The fluctuation of blood creatinine in 90~119μmol/L is normal if it is caused by physiological conditions such as muscular athletes, etc. and can be noted for review; if it is a pathologic condition, the possibility of chronic kidney disease should be considered. It is necessary to perform 24-hour urine creatinine test to calculate endogenous creatinine clearance, or ECT to detect glomerular filtration rate to make a judgment.
Blood creatinine generally refers to endogenous creatinine, which is mainly produced by muscles, breathing in daily life, heartbeat, etc. Creatinine is generally filtered by glomeruli and excreted with urine, so to some extent, creatinine can reflect the kidney condition.
The fluctuation of blood creatinine between 90~119μmol/L is related to many factors. Physiological conditions such as muscular athletes, eating too much meat, strenuous activities, etc. are normal phenomena at this time, so just take a light diet, pay attention to rest, and have a regular recheck.
Blood creatinine fluctuation in 90~119μmol/L if exclude the possibility of physiological factors, need to consider the possibility of chronic kidney disease, this time can be carried out 24 hours urine creatinine test to calculate endogenous creatinine clearance, or ECT test glomerular filtration rate, or combined with renal ultrasound to make a comprehensive judgment, if necessary, need to improve the renal puncture biopsy, to clarify the cause of the disease.
If the blood creatinine is abnormal, it is recommended to go to the regular hospital in time, and follow the doctor’s instructions for standardized treatment.
