Product Overview

Every Hematocrit counts because every donor counts. And that's why there's UltraCrit™.

Now you can get lab accuracy with a handheld device.

UltraCrit™ is the first and only hematocrit/hemoglobin device to use ultrasound technology. UltraCrit™ has shown an accuracy of <0.4 (when read in tenths), resulting in a decrease in both 'false deferrals' and 'false accepts'.

Just wick a drop of blood into the single-use cuvette and insert it into the device. The hematocrit is displayed automatically in about 30 seconds. It's that easy.
