UtraCrit handheld hematocrit for blood donor screening
UltraCrit hematocrit for blood donor screening

UltraCrit: A high-accuracy hematocrit measurement device for blood donor screening.

UltraCrit is the first and only hematocrit/hemoglobin device to use ultrasound technology. UltraCrit has shown an accuracy of ≤0.4% Hct, 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.
