Compared with creatinine and glomerular filtration rate, glomerular filtration rate is more accurate because creatinine is easily affected by the patient’s age and body weight, while glomerular filtration rate is a combination of the patient’s age, body weight, and serum creatinine value, so it is relatively more accurate.
Glomerular filtration rate in adult resting state is about 120ml/min for men and about 10% lower for women. Glomerular filtration rate is commonly used in clinical practice to evaluate kidney function. If it is lower than 90 ml/min, it is considered to have renal failure, which may be acute renal failure or chronic renal failure, and needs to be determined based on the patient’s medical history and ancillary tests.
Another indicator commonly used in clinical evaluation of renal function is creatinine, the normal value of creatinine in men is 53-106 μmol/L, and the normal value in women is 44-97 μmol/L, with a slight difference in the reference range of each hospital. However, elevated creatinine can be affected by many factors, such as high protein diet, strenuous exercise and so on.
Elevated creatinine mostly indicates renal failure, on the contrary, decreased glomerular filtration rate mostly indicates renal failure. Regardless of the test method, if the test is abnormal, it is recommended that the patient should go to the hospital in time, and under the guidance of the doctor to improve the examination and symptomatic treatment.
