Proteinuria is the protein in the urine when it exceeds the level of 150 mg/day.Proteinuria can be checked for free proteins like protein C or particularly albumin.More proteins in the urine could indicate that the kidneys are failing.Proteinuria is not a disease but a symptom that indicates underlying pathology.Proteinuria may occur in association with other symptoms like hematuria, edema, hypertension, hypoalbuminemia, hypercholestrolemia, hyperlipemia,elevated serum creatinine and ASO.So there is really very long differential for proteinuria only.So tell me your symptoms and I would be able to help you as it would be very stupid to threaten you about all the startling medical terminology.
This is what I know about protein urine testing. Urine protein testing is used to help evaluate and monitor kidney function, and to help detect and diagnose early kidney damage and disease. If the level is high, the doctor may order a secondary test to determine which proteins are being excreted and in what quantities. Greater than 1200 appears high.
However, rereading your post I am unsure if you are mixing the tests urine protein against urine keytones? Keytones present in the urine means your body is expelling excess sugar via your urinary tract.
Are you diabetic or being considered a diabetic?
Best to call your doctors office for an explanation.
