Diagnosis of Diabetic Nephropathy
How do you diagnose diabetic nephropathy?
The diagnosis is made by measuring the amount of protein (albumin) which are eliminated in the urine. It is desirable to collect the urine sample that occurs during the night.
- A value of albumin removal less than 20 micrograms per minute is normal.
- Values between 20 and 200 micrograms per minute is known as microalbuminuria or, which is, incipient renal injury.
- With numbers higher than 200 micrograms per minute speaks of macroalbuminuria or established diabetic nephropathy.
Sometimes it is necessary to measure kidney function. To do so, perform a urine collection 24 hours and the taking of a blood sample. With the results of these tests are calculated creatinine clearance. Keep in mind that other diseases other than diabetes, such as urinary tract infections can also alter the amount of protein in the urine.
Diet
In many cases where macroalbuminuria is present and detected a significant reduction in renal function, it is necessary the introduction of a diet low in protein.
