| 22287 | CAT_S_COVIDAB_NUC | Interpretive result for Nucleocapsid Antibody/Possible past infection by SARS-CoV-2 virus | 1) Interpretive result (positive or negative) for presence of nucleocapsid antibody; assessed by Abbott SARS-CoV-2 IgG assay. This interpretation does not confirm or exclude past infection by the SARS SARS-CoV-2 virus. 2) After assay with Abbott SARS-CoV-2 IgG (showing positive result) followed by assay with DiaSorin SARS-CoV-2-S1/S2 IgG (showing negative result) the combined interpretive result is INDETERMINATE for past infection by SARS-CoV-2 virus. | Text | positive, negative, indeterminate | Index (S/C) |

| 22288 | CAT_S_COVIDAB_SPIKE | Interpretive Result for RBD Antibody | Interpretive result (positive, negative) to the presence of IgG antibodies of the Receptor Binding Domain (RBD) of the S1 subunit of the spike protein of the SARS-CoV-2 from the Abbott SARS-CoV-2 IgG II Quant assay. This interpretation does not confirm nor exclude possible past infection by SARS CoV-2 virus. | Text | positive, negative |
