Currently chronic kidney disease has been staged according to CKD, and blood creatinine 140 μmol/L should be further assessed for glomerular filtration rate, such as using the CKD-EPI formula. Based on the estimated glomerular filtration rate, it is judged to belong to CKD stage 3 of chronic kidney disease.
Blood creatinine is currently used as a basic indicator for renal function screening, but blood creatinine concentration is affected by uncontrollable physiological factors such as body muscle content and age, in addition to controllable exogenous creatinine. Clinically, further calculation of glomerular filtration rate is required for proper assessment of renal function.
Current international guidelines stage chronic kidney disease according to glomerular filtration rate, glomerular filtration rate greater than 90 ml/min is stage 1, 60~89 ml/min is stage 2, 30~59 ml/min is stage 3, 15~29 ml/min is stage 4, and less than 15 ml/min is stage 5.
Therefore blood creatinine 140 μmol/L is equivalent to chronic kidney disease CKD stage 3. Patients with abnormal blood creatinine are recommended to visit regular hospitals in time and standardize the treatment under the guidance of physicians.
