Negative urine protein and blood creatinine of 65μmol/L are generally not kidney disease. Blood creatinine is commonly used to evaluate the glomerular filtration function, under normal circumstances, the normal level of blood creatinine reference value for men is 53~106μmol/L; reference value for women is 44~97μmol/L. When there are various reasons causing problems in glomerular filtration function, the creatinine in the blood cannot be excreted from the urinary system smoothly. When the glomerular filtration function is in trouble due to various reasons, creatinine in the blood can not be excreted from the body by the urinary system smoothly, so that creatinine in the blood rises. A blood creatinine of 65 μmol/L is within the normal range and generally indicates normal renal function. The normal value of urine protein shows that is negative, if the urine protein test result is positive, it means that the excessive protein that should not appear in the urine, from the urinary system into the original urine and excreted with the urine, often suggests that there may be kidney disease. If the kidney function, urine routine test results are abnormal, it is recommended to consult a regular hospital in a timely manner, under the guidance of the doctor to clarify the cause of the disease, and targeted treatment or treatment.
