Abstract
A method of improving the accuracy and reproducibility of non-invasive measurements of a concentration of a constituent of interest carried in a body part has been developed. The method relies on elevating the body part during the measurement cycle so that the body part is maintained above the heart during the measurement cycle. Measurements of the constituent during an arterial pulse leads to improved intra-run and run-to-tun determinations.
