it could be benign idiopathic hematuria or a urinary tract infection
Lots of reasons for the urine to be red in color, and the answer is to see your doctor for testing.
The condition you described is called Hematuria. If the blood is visible, this is called macroscopic hematuria, if the blood is discovered via a urine test in the lab, it is called microscopic hematuria. I would bring this to your PCP, conditions to look for include infection to the urinary tract, stones, or some type of illness that may have affected the actual kidney structure. I would start with a urine dipstick and microscopic analysis if this was not done. A referral to a urologist or a kidney specialist may be warranted if the work-up revealed a definite condition.
Wishing you the best.
The most common cause of blood in your urine at your age is a urinary tract infection (bladder infection). If you have been sexually active, it would be wise to have testing for sexually transmitted infections.
This could be normal depending on how much blood, other causes, trauma, stones, renal cyst, single or polycystic, and nephritis if associated with proteinuria.
Hello.

There are many causes for blood in the urine. There are also some other substances- named pigments- that can cause the urine to appear as if there may be blood; for example myoglobin- from muscle breakdown- and bilirubin- from liver or bile disorders. Even true blood in the urine, associated with no symptoms can be caused by a variety of problems in the upper or lower urinary systems, from kidney inflammatory diseases to simple urinary tract infection. The very first step would be to confirm hematuria (blood in the urine) by urinalysis, with a microscopic analysis to differentiate between renal vs non-renal causes of hematuria.
