can blood in the urine cause a false positive for protein in the urine?

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/.
