Blood in Urine (Hematuria)

Blood in urine - known medically as hematuria - is usually not a reason for major alarm.
Because blood in urine can be a sign of a serious medical condition, however, it shouldn't be ignored. If you have some uncomfortable of your blood urine, you’d better have a test in hospital , such as hematology analyzer, urine chemistry analyzer. All cases of hematuria should be evaluated by a doctor who can order tests to confirm or rule out an underlying cause.
There is no specific treatment for hematuria since it's a symptom and not a specific condition. Instead, treatment is aimed at the underlying cause if one can be found. In many cases, no treatment is necessary.
Where Blood in Urine Might Come From
Blood in urine can come from the kidneys, where urine is made. It also can come from other structures in the urinary tract, such as:
l         Ureters  (the tubes from the kidneys to the bladder).
l         Bladder  (where urine is stored). 
l         Urethra  (the tube from the bladder to the outside of the body).
Symptoms That May Accompany Hematuria
If there is blood in urine, the symptom is obvious. Instead of its normal pale yellow color, your urine may be pink, red, brownish-red, or tea-colored. This is what doctors call gross hematuria.
Sometimes, blood in urine is not visible to the naked eye and the presence of red blood cells can only be detected by the lab. This is what doctors call microscopic hematuria. It's usually only discovered when a urine sample is tested with a dipstick and the results are confirmed with a microscopic examination.
Hematuria may occur without any other symptoms. Some underlying causes, however, are associated with additional symptoms that can be moderate to severe.
