Re: Tests to Determine Exact Performance of Kidneys.
There is a calculated test also done called an eGFR (estimated glomerular filtration rate). Basically, if this calc and the creatinine and urea are normal, then your kidneys are assumed to be functioning correctly. Why are you concerned about your kidneys? Do you have diabetes, high blood pressure, other issues? If you don't have other issues and the blood work is normal, then there is no need to worry.
