The normal range of different units of urinary creatinine is not the same, the normal range for men is: 7000-18000umol/d (800-2000mg/d), the normal range for women is 5300-16000umol/d (600-1800mg/d), and it is not possible to judge whether it is normal directly from the urinary creatinine of 10,000+. Urinary creatinine refers to the creatinine in urine, and creatinine is mainly an indicator for detecting kidney function. Clinical usually take blood creatinine to evaluate renal function, while the clinical application of urinary creatinine is not much, its main role is as a parameter to calculate other important indicators. For example, albumin/urinary creatinine ratio and endogenous creatinine clearance can be calculated using urinary creatinine. Urinary creatinine is an important indicator of creatinine excretion by the kidneys, however, it is not absolute, because urinary creatinine is easily affected by many factors, and there is also the possibility of renal disease, so if you want to assess kidney function, it is more meaningful to test blood creatinine. If the urine creatinine is abnormal and exceeds the normal range, it is recommended to consult a doctor in time to find out the cause of high urine creatinine.
