Video: The United States Has Developed A Rapid Test To Identify The Risk Of Kidney Stones
The United States has developed a rapid test to identify the risk of kidney stones
A 30-minute urinalysis not only measures the level of substances that contribute to the appearance of kidney stones, but also controls and prevents this process.
Kidney stones are accumulations of minerals and salts that can cause severe pain and a blockage in the urinary system. According to American doctors, 19% of men and 9% of women are susceptible to kidney stones. In this case, the frequency of relapses reaches 60-80%, therefore, patients prone to diseases of the urinary tract need regular prevention. Today, however, urinalysis to identify substances that contribute to the formation of kidney stones is difficult and time-consuming, which is why it is underutilized in clinical practice. Patients need to collect a certain amount of urine within 24 hours and send it to laboratories, where an analysis is carried out using expensive equipment, the results of which will appear no earlier than a week later.As a result, this type of research is insufficiently used in clinical practice.
Researchers from Pennsylvania and Stanford University have created a rapid SLIPS-LAB test that detects levels of these substances in just 30 minutes. The scientists published the results of their work in the journal Science Advances.
According to them, express analysis does not require special equipment and can be carried out in the doctor's office and even at home. To create the test, the researchers developed the SLIPS-LAB biomimetic detection system.
According to the researchers, the device was inspired by the carnivorous plant nepentes, which are shaped like a jug filled with digestive fluid. The border of these plants has a slippery porous surface that draws the insect into the jug. SLIPS-LAB allows reagent and urine droplets to easily move over the smooth surface of the plastic channel to allow fluid to enter the test device. The small pressure drop due to surface tension sets the droplets in motion, which allows them to bond with the reagents. The analysis results can be assessed using a mobile phone camera.
“The low cost, speed, and ease of use of SLIPS-LAB can help clinicians improve the clinical management of urolithiasis,” they write.
