Urinalysis Quality Control at the Point-of-Care !


The goal of any clinical diagnostic test procedure is to provide critical information in a timely manner so that appropriate actions may be taken, ultimately improving patient outcomes. Point-of-care testing (POCT) is a term that has come to describe a multitude of rapid medical tests that can be performed at or near the site of patient care. The most compelling benefit of these tests is that, as opposed to having to wait hours or days for results to arrive from an outside laboratory, clinicians can obtain the results immediately, allowing for clinical management decisions to be made while the patient is still at the care facility. While the implementation of rapid diagnostic tests dates back to ancient history (sweet-tasting urine was once commonly used to diagnose diabetes mellitus), it was not until the 1950s that these rapid diagnostic methods gained any real predictive value. Today, the popularity and demand for POCT are increasing rapidly. TriMark Publications estimates that the global market for POCT was $14.5 billion in 2016, and is expected to grow by seven percent over the next five years.




Urinalysis dipsticks at the point-of-care:


Urinalysis using multi-analyte dipsticks is a point-of-care test performed at any hospital, clinical laboratory, doctor’s office, health clinic, and nursing facility. Various iterations of these tests have existed for decades, and they continue to be among the most commonly performed tests of any kind. Urinalysis dipsticks contain discrete reagent pads to semi-quantitatively test for the presence of bilirubin, blood, creatinine, glucose, ketones, leukocytes, nitrite, pH, protein, specific gravity, and urobilinogen in a urine sample.
