Blydt-Hansen et al. used ELISA to investigate biopsy-proven TCMR from urinary proteomic profiles of 51 paediatric kidney transplant recipients identifying an increased creatinine/CXCL10 ratio in both subclinical and clinical TCMR groups compared to non-TCMR patients [26]. The gene discussed is CXCL10; the disease is kidney transplant.
