text: I'm unclear as to your test. If you are referring to the urine microalbumin (normal ratio of microalbumin to creatinine is 0-30), then 66 mean that the kidney has started to spill protein. This is the earliest stage of diabetic kidney damage. If not already on it, Hubby should be started on an ACE inhibitor (enalapril, lisinopril, captopril, etc.). These meds have been proven to delay/prevent further kidney damage. Of course, good control is always essential.
