Brief summary

This is a multicenter cross-sectional study will randomly screen kidney function in adult patients with known risk factors for chronic kidney disease (CKD) within the Brazilian general population. Kidney function will be assessed using a point-of-care creatinine test at local healthcare facilities. Patients with abnormal test results will be referred for laboratory confirmation within three months and will undergo evaluation by the local nephrology team to determine the need for follow-up care.
