Quantitative COVID-19 SARS-CoV-2 Antibody Pre and Post Cardiopulmonary Bypass

Overview

This study is designed to compare the levels of SARS-CoV-2 antibody prior to cardiopulmonary bypass and after cardiopulmonary bypass (CPB).

This study is designed to compare the levels of SARS-CoV-2 antibody prior to cardiopulmonary bypass and after cardiopulmonary bypass (CPB). During CPB the patients' blood volume is removed from the body and sent through the CPB machine. CPB consists of a pump (to keep blood moving) and oxygenator (to oxygenate blood). The oxygenator or CPB circuitry may effect antibody levels. In addition, patients on CPB experience hemodilution from blood transfusion and priming volume from the CPB circuit. Hemodilution may effect antibody levels. Prior to CPB, during standard of care lab drawn from standard of care arterial catheter, 0.5ml of plasma will be sent to the TJUH microbiology lab for Roche Elecsys Anti-SARS-CoV-2 immunoassay for pre-CPB quantitative antibody testing. On morning of postoperative day 1, during standard of care lab draw from standard of care arterial catheter, 0.5ml of plasma will be sent to the TJUH microbiology lab for Roche Elecsys Anti-SARS-CoV-2 immunoassay for post-CPB quantitative antibody testing. On morning of postoperative day 5, during standard of care lab draw, 0.5ml of plasma will be sent to the TJUH microbiology lab for Roche Elecsys Anti-SARS-CoV-2 immunoassay for post-CPB quantitative antibody testing. If patient is discharged from the hospital prior to postoperative day #5, this immunoassay will be omitted.
