Brief Summary
The NBM-200 is a portable Hemoglobin and oximetry monitor, based on occlusion spectroscopy technology, for non-invasive spot checking of hemoglobin (Hb), estimated Hematocrit (Hct), SpO2 and pulse rate. The NBM-200 includes a reusable ring-shaped sensor probe that fits on the patient's finger, and a portable desktop monitor that calculates and displays the measurement result. The sensor probe consists of a multi-wavelength optical measuring system and inflatable cuff employing pneumatic tissue manipulation. Blood flow in the finger can be briefly occluded and the resulting changes in its optical behavior are analyzed to provide accurate measurements of Hb.

Comparison
OTHERComparison study: The participants (at least 300) will be tested once with each of the 3 devices. First, a measurement with the NBM-200 will be performed according to the user manual. The best finger to use, in order of preference: 1) right thumb 2) left thumb 3) right index 4) left index. The POC capillary test will follow the NBM-200 test, and the venous test will be performed last. A venous blood sample will be obtained from all participants in the comparison study, even if a subject is designated to donate and is deferred from donation because of low hemoglobin.
Precision A & B
OTHERPrecision study: 1. At least 12 subjects will be tested 6 consecutive times with the NBM-200, on either the right or left thumb, and then 6 times with the capillary device (with a separate finger-prick for each test). 2. At least 3 males and 3 females at 2 study sites (total of 12), preferably with hemoglobin levels close to the cutoff levels of 12.5 g/dL for females and 13 g/dL for males. Each subject will be tested on each of their right and left thumbs and indices (4 fingers) using at least two operators and two NBM-200 instruments on each finger. A laboratory test with venous blood is not required for participants in the precision study.
