"Decompression Artifact" Fingertip Spiral Is Used For The Point-Of-Care Diagnosis Of Urinary Tract infection

2020-05-21 来源:转载自第三方

In the in vitro diagnostic industry, point-of-care testing (POCT) has many advantages, such as ease of use, high efficiency, high accuracy, and high accuracy regardless of time and location. And its comprehensive cost is generally low, so it has developed rapidly in recent years.

Recently, a research paper published by "Nature Biomedical Engineering" showed that Korean scientists describe a custom-made fidget spinner  that can be used for immediate detection of urinary tract infection, with fast, convenient, simple and accurate results.

The fidget spinner rapidly concentrates pathogens in 1-ml samples of undiluted urine by more than 100-fold for the on-device colorimetric detection of bacterial load and pathogen identification. In Tiruchirappalli, India, the device enabled the on-site detection of infection with the naked eye within 50 min in urine samples from 39 patients suspected of having a urinary tract infection.

The researchers also showed that, in 30 clinical samples of urinary tract infection, the device can be used to perform an antimicrobial susceptibility test for the antimicrobial drugs ciprofloxacin and cefazolin within 120 min. The fidget spinner could be used in low-resource settings as an inexpensive handheld point-of-care device for the rapid concentration and detection of pathogens in urine samples.

The emergence of this device is the development of POCT technology. In the future, with the continuous emergence of new technologies and new applications, POCT will achieve faster and better development.
