Abstract: A method for measuring, adjusting and maintaining the level of blood volume in a patient is described. A blood volume expander composition includes, in combination, a standard unmodified protein, colloid or crystalloid and a fluorescently-labeled protein, colloid or crystalloid of approximately the same molecular weight. The use of blood volume expanders to measure, adjust and maintain the level of blood volume in a patient also is described.

Abstract: Methods of measurement of biometric indicators in a mammalian subject are described. Biometric indicators of interest include hematocrit, plasma volume, volume of distribution, and glomerular filtration rate. The methods are especially applicable to subjects with rapid blood loss and to subjects with unstable hematocrits. Hematocrit may be measured by administering an injectate with a dynamic fluorescent marker and a static fluorescent marker, or a single static marker with two fluorescent tags, into the vascular system of the subject, and monitoring the emission intensities of the markers or fluorescent tags over a period of time. Hematocrit may then be calculated using a calibrated spectrometric analyzer by determining the raw ratio of the markers at T0, calculating the apparent hematocrit, and applying a correction factor.

Abstract: Compositions and methods for increasing fluorescent signals generated by biomarkers are described. This serves to increase the accuracy of results when the biomarkers are used for the detection and diagnosis of physiological conditions, such as organ function and plasma volume.

Abstract: A method for measuring a glomerular filtration rate of a mammalian subject comprises a source of reporter and marker fluorescent molecules. The fluorescent molecules are introduced into the vascular system of the mammalian subject. Over a period of time, a measurement of the intensities of the reporter and marker fluorescent molecules is taken. A ratio is calculated to determine the glomerular filtration rate.
