Is blood creatinine 85 μmol/L serious?

The reference value of blood creatinine is 53~106μmol/L for men and 44~97μmol/L for women, so blood creatinine of 85μmol/L belongs to the normal range and is not serious.
Blood creatinine can reflect glomerular filtration rate to a certain extent, which is one of the indicators commonly used in clinic to assess glomerular filtration function.
Blood creatinine is generally more constant in the body and can be divided into exogenous and endogenous creatinine. Exogenous will be affected by eating a large amount of meat, strenuous exercise, etc. and will fluctuate, but generally does not affect health.
When exogenous is stable, endogenous creatinine will be affected by glomerular filtration capacity, and when fluctuation occurs, it may be related to glomerular filtration function, which is generally a change in glomerular pathology.
If the blood creatinine is 85μmol/L, without other uncomfortable symptoms or abnormal laboratory tests, it is generally not serious. The fluctuation is not necessarily due to pathological reasons, don’t worry too much, but should improve the relevant examination in time to clarify the cause, so as not to delay the condition.
