Protein 1+ urine screen, trace ketones. 53 yr old male. What does this mean. Dr didn't seem to concerned. Thanks.

Proteinuria. If you don't have longstanding hypertension or diabetes and a urinalysis and microscopic examination of your urine is otherwise normal but proteinuria persists on a repeat test, which I recommend now, your urine should have an electrophoresis and immunoelectrophiresis examination as disorders like multiple myeloma or amyloidosis may be the cause of the protein in the urine. Early diagnosis importa.
Agree with Dr. B. All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Talk to the doctor who ordered the tests. Having said that, it do not have diabetes or high blood pressure it would be safe to wait for 6 months to repeat the test. Drink enough water daily so that your urine is mostly colorless.
Protein in urine. It depends on your medical history, if you have diabetes or hypertension or kidney stones/disease, you can have protein in the urine, however if you do not have any chronic medical condition, you will need to repeat the test within a few months and it is usually better if it is quantified to see exactly how much protein is in your urine. this can be done with another simple urine test. .
