My blood test showed higher level of protein. Was sent for urine test and showed protein in urine. I have had three kidney stones, but none currently.

Protein in urine. Requires follow up with quantification of amount - there are two ways to do this: cup of urine with protein to creatinine ratio mg/mg -- or a 24 hour urine collection. Both are meaningful. Blood tests need interpretation, also. High protein in blood could indicate an evolving disorder that requires characterization with electrophoresis. Urine protein should be characterized with electrophoresis.
