Kidney biopsy findings. (a) Two glomeruli in the center reveal crescents: a cellular crescent in the glomerulus to the left, and a fibrocellular crescent to the right. Surrounding tubules reveal distension and flattening of the epithelium (periodic acid−Schiff stain, original magnification ×200). (b) Immunofluorescence staining for IgG reveals no significant staining in depicted glomerulus or surrounding tubular basement membranes (fluorescein isothiocyanate, original magnification ×200). (c) Representative section showing negative immunohistochemistry staining for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleocapsid protein after antigen retrieval (original magnification ×200). (d) Lung tissue from a known SARS-CoV-2−infected patient served as positive control for immunohistochemistry method (original magnification ×400).
