Just for some comparative information, my urine dip test at the CFRC medical came back positive for blood and urine.
I scheduled a urinalysis, blood test, Kidney ultrasound and bladder ultrasound. All tests came back perfect and I was told both my kidneys and bladder were in perfect health. My urinalysis showed zero blood or proteins and my blood test was clean.
Just because you come back positive during a dip test doesn't necessarily mean there is something wrong.
However, it could be a sign of any number of things. It's best to get the follow up exams out of the way to ensure your safety. Possible causes are anything from a simple urinary infection to cancer. Don't jump to conclusions.
