Depending on the overall efficiency
Normal kidneys, up to the age of 40 years, should have a rate of efficiency close to 100%. Of course, they are affected by age factors. It is possible that every 10 years, the rate decreases by 10%, even if there are no diseases. We calculate age and weight
There are five stages...the first is from (80 – 100)
The second (80 – 60)
The third (60 – 30)
Fourth (30 – 15)
Fifth (less than 15) g
If it is less than 15%, we say that there is a problem and a specialist doctor is required
