Support and tools for the COVID-19 diagnostics

We are committed to providing IVD test manufacturers with highest performance and quality antibodies, antigens and other raw materials for timely support of the SARS-CoV-2 outbreak. We can support our customers with MedixMAB antibodies and Lee Biosolutions control antigens applicable to COVID-19 diagnostics.

Relevant products

We can offer immunoassay raw materials that are suitable for SARS-CoV-2 related assay development. The recommendations below are based on the first-hand knowledge gained by Medix Biochemica’s team in China who are actively monitoring scientific data and regulatory recommendations published during the COVID-19 outbreak in China.

  • IgM, IgG, and IgA
    – Detection of antibodies against SARS-CoV-2 in serological tests
  • CRP
    – COVID-19 increases CRP levels, unlike viral diseases causing common colds
  • SAA
    – Elevated levels of inflammatory protein Serum Amyloid A have been detected in COVID-19 patients in China
  • D-dimer
    – Prognostic potential; increased D-dimer levels have been reported in severe cases in China

UPDATED May, 2020:

Our Covid-19 diagnostics product portfolio has been expanding. We are now able to provide a wider selection of SARS-CoV-2 recombinant antigens to support the IVD test manufacturers.
