Serum Creatinine Is Around 100 Is Renal Failure?

After checking renal function in different regions and hospitals, you will find that there are many upper limits for the reference value of serum creatinine, ranging from more than 80 to more than 130. The same serum creatinine value, such as 100 μmol/L, is normal in one hospital, but it exceeds the standard according to the standard of another hospital. Is there any renal failure? Would you like to convert it?

Today, I will help you figure out this seemingly vague problem.

In fact, the reason why the reference value of serum creatinine is different in different places has little to do with the test, mainly because the physique of residents in different places is different. The muscle content of northern residents is higher, and the reference value of serum creatinine is naturally marked higher.

The instruments and reagents of various hospitals have little effect on the creatinine value, and the laboratory departments in various places almost measure the serum creatinine value according to the same set of procedures. The same blood sample, no matter which hospital in which region is sent, will give similar or the same results.

Therefore, no matter where you check, just look at the rise and fall of your serum creatinine value, and you don't need to convert it because of different reference values.

So the serum creatinine is around the upper limit of the reference value, is it renal failure?

Since serum creatinine is not a very accurate indicator, when the serum creatinine is around 100 μmol/L, the normal range does not mean that the renal function is normal at all, and the excess does not necessarily mean renal failure.

To make a diagnosis, it is necessary to look at test items such as cystatin C, glomerular filtration rate or endogenous creatinine clearance rate, and renal B-ultrasound to get accurate results.

Especially the glomerular filtration rate, which is the gold indicator for measuring renal function, and the filtration rate exceeding the standard is the real problem of renal function.
