Urinalysis Reagent Test Strips Provide Medical Information Quickly And Accurately

By Stacey Burt


Although they may seem like another technological wonder of the digital age, the small sticks or ribbons made of paper or plastic used to reveal abnormal changes in body chemistry originated over one hundred years ago. As early as the 1880s pharmacists and medical personnel began searching for new analytic methods superior to the cumbersome processes available at the time. The earliest types of urinalysis reagent test strips appeared in 1883, and revolutionized testing and diagnostics.

A century of development and practical field use has made them integral in detecting abnormal kidney output. They are used to measure the progress and scope of diabetes mellitus, an epidemic today due to current dietary preferences and inactive lifestyles. Other liver and blood indicators of disease are commonly revealed using this process, and detecting urinary tract infections has become quick and simple.

They are manufactured without using test-altering glues to bind individual pads and layers together. They avoid results caused by heavy exercise, which can produce trace amounts of blood in the urine, or the presence of high levels of ascorbic acid, associated with Vitamin C. Special controls eliminate false readings, and additional non-reactive substances also keep information accurate.

Individual pads change color when specific chemical products are present. They not only detect blood, but can also determine pH levels. They display evidence of potential disease indicators such as glucose levels, nitrites, leukocytes, ketones, and others. Although these substances can be detected using more traditional methods, small strips provide obvious advantages to technicians, doctors, and patients.

Accurate results can be read in 60 seconds, appearing as specific changes in color bands. Individual strips are purposely designed for upside-down reading, a feature appreciated by lab technicians dealing with multiple specimens. Specific colors represent individual chemicals, and can be easily compared side-by-side with change-resistant control colors printed on the packaging. Developing hues appear rapidly and evenly.

This method is not only specific, simple to interpret, and easy to use, but is also cost-effective. The main purpose of these devices is not to specifically diagnose a particular disease, but rather to accurately detect metabolic indicators common to several ailments. Any positive reading must be followed by more specific examinations. When individual self-monitoring is necessary, patients appreciate their ease of use and ready availability.

With the guidance of a physician, many high-risk diabetic patients are able to accurately check personal levels of glucose and ketones, both of which are metabolic products indicating change. People suffering from hypertension with the possibility of kidney damage can easily check their own day-to-day function. Those experiencing repeated urinary tract infections find self-detection a good way to limit duration and speed recovery.

Due to widespread availability in most drugstores, there is an increased chance of that individuals may misinterpret the results, and mistakenly assume they have a serious illness. To avoid this emotionally stressful situation, it is important to see a doctor immediately if readings are unexpectedly positive. While discovering a medical problem early is helpful, finding long-lasting solutions to serious issues is the most important goal.
