a. BLOOD IN THE URINE

The presence of blood in the urine can often be credited to urinary infection, kidney stones, or other health issues. However, the mere appearance of blood in your urine should already cause alarm, and prompt one to have it checked and tested.

Blood in the urine can either be seen visibly or only during urine examination (microscopic hematuria). In some cases, it can be a symptom of kidney cancer or of the bladder. In general, any episode of blood found in the urine should be further examined.
