Mrs. Spike has been diagnosed with COVID-19 pneumonia. She is 72 years old, but luckily has a mild infection and has self-isolated at home. A few days afterwards her fever rises, and she starts having urinary symptoms (burning when urinating with left flank pain). Is the fever the result of a viral or a bacterial infection? A complete blood count would be extremely informative. With the aid of the RevDx system she would be able to undergo a complete blood count without any contact with healthcare personnel. In the future, urine analysis would be added to the system, enabling a more complete, quick, diagnostic procedure without the patient having to leave her living room.
