Yes: Because the hemoglobin in red blood cells is a protein, if there is blood in the urine it can test positive for protein. You would need to have your urine retested when there is no blood in it to make sure about the protein.

Agree with Dr. R: Blood in urine will result is a positive test for protein as well. Have a healthy diet, exercise, drink plenty of water, have safe sex, and get HPV vaccine. Wish you good health! Nutrition: http://www.choosemyplate.gov/.

What do protein and blood in my urine mean?

Blood ; protein: This means there is a small amount of some source of blood ; protein in the urine ; the meaning of this needs to be looked at with any other lab abnormalities, signs/symptoms, clinical context. If nothing else abnormal, then blood with protein is entering your urine in some way. Are there symptoms like burning with urine, flank pain, recent infection, etc? See your doctor for more assistance.
