How does a UTI Test Strip Work?

There are many different types of urine test strips and many of these are used to detect signs of a urinary tract infection, often shortened to UTI. If someone has developed a UTI, there are several signs and symptoms that they might notice. Those who have a UTI often run a fever, have abdominal pain, and complain that their urine smells a bit odd. They might also notice that their urine is cloudy and that it burns when they use the bathroom. With the help of a high-quality urine test strip, the diagnosis of a UTI can be confirmed and treatment can start. What are some of the substances that a UTI test strip can find?

Nitrites in the Urine

One of the most common substances that a UTI test strip will look for is nitrites. There are certain bacteria that metabolize the body’s nutrients and produce nitrites as a byproduct. Therefore, if nitrites are detected on the urine test strip, there is a good chance that the individual has developed a UTI. Not all bacteria produce nitrites; however, many of the common causes of UTIs will develop nitrites during their metabolic process.

The Presence of Leukocyte Esterase

Another common substance that is present in the urine during a UTI is called leukocyte esterase. This is highly specific for the presence of a UTI. Leukocyte esterase is an enzyme that is produced by white blood cells. If this enzyme is present in the urine, it means that white blood cells are in the urine. If the white blood cells are present in the urine, they are probably fighting an infection. Because of this, leukocyte esterase (LE) is often used to diagnose a urinary tract infection.

Using a High-Quality UTI Test Strip

UTI test strips can detect numerous signs of a urinary tract infection with a simple dip test. Because they are both reliable an inexpensive, many people rely on these strips to identify urinary tract infections. Once the infection has been diagnosed, antibiotic treatment can begin to clear the bacteria from the urinary tract. With proper treatment, most people will make a full recovery.
