January 2024—Ad Astra Diagnostics has received 510(k) clearance from the FDA for its QScout rapid-result hematology system. The analyzer provides point-of-care white blood cell counts and a neutrophil-to-lymphocyte ratio and differentiates the number and percent of five types of mature WBCs as well as immature granulocytes. To run the test, whole blood is added to a QScout rapid leukocyte differential test, which contains a dried reagent that stains cells. When the test is inserted in the QScout analyzer, an optical system takes images and an algorithm identifies the cells in real time. Results are displayed in about two minutes.
