It is usually not possible to determine the stage of chronic kidney disease simply based on the blood creatinine 163 μmol/L. The stage of chronic kidney disease is usually judged based on glomerular filtration rate.
Creatinine is the metabolic end product of creatine in muscle tissue. Creatinine does not bind with protein in the blood and can pass freely through the glomerulus, which is the most commonly used indicator to indirectly reflect the glomerular filtration function. When the glomerular filtration function is impaired, the body’s serum creatinine may be elevated, suggesting the presence of renal insufficiency.
Normal values for creatinine range from 44 to 97 μmol/L for women and 53 to 106 μmol/L for men, with a creatinine level of 163 μmol/L indicating impaired renal function. Clinically, laboratory data such as urea and creatinine are commonly used to estimate glomerular filtration rate by various formulas in combination with patient’s gender, age, ethnicity and other information, so as to stage chronic kidney disease.
Therefore, based on creatinine 163μmol/L alone, it is usually not possible to determine the stage of chronic kidney disease, and further kidney function related tests are needed. If you find elevated creatinine level, it is recommended to go to regular hospitals for timely consultation, improve the examination to identify the cause of the disease, and then give targeted treatment or therapy under the guidance of the doctor.
