In the most severe cases, severe pneumonia, acute respiratory distress syndrome, sepsis and septic shock, all of which potentially lead to death.

Early and accurate diagnosis, together with confirming vaccine effectiveness, are crucial to supporting medical decisions and preventing the diffusion of SARS-CoV-2.

How it works

The LIAISON® SARS-CoV-2 assays are highly effective chemiluminescence testing solutions to help contain the COVID-19 pandemic.  The exclusive immunoassays provide both a fully automated diagnosis of COVID-19 in suspected cases and the quantitative determination of the immune status of infected and vaccinated individuals.

Fully automated Ag and IgG testing


Early diagnosis on a high-throughput platform

Use within the first ten days of the onset of symptoms, LIAISON® SARS-CoV-2 Antigen Ag delivers 136 tests per hour. The all-in-one process runs on the fully automated LIAISON® XL chemiluminescence analyzer for greater testing efficiency and overall accuracy.


Capture the entire population of antibodies

The high sensitivity and specificity of our innovative IgG antibody detection assay ensures fast, accurate results. In addition, because the capture antigen is the Trimeric Spike protein, it offers greater diagnostic precision and better detection of the antibodies.


Innovative bio-sampling approach to better diagnostics

With the high performance of our exclusive assays and their all-inclusive Reagent Integral format, Diasorin guarantees consistent, high-quality diagnostic results while preventing waste.
