The small devices made of specially processed plastics or paper commonly used today to detect the presence of unusual chemicals in the urine are not a product of the digital age, but first appeared well over a century ago. Due to the cumbersome, time-consuming processes then available, doctors and pharmacists were actively searching for a better method of analysis as early as the 1880s. Prototype urinalysis reagent test strips were revealed in 1883, revolutionizing the process.
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.
Individual units contain layers and filter pads free from chemical glues that may alter results. While excess exercise or consumption of large amounts of ascorbic acid, or vitamin C, just prior to a test may distort the readings, reagent ribbons are specifically designed to avoid that problem. Special materials help prevent false information, and other non-reactive protections help ensure accuracy.
Each pad is designed to identify a specific chemical by changing to a different color after exposure. They can determine if blood is present, and accurately measure pH balance. They are able to detect leukocytes, glucose, ketones, nitrites, and other products of metabolism. Although these can be also measured using other methods, strips are preferred by laboratory workers, doctors, and especially patients.
They produce highly accurate results within one minute, in the form of specific color displays. Strips are designed for use upside down in order to prevent hand contact, a feature especially useful for technicians. Specific colors representing individual chemicals can be easily compared to the fade-resistant tones printed on the packaging vials. Color development is uniform and even.
In addition to being fast and accurate, the process is also cost-effective. Its main purpose is not to make a specific diagnosis, but rather to see which metabolic indicators of trouble appear, and whether or not they indicate disease. For full confirmation, testing must followed by an examination. If a doctor requests individual monitoring at home, patients appreciate the small size and simple instructions.
Patients at high risk for diabetes complications can track their own levels of glucose and ketones, both of which indicate internal changes. People currently attempting to avoid kidney damage resulting from hypertension use them to monitor daily progress. Common, recurring urinary tract infections can be detected without a trip to the doctor, and self-testing is becoming an increasingly popular choice.
Although test kits are sold in most pharmacies, there is the potential danger that specific results can be misinterpreted by patients, causing some to assume they have a condition or diseases that is not actually present, and sometimes leading to unnecessary emotional stress. If a test produces questionable results, the next step is to see a physician who will be able to present a more complete diagnosis.
