What researchers measure

Primary outcomes

  1. Number of Participants With SARS-CoV-2 IgG Antibodies

    Prevalence of SARS-CoV-2 IgG antibodies by serology testing in participants at the time of study enrollment or 3 months later

    Time frame: Serology Test #1 (Study Enrollment) and Test #2 (3 months apart)

Secondary outcomes

  1. Differences in Sex Between IgG Antibody-positive vs. Negative Participants

    Secondary outcomes included differences in the survey responses between IgG antibody-positive and -negative participants. These included demographics such as sex.

    Time frame: Survey completed before or on day of serology testing asking about information from January 1, 2020 to May 5, 2020

  2. Number of Asymptomatic Participants With Positive Antibody Serology

    Number of asymptomatic participants with positive antibody serology at either the study enrollment timepoint or 3 month timepoint

    Time frame: Serology Test #1 (Study Enrollment) and Serology Test #2 (3 months apart)

  3. Percentage of Antibody-positive Participants Who Subsequently Develop COVID-19

    Percentage of antibody-positive participants who subsequently develop COVID-19 at either the study enrollment timepoint or the 3 months time point

    Time frame: Serology Test #1 (Study Enrollment) and Serology Test #2 (3 months apart)

  4. Differences in Race Between IgG Antibody-positive vs. Negative Participants

    Secondary outcomes included differences in the survey responses between IgG antibody-positive and -negative participants. These included demographics such as race.

    Time frame: Survey completed before or on day of serology testing asking about information from January 1, 2020 to May 5, 2020

  5. Differences in Average Number of Adults in Household Between IgG Antibody-positive vs. Negative Participants

    Secondary outcomes included differences in the survey responses between IgG antibody-positive and -negative participants. These included demographics such as number of adult household members.

    Time frame: Survey completed before or on day of serology testing asking about information from January 1, 2020 to May 5, 2020

  6. Differences in Comorbidities Between IgG Antibody-positive vs. Negative Participants

    Secondary outcomes included differences in the survey responses between IgG antibody-positive and -negative participants. These included comorbidities.

    Time frame: Survey completed before or on day of serology testing asking about information from January 1, 2020 to May 5, 2020

Other outcomes

  1. Participants Who Were Eligible for in Plasma Donation

    Individuals who tested positive for COVID-19 who may be eligible for convalescent plasma donation

    Time frame: Serology Test #1 (Study Enrollment) and Test #2 (3 months apart)
