OD ratio indicates the ratio of the extinction of the patient sample over the extinction of the calibrator. B) Neutralization assay results. For each patient type, an outlined symbol indicates a negative test result, gray symbol a borderline result, and black symbol a positive result, as tested according to ma

Figure. Antibody response against severe acute respiratory syndrome coronavirus 2 at 8 weeks postinfection among patients and controls in South Korea. A) Serologic diagnostic test (ELISA) results. OD ratio indicates the ratio of the extinction of the patient sample over the extinction of the calibrator. B) Neutralization assay results. For each patient type, an outlined symbol indicates a negative test result, gray symbol a borderline result, and black symbol a positive result, as tested according to manufacturer recommendation. Bars represent mean values and SE. From each patient group other than the completely asymptomatic group, 3–4 patients were randomly selected for neutralization assay. The controls included 1 healthy volunteer and 2 patients with MERS. Ab, antibody; MERS, Middle East respiratory syndrome; OD, optical density.
