Hi, Dr. Rynne. I Am Concerning About My Grandson's Health

Hi, Dr. Rynne. I am concerning about my grandson's health after he got the results of urine specimen...There are some abnormalities as elevated protein 1+(A), elevated ketones 2+(A), mucus and amorphous UA present, crystals CA oxalate UA 1+ (A)...My grandson is 3.7 years-old and recently he had a stomach flu; however, more than 6 months ago, I have noticed his urine was cloudy and so small in quantity, with bad odor...I would like to know what it means?
