Clinical Trial Summary

This study aim to recruit all Electronic Medical Record of patients who underwent for 51chromium ethylenediamine tetra acetic acid (51Cr-EDTA) imaging at the Nuclear Medicine Centre, University Malaya Medical Centre from September 2016 to September 2021. The data that collected will be analyzed to develop and validate a new equation to estimate Glomerular Filtration Rate that specifically for Malaysian multiracial population.

Description:

List of patients who underwent for 51Cr EDTA imaging at the Nuclear Medicine Centre, University Malaya Medical Centre from September 2016 to September 2021 will be obtained from relevant department. All patient's Electronic Medical Record (EMR) will be evaluated for recruitment into the study. Demographics data of the patients that will be collected include age, gender, height, weight, and ethnicity. The clinical data that will be collected include CKD aetiology, background comorbidities, and vitals sign and laboratory data includes the renal function test. The 51Cr- EDTA readings were also recorded. If there are multiple measurements of scans performed, the latest 51Cr-EDTA taken. The renal function test must be within three months of when the 51Cr-EDTA imaging was conducted. Patients will be randomized into a development and validation cohort using a random number generated in Microsoft Excel. In the development cohort, a new equation will be developed using a nonlinear regression model utilizing a generalized least squares algorithm. Internal validation will be performed in the validation cohort, by comparing the bias, precision, and accuracy of the new equations and the other established equations to the measured GFR.
