The reference value of blood creatinine is 53~106μmol/L for male and 44~97μmol/L for female. 109μmol/L indicates that the blood creatinine is elevated, which can be divided into physiological and pathological aspects, and it is impossible to judge whether there is kidney disease only based on blood creatinine.
1. Physiological: after strenuous exercise or eating a lot of meat, blood creatinine may rise transiently, and usually return to normal after resting and controlling the diet, which is generally not kidney disease.
2. Pathological: including chronic glomerulonephritis, diabetic nephropathy, chronic kidney disease, etc. It is necessary to improve the urine routine, 24-hour urine protein quantification, renal ultrasound and other tests to further clarify whether it is kidney disease.
Patients with elevated creatinine should go to the hospital in time to see a doctor, under the guidance of a professional physician to clarify the cause and timely treatment.
