ALB, albumin; ANA, anti-nuclear antibody; ANCA, anti-neutrophil cytoplasmic antibody; BUN, blood urea nitrogen; BACT, bacteria; CO2CP, carbon dioxide combining power; CRP, C-reactive protein; dsDNA, double-stranded DNA; FCM, flow cytometry; GBM, glomerular basement membrane; HGB, hemogloblin; HbA1c, hemoglobin A1c; IFE, immunofixation electrophoresis; M, microscopic; Neut, neutrophil; NGS, next-generation sequencing; NA, not applicable; PLT, platelet; PCT, procalcitonin; RBC, red blood cell; SCr, serum creatinine; SG, specific gravity; UACR, urinary albumin-to-creatinine ratio; UPCR, urinary protein-to-creatinine ratio; UTP, urinary total protein; WBC, white blood cell. NGS results were classified as high confidence by the validated internal analytical pipeline of the hospital laboratory. Escherichia coli was detected in whole blood (5,033 specific reads) and urine (2,522 specific reads). Values outside the reference range are shown in bold. Upward and downward arrows indicate values above and below the reference range.
