Abstract
A computer-based method for automatically determining total body albumin of a living being based on the calculated intravascular albumin, the calculated observed ratio of amount of albumin in the intravascular system to amount of albumin in the extravascular system at the first time, and the baseline of expected ratio of amount of albumin in the intravascular system to amount of albumin in the extravascular system at the first time.
Claims18
An automated blood analyzer that analyzes blood of a living being, comprising:
- means for calculating a set of data points representing blood volume of the living being at one or more points in time after the living being is injected with radio-labeled albumin based on detected counts of the radio-labeled albumin at the one or more points in time;
- means for performing a first regression analysis on the set of data points using all of the one or more data points and for performing one or more second regression analyses on the set of data points with each second regression analysis calculated with a different data point removed, each of the first and second regression analyses comprising calculation of r-squared, residual standard error and slope values;
- and
- means for selecting based on the calculated r-squared, residual standard error and slope values of the first and second regression analyses which of the first and second regression analyses to use in further analysis of the blood of the living being.
A computer-based method for automatically analyzing blood of a living being comprising the steps of:
- calculating, using one or more processors, a set of data points representing blood volume of the living being at one or more points in time after the living being is injected with radio-labeled albumin based on detected counts of the radio-labeled albumin at the one or more points in time;
- performing, using one or more processors, a first regression analysis on the set of data points using all of the one or more data points and one or more second regression analyses on the set of data points with each second regression analysis calculated with a different data point removed, each of the first and second regression analyses comprising calculation of r-squared, residual standard error and slope values;
- and
- selecting, using one or more processors, based on the calculated r-squared, residual standard error and slope values of the first and second regression analyses which of the first and second regression analyses to use in further analysis of the blood of the living being.
A system for automatically determining total body albumin of a living being, comprising:
- one or more data processing apparatus;
- and
- a computer-readable medium coupled to the one or more data processing apparatus having instructions stored thereon which, when executed by the one or more data processing apparatus, cause the one or more data processing apparatus to perform a method comprising:
- calculating a set of data points representing blood volume of the living being at one or more points in time after the living being is injected with radio-labeled albumin based on detected counts of the radio-labeled albumin at the one or more points in time;
- performing a first regression analysis on the set of data points using all of the one or more data points and one or more second regression analyses on the set of data points with each second regression analysis calculated with a different data point removed, each of the first and second regression analyses comprising calculation of r-squared, residual standard error and slope values;
- and
- selecting based on the calculated r-squared, residual standard error and slope values of the first and second regression analyses which of the first and second regression analyses to use in further analysis of the blood of the living being.
