Why This Test Might Be Ordered

Your healthcare provider may recommend this test if you have symptoms like frequent urination, blood in urine, or signs of kidney issues. It can also be part of routine screening for certain conditions or after exposure to substances that may affect hemoglobin levels.

What to Expect During the Test

You’ll likely collect a urine sample at home or in a lab. The test involves a simple urine sample, often done in the morning for consistency. No special preparation is usually needed, but follow your provider’s instructions carefully.

Possible Causes of Positive Results

Hemoglobin in urine can come from conditions like hemolytic anemia (where red blood cells break down), kidney diseases, or certain medications. It can also appear after trauma or exercise that damages blood vessels.

When to Follow Up

If your test results are abnormal, your provider will discuss next steps, which may include additional tests, lifestyle changes, or monitoring. Follow their guidance closely.
