Unraveling the Mystery: How Doctors Detect Blood in Your Urine

The Dipstick Test: Your First Line of Defense

The urine dipstick test is often the first step in detecting hematuria. It's a simple, quick test that can be done in a doctor's office. A strip of paper treated with chemicals is dipped into a urine sample. If blood is present, the strip changes color. While highly sensitive, this test can sometimes give false positives, so further testing is usually needed to confirm the results.

Under the Microscope: A Closer Look

If the dipstick test is positive, the next step is usually a microscopic examination of the urine. A small amount of urine is spun in a centrifuge to concentrate any cells present. Then, a trained professional examines the sample under a microscope. They're looking for red blood cells, but they can also spot other important clues like bacteria or crystals that might indicate the cause of the hematuria.

Advanced Imaging: Seeing the Big Picture

For a more comprehensive view, doctors may order imaging tests. CT urography is often the preferred method. It uses X-rays to create detailed 3D images of your entire urinary system. Ultrasound is another option, especially for pregnant patients. It uses sound waves to create images and doesn't involve radiation. In some cases, MRI might be used, particularly if CT isn't suitable.
