Figure 3. Dynamics of laboratory biomarkers of 239 SARS-CoV-2 cases. Scatter plots of C-reactive protein (A), albumin (B), lymphocytes (C), and blood urea nitrogen (D) in older and younger patients are illustrated on days 0, 7, and 14. Blood tests on days 0, 7, and 14 were conducted for 239, 229, and 54 patients, respectively. Laboratory biomarkers on day 14 were assessed for 54 patients who had positive SARS-CoV-2 and remained in hospital on day 14.
