    Innovating to deliver
    high-quality reliable testing technology.

    IMMUNOSTEP mission is to develop and market innovative products that improve diagnostic and clinical research performance and we will continue to work every day to deliver high-quality technology in order to fight against the global health emergency by assuring reliable results.


    Our Commitment:
    Reliability and Innovation

    The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a new virus that belongs to the family of coronaviruses, of the genus Betacoronavirus, which emerged in China in the city of Wuhan, Hubei province in December 2019 and was It has spread throughout the world until being declared by WHO as a pandemic in March 2020.

    In response to the Covid-19 pandemic, CSIC research groups have worked in collaboration with Immunostep to develop these serological tests capable of detecting specific SARS-CoV-2  antibodies  and monitoring immune responses with an estimated accuracy of 98%.








    Detecting SARS-CoV-2 immune response with an estimated accuracy of nearly 100%.


    High sensitivity and specifity targeting highly antigenic structural and  non-structural proteins.


    Very early antibody detection from the symptoms onset identifying IgG, IgA and IgM immunoglobulins.

    Research and Development

    Our goal is to improve serology testing performance by innovating and adapting new technology to collaborate building meaningful clinical investigation. 

    We strongly believe validity and realiability of assessment methods must be the most important characteristics of a well- designed assessment procedure, and so we build our workflows in order to achieve the highest quality in all our products and devices.

    CE/IVD kits are only suitable for clinical use in European Union and countries with EU conformity recognition agreements. Manufactured in Spain by Immunostep under CSIC Patent Licence.
