Scientists at the Baltic Biomaterials Excellence Center in Latvia are pioneering a new method for diagnosing sepsis in newborns, which is a critical condition that can result in severe health complications. This innovative approach is being developed with national support and aims to reduce the discomfort associated with traditional blood sample testing by utilizing urine instead. The method is particularly important for premature infants who are at a higher risk of developing sepsis, also known as blood poisoning, which can be exacerbated by the standard practice of drawing blood for diagnostic purposes.

Leading researcher Kristaps Kļaviņš highlighted that the idea for this method originated from pediatricians at a children's hospital who encounter sepsis cases regularly. Current diagnostic procedures involve drawing up to three milliliters of blood, which can be a significant volume for a very small infant weighing as little as 900 grams. By shifting to a urine-based test, the researchers hope to alleviate the pain and stress often associated with blood collection in vulnerable newborns, making it a more child-friendly solution.

The research team, including assistant researcher Henriks Dundurs, is currently validating the test with urine samples from around 100 infants, looking for specific biomarkers that indicate the presence of sepsis. The preliminary findings have identified changes in three particular substances in the urine of those diagnosed with sepsis, prompting further studies to ensure the reliability and consistency of this new diagnostic method. If successful, this could revolutionize the approach to diagnosing sepsis in newborns, significantly improving patient care and outcomes in this vulnerable population.
