Seroprevalence of SARS CoV 2 Antibodies in Previously Undiagnosed Healthcare Workers

Seroprevalence of SARS CoV 2 Antibodies in Previously Undiagnosed Healthcare Workers

The purpose of this study is to identify healthcare workers with SARS CoV 2 antibodies who have not been previously diagnosed and are presumed COVID-19 negative, then determine the level of immunity in this population which could inform further decisions about widespread antibody testing in a healthcare worker population.

Enrolled participants will complete a survey gauging their level of confidence they will be antibody positive. Participants will then complete serologic testing for SARS CoV 2 IgG antibodies. The study will characterize the prevalence of antibody positivity in this population and assess whether there is a correlation between a pre-test confidence level using a Likert scale and actual antibody positivity.

Inclusion Criteria:

• Age ≥ 18 years old.
• Mayo Clinic employee in procedural and surgical area.
• Suspected COVID-19 exposure.
• Completed PCR test twice with negative results.

Exclusion Criteria:

- Refusal to participate in this study.
