Brief summary
In this study, the accuracy of a noninvasive hemoglobin sensor(s) will be assessed by comparison to hemoglobin measurements from a laboratory hematology analyzer. Blood samples are collected from healthy volunteers who are enrolled in either a blood draw procedure or a hemodilution procedure wherein blood is repeatedly sampled as the concentration of hemoglobin is reduced in a controlled manner by administering fluids intravenously.
