Microscopic Hematuria Testing
Microscopic hematuria and testing for causes of the blood in urine is a necessary step in the evaluation of your urinary symptoms. A urine dipstick placed in your urine sample changes color depending on the levels of substances in your urine. A urinalysis test can show the levels of sugar, ketones (fatty acids), red blood cells in the urine, and protein in the urine. If you have high levels of protein, you may have a condition called proteinuria (also known as urine albumin). Too much protein in the urine could mean you have diabetes, high blood pressure, or kidney disease.
Microscopic hematuria and the testing for it will depend on your symptoms. If you’re displaying symptoms of a urine infection (such as cloudy urine, frequent urination, abdominal pain, or burning urination) our doctors may also order a nitrite test and urine culture to test for bacteria. Bacteriuria is when there are bacteria found in the urine. Doctors may notice high levels of white blood cells in the urine or pus cells, clear signs that your body is trying to fight off urine infections.
Some people test their urine at home using the Chemstrip, Multistix 10, or Clinistix dipstick test for the urine. Ketostix can also keep track of the amount of ketones in your urine; ketones are made when fat breaks down to give you energy instead of insulin. These strong acids in excess are harmful and when a ketone test finds them in your urine, it may mean that you have a form of diabetes.
If you are experiencing gross hematuria, you may get varying results. Blood from the kidneys from kidney cancer or kidney disease may also enter the urine during testing. Blood in urine for men may indicate that you have a problem with the prostate, while blood in urine from a female may give false results to urinalysis testing if the test is done during her menstrual cycle.
Microscopic hematuria and testing can tell us a lot about what urinary problem you’re experiencing. If you receive a negative culture, and you are still experiencing symptoms, you may need to repeat the test again in a few weeks to see if any of the results have changed. Our doctors may need to order a urine and stool test to make a proper urine diagnosis. A urine microscopy may also be necessary to have the cells examined in much more detail under a microscope. It’s important for our urologists to order any and all necessary tests in order to determine what the actual cause of the blood in urine is, so that the treatment can be properly targeted.
