According to wikipedia…
In medicine, hematuria, or haematuria, is the presence of red blood cells (erythrocytes) in the urine. It may be idiopathic and/or benign, or it can be a sign that there is a kidney stone or a tumor in the urinary tract (kidneys, ureters, urinary bladder, prostate, and urethra), ranging from trivial to lethal. If white blood cells are found in addition to red blood cells, then it is a signal of urinary tract infection.
Occasionally “hemoglobinuria” is used synonymously, although more precisely it refers only to hemoglobin in the urine.
So there you go, the blood present in your urine is either trivial or lethal. I’m not sure I can be any more conclusive than that….get medical advice.
Or if you’re a gambling man…you could assume its trivial and ignore it.
PS, if you do take a gamble and you’re wrong…can I have your bikes?
