Blood creatinine at 56μmol/L belongs to the normal range. The normal level of creatinine is 53~106μmol/L for men and 44~97μmol/L for women. The standard value of creatinine varies from hospital to hospital, so you can check the reference value according to your local hospital. Blood creatinine refers to the amount of blood creatinine in the blood, which is the most commonly used indicator of kidney function. Blood creatinine is produced by muscle metabolism, muscle metabolism will produce creatinine after human activity, if consume too much meat will also lead to the rise of blood creatinine, about every 20g of muscle metabolism will produce 1mg of creatinine. Blood creatinine, as a basic indicator of renal function screening, 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. Preventing the rise of blood creatinine requires, in daily life, drinking more water, eating more light food, such as fresh fruits and vegetables, keeping regular diet, using nephrotoxic drugs with caution, paying attention to maintaining stable blood pressure and blood glucose, and regular rechecks. Patients with any discomfort, it is recommended to regular hospitals, under the guidance of the physician to improve the relevant examination, targeted treatment.
