Red urine is not always blood.

Red or pink urine
Despite its alarming appearance, red urine isn't necessarily serious. Causes include:

* Blood. The presence of red blood cells is the main reason urine turns red. Usually, bleeding isn't severe and occurs without other signs or symptoms. Factors that can cause urinary blood, known medically as hematuria, range from strenuous exercise, urinary tract infections and an enlarged prostate to kidney or bladder stones, kidney disease, and, occasionally, kidney cancer or bladder cancer.
* Foods. Beets, blackberries and mom's rhubarb pie can turn urine red or pink.
* Medications. Certain laxatives — Ex-lax is an example — can cause red urine. Prescription drugs that have the same effect include antipsychotics such as chlorpromazine (Thorazine) and thioridazine and the anesthetic propofol (Diprivan).
* Toxins. Chronic lead or mercury poisoning can cause urine to turn red. This may be the result of high levels of excreted porphyrins, the same pigments that discolor the urine of people who have porphyria.
