    Abstract: The present invention is related generally to measurement of body fluid volumes in an animal subject. The body fluid volumes of interest include extracellular fluid volume (ECFV), total vascular plasma volume (TVPV) and interstitial fluid volume (IFV). The methods are especially beneficial for subjects suffering from renal failure and particularly those undergoing renal dialysis. ECFV can be measured by administering a first molecule which is non-metabolized and permeable to vessel walls of the vascular system wherein the first molecule is distributed within the total vascular space as well as the interstitial space. TVPV can be measured by administering a second molecule which is non-metabolized and impermeable to vessel walls of the vascular system wherein the second molecule is distributed within only the vascular space. IFV can then be calculated using the equation IFV=ECFV−TVPV.

    Abstract translation: 本发明一般涉及动物受试者体液体积的测量。 感兴趣的体液体积包括细胞外液体积（ECFV），总血管血浆体积（TVPV）和间质液体体积（IFV）。 这些方法对于患有肾功能衰竭的受试者尤其是肾透析患者特别有益。 可以通过施用第一分子来测量ECFV，所述第一分子是血管系统的血管壁的非代谢和可渗透的，其中第一分子分布在总血管空间以及间质空间内。 TVPV可以通过施用第二分子来测量，所述第二分子是非代谢的并且不渗透血管系统的血管壁，其中第二分子仅分布在血管空间内。 然后可以使用IFV = ECFV-TVPV等式计算IFV。

    Abstract: A method for measuring a glomerular filtration rate in a mammalian kidney comprises a source of reporter and marker fluorescent molecules. The fluorescent molecules are introduced into the blood stream of a 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 health of the subject's kidney. This method measures volume of plasma distribution based on a fluorescence of a marker molecule relative to a fluorescence of a reporter molecule.
