Ad Astra Diagnostics (AAD), developer of rapid diagnostic systems, announced that it has submitted a 510(k) application to the U.S. Food and Drug Administration (FDA) for its QScout RLD rapid-result hematology system intended to report white blood cell count, neutrophil-to-lymphocyte ratio, and counts of six white blood cell types in fingerstick or venous blood.

QScout is the first hematology platform designed for simple, fast operation at point of care to provide measures of disease and infection including a ratio of two white blood cell types (neutrophil-to-lymphocyte ratio) and count of immature granulocytes. The technology was funded in part by a federal contract with the Biomedical Advanced Research and Development Authority’s (BARDA) Division of Research, Innovation and Ventures for the earlier detection of severe infection, including sepsis in prehospital settings. The contract supported the capability to count immature infection-fighting granulocytes, one of the earliest markers for sepsis. Sepsis, the body’s extreme response to infection, is a life-threatening medical emergency that happens when infection triggers a chain reaction throughout the body.

“Submitting a 510(k) application for the QScout system is a significant milestone for our team in the ongoing development of this potentially groundbreaking diagnostic platform and the growth of Ad Astra Diagnostics,” said Joy Parr Drach, AAD’s president & CEO. “We now look forward to working with the FDA to advance the regulatory review process towards a potential clearance of the system for use at point of care where faster results can improve health outcomes and in the lab where it can improve efficiency. Meanwhile, we will continue discussions with partners who can help reach those healthcare settings.”

To run the test, whole blood is added to a QScout RLD (rapid leukocyte differential) test, which contains a dried reagent that stains cells. When the test is inserted in the QScout Lab analyzer, an optical system takes images, and an algorithm identifies cells in real time. Results are displayed in about two minutes.

According to AAD’s chief scientific officer and co-founder, Rudy Rodriguez, “QScout RLD was designed as a quick, quantitative ‘scout’ for infection that is simple enough to operate yet robust enough to deliver reliable data patient-side. In doing so, QScout RLD offers the potential to democratize access to quality diagnostics, while providing healthcare professionals with a potentially life-saving tool.”
