If standard test results show blood in the urine could that be because of menstrual blood? or can the test decipher the difference?

Blood in urine : Menstral blood cannot be differentisted from blood that that might be found in the urine.

Sample quality: It's actually common for blood in the urine to be from menstruation, and you just need to alert your physician that this is likely.

It could be from : Menstrual blood or infection . The latter would show additional positive results on leucocytes/ white blood cells and nitrates on urine test. A repeat urine test is warranted for reassurance. Take care!
