NCT04453280

Brief Summary

The aim of the SARS-CoV-2-CZ-Immunity study is to determine the time profile of the presence of antibodies against SARS-CoV-2 in blood plasma by quantification of antibodies or performing a rapid test in COVID-19 cured patients.

Outcome Measures

Primary Outcomes (1)

  • Determination of the concentration of anti-SARS-CoV-2 antibodies in relation to the categories of cured patients.

    The primary outcome is the determination of the concentration of anti-SARS-CoV-2 antibodies IgG, IgM, and IgA classes in relation to the categories of cured patients according to the time from the date of cure from the COVID-19 disease to the date of examination.

    May 2020

Secondary Outcomes (2)

  • Determination of the concentration of anti-SARS-CoV-2 antibodies in relation to the age and to the severity of the disease.

    June 2020

  • The quantification of the dependence of the change in the concentration of anti-SARS-CoV-2 antibodies.

    June 2020

Other Outcomes (1)

  • The identification of potential donors of convalescent plasma.

Study Arms (2)

Cohort 1 - Prague and Central Bohemian Region

A population cohort of cured patients based on epidemiologically defined demographic parameters - Prague and Central Bohemian Region population

Diagnostic Test: Quantitative analysis of anti-SARS-CoV-2-antibodiesDiagnostic Test: SARS-CoV-2 diagnostic rapid test

Cohort 2 - South Moravian Region

A population cohort of cured patients based on epidemiologically defined demographic parameters - South Moravian Region population.

Diagnostic Test: Quantitative analysis of anti-SARS-CoV-2-antibodies

Interventions

Plasma sampling will be collected and archived for subsequent quantitative analysis of anti-SARS-CoV-2 antibodies - IgG, IgM and IgA.

Cohort 1 - Prague and Central Bohemian RegionCohort 2 - South Moravian Region

The rapid test detects the presence of antibodies against SARS-CoV-2 by the immunochromatographic reaction.
