Should i be worried if my doctor told me i have a small amount of protein in my urine?

Proteinuria: Protein is normally not found in urine. The usual system used to quantify protein is 0, trace, and then 1+ to 4+. So there is a source of protein in the urine and the meaning of this needs to be looked at with any other lab abnormalities, signs/symptoms, clinical context. Follow up with your doctor for any further evaluation or treatment.
