Quick Study.

Let’s get right to the point.

No one has time to wait for answers. That’s why we are developing QScout RLD (Rapid Leukocyte Differential). It reports a white blood cell count and differential at patient-side in about 2 minutes from a drop of blood.* Results include immature infection-fighting cells some labs count manually.

News that counts.

Ad Astra Diagnostics files 510(k) for QScout hematology analyzer 

System purpose-built for point of care aims to democratize access to diagnostics, including rapid measures of infection

Ad Astra Diagnostics (AAD), developer of rapid diagnostic systems, today 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.

Forget the hassle.

QScout RLD requires no lengthy machine startup time or sample prep. No wet reagents that need to be changed or disposed. No pumps. Only a drop of blood. It goes from powered off to your first result in about 3 minutes. It’s easy to use with minimal training.


See the difference.

It’s an imaging-based system not prone to the challenges of flow cytometry or the Coulter Principle. Cells are examined directly by a trained computer using AI instead of indirect measures like light scatter or electrical resistance.

*QScout™ RLD is not yet cleared and not available for sale within the United States.
