    Because in humans, menstrual blood is different from 'normal blood' - menstrual blood is actually the lining of the womb that is discarded by the body if fertilization has not occurred (that is why it is darker in colour).

    No, it's not part of a menstrual cycle, you should see a vet as soon as possible.

    I would think that they could check if there is uterus juice in it too, then it would be menstrual

    They've found blood in mine before and just asked when my last period was and when the next one is expected.

    They can't determine a difference. That's why the doctor asks the patient if she is on her menses. If she is not, and there is blood...possible other source.

  • If it is an emergency they will cathederize the woman or rabbit and get a sample that way. Otherwise they will wait untill the woman or rabbit is no longer menstrating.

    normally if a doctor finds blood in your urine they will continue to check your urine to see if it carries on also they will do blood tests to check for other things because blood in the urine can be a sign of kidney disease but you would normally show traces of protein if it was kidney problems aswell.

    A routine UA will not differenciate between types of blood. If they suspect something that they really need to know if it is blood in your urine, they will do an in and out catheter and get the urine sample that way.

    Menstrual blood comes from the vagina, urine from the urethra. The two are separate openings, and with a tiny bit of care can be kept separate.
