Urine Occult Blood

A healthy result should fall into the range 0 - 0.001 mg/d.

Urinalysis refers to a series of tests that can be run to assess the chemical quality of urine. Typically, this is done by dipping a strip into the urine sample, and chemical reactions change the color of the pads. Occult blood is blood that cannot be seen without a microscope. Normal urine doesn’t contain red blood cells, except females’ urine during menstruation. Blood in the urine, called hematuria, is not a normal finding, but it is not uncommon and not necessarily a cause for alarm. Your healthcare professional will investigate further to try to determine the source and underlying cause of the blood. There are some risk factors that can put you at risk for hematuria such as:

            -Age (men older than 50)

            -Sex (women with urinary tract infections, men with kidney stones)

            -Recent infection (particularly of the kidneys in children)         

            -Family history

            -Certain medications (aspirin or penicillin)

            -Strenuous exercise
