What is this test?
This is a patient-reported symptom screen that asks whether you noticed blood in your urine or stool during the past 7 days. It is not a laboratory measurement and does not identify the cause of the bleeding.
Why might I need this test?
This information may help a healthcare professional decide whether further evaluation is needed. Blood can come from the urinary tract, digestive tract, or another nearby source, and the location and timing of symptoms can be important.
How is the test performed?
You answer whether blood was visible in urine or stool and may be asked when it started, how often it occurred, and whether you also have pain, weakness, dizziness, or other symptoms. Your clinician may recommend urine, stool, imaging, or other tests based on the response.
How do I prepare for the test?
No special preparation is needed for this symptom question. Before speaking with a clinician, note whether the blood was visible, any changes in bowel or urination habits, and other symptoms. Bring a current medication list, including blood thinners and over-the-counter products.
Reference range
Adult: 10-40 U/LN/A
No special preparation required. Avoid fatty meals before the test if possible.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Blood in the urine may result from infection, stones, kidney or bladder conditions, or other urinary problems. Blood in the stool can be associated with irritation, inflammation, polyps, or other digestive conditions; a stool test may be needed to detect blood that is not visible.
Short name
Blood in urine or stool, past 7 days
