Worksheet instructions and an example can be downloaded here: link
This program is designed to calculate GFR measurements from blood samples taken from patient after administration of a low dose (~20 uCi) of I-125.
In this sheet, full curve characterization of plasma activity curves is calculated using biexponential modelling. In addition, GFR calculations are derived using single compartment methods and single time point methods, for comparison.
Our GFR worksheet is modelled after the protocols and calculations described in:
