Elevated creatinine on physical examination may be misdiagnosed, but the probability is not high.
Creatinine is the product of muscle metabolism in the body, creatinine elevation in physical examination may be caused by eating a lot, or strenuous exercise before the physical examination, at this time creatinine is not able to truly reflect the function of the kidneys. If you exclude the above physiological factors, creatinine elevation may be due to the decline in renal function.
The high creatinine in physical examination is mistaken as test error, mainly because kidney disease is a kind of insidious disease, patients often have no subjective symptoms, only through the corresponding examination can be found.
If you strongly suspect that the test error, you can review the kidney function again after resting well, avoiding cold and fever, avoiding strenuous exercise and eating a lot of high protein food. If there is any abnormality, it is recommended to consult the hospital in time to find out the cause and treat the symptoms.
