"""SARS-CoV-2 (Severe acute respiratory syndrome coronavirus) Negative/Non-Reactive ControlSARS-CoV-2 Negative/Non-Reactive Control is intended for use with in vitro assays for determination of Total antibodies to SARS-CoV-2 (Severe acute respiratory syndrome coronavirus).SARS-CoV-2 Negative/Non-Reactive Control is unassayed without target values and is suitable for use on various analysers. SARS-CoV-2 Negative/Non-Reactive Control is useful in determining the precision of testing systems and allows performance monitoring of multiple test systems.SARS-CoV-2 (Severe acute respiratory syndrome coronavirus) Positive/Reactive ControlSARS-CoV-2 Positive/Reactive Control is intended for use with in vitro assays for determination of Total antibodies to SARS-CoV-2 (Severe acute respiratory syndrome coronavirus).SARS-CoV-2 Positive/Reactive Control is unassayed without target values and is suitable for use on various analysers.
