Table 1.

The results of laboratory testing for the first 172 h of hospitalization. Neutrophil counts were normal, lymphocytopenia and thrombocytopenia were present, and inflammatory markers, such as CRP, Procalcitonin, Ferritin, and high D-dimer, peaked at 96 h after the illness began. Normal prothrombin time (PT), partial thromboplastin time (aPTT), and international normalized ratio (INR).
