A new rapid urine test can tell doctors which antibiotic will effectively treat a urinary tract infection (UTI) in under six hours. This breakthrough, developed by scientists at the University of Reading, the University of Southampton, and Hampshire Hospitals NHS Foundation Trust, significantly cuts down the typical two-to-three-day wait for lab results. The innovative method aims to speed up treatment, reduce antibiotic resistance, and prevent severe complications like sepsis.[sciencedaily+4]
Faster, More Targeted Treatment
Current methods for diagnosing UTIs often involve culturing urine samples overnight to identify bacteria and determine antibiotic susceptibility. This process can take two to three days, delaying targeted treatment.During this waiting period, patients often receive broad-spectrum antibiotics, which may not be effective against their specific infection.This can prolong symptoms and contribute to the growing problem of antimicrobial resistance.[sciencedaily+7]
The new test bypasses the overnight culturing step entirely.It uses a cartridge containing small tubes pre-loaded with different antibiotics.Researchers dip this cartridge directly into a urine sample and then insert it into an instrument.The system then uses optical imaging to monitor bacterial growth in real time.If bacteria stop growing in a tube, that antibiotic is effective against the infection.If growth continues, the drug is not suitable.This direct-from-urine approach provides results in an average of 5.85 hours.[sciencedaily+21]
Dr. Oliver Hancox, Chief Executive Officer of Astratus Limited, the University of Reading spin-out company bringing the test to market, emphasized the importance of speed. "By the time the laboratory delivers the result under current methods, a patient may already have finished their antibiotics, or been given ones that do not work," Hancox said.He added, "Being able to tell a doctor the same day which antibiotic to use means the patient gets the right treatment sooner, reducing the risk of resistance developing and their infection turning into potentially lethal sepsis."[sciencedaily+12]
High Accuracy and Reliability
The research, funded by the National Institute for Health and Care Research (NIHR), was published on March 31, 2026, in the Journal of Antimicrobial Chemotherapy.The study evaluated 352 urine samples from patients suspected of having UTIs.The new test showed impressive accuracy, matching standard laboratory methods in 96.95% of cases for seven commonly used first-line antibiotics.[sciencedaily+14]
Researchers also conducted a second analysis on 90 duplicate samples.This study compared samples collected with and without a preservative (boric acid), which is often used to stabilize urine samples.The results showed a 98.75% agreement between the two sets, confirming that the preservative did not interfere with the test's accuracy.This is the first study to directly compare the impact of boric acid on a rapid direct-from-urine method.[sciencedaily+21]
Professor Mike Lewis, NIHR Scientific Director for Innovation, highlighted the broader implications. "This NIHR-funded research not only has the potential to deliver quicker, more effective treatments to patients suffering with UTIs – but also tackles the broader challenge of antimicrobial resistance," Lewis said. He described the rapid urine test as "a fantastic example of the real-world solutions to AMR that the government committed to developing in its 10-Year Health Plan."[sciencedaily+3]
Addressing a Widespread Health Issue
Urinary tract infections are a common health concern, leading to millions of doctor visits each year. In England alone, UTIs have resulted in more than 800,000 hospital admissions over the past five years. Asignificant challenge is the rising prevalence of antibiotic-resistant bacteria. Around one in four urine samples tested in NHS laboratories contain bacteria that are resistant to commonly used antibiotics. This makes it crucial to identify the correct antibiotic quickly.[familymedicineaustin+7]
Misdiagnosing a UTI or prescribing an ineffective antibiotic can have serious consequences. It can lead to prolonged suffering, more severe infections, and increased healthcare costs. In some cases, UTIs can even progress to life-threatening sepsis. The ability to provide targeted treatment on the same day can significantly improve patient outcomes and reduce these risks.[cidrap+11]
Astratus Limited, the University of Reading spin-out company, was established in November 2024 to bring this test to market. The company supports a "One Health Approach" to reduce antimicrobial resistance, aiming to ensure clinicians can prescribe the right drug for the infection, thereby improving outcomes and saving lives. This new diagnostic tool represents a significant step forward in combating antibiotic resistance and enhancing patient care for UTIs.[clpmag+10]
