This prototype tool calculates absolute and normalized Glomerular Filtration Rate (GFR).

Provide patient metrics and CPM measurements of the standard, blank and patient blood samples (including injection times). The tool creates a plasma curve plotting measurement time versus the calculated normalized plasma count rate %. The calculations use a variant of the Brøchner-Mortensen correction and the Haycock method for surface area calculation.



Supply your measurement data (CPM values for Background, Standard, then each blood sample time with time): Help
Help You can supply your raw data in two ways:
  1. Enter (or Paste) the raw data into the edit box. Use the same format as the example data (i.e. numbers separated by spaces). More...
  2. Select a data file on your computer and press Upload. Most raw data file formats are automatically recognised and processed. Formats not currently supported can be added very quickly. More...
After reviewing other analysis parameters press the Calculate button below to process your results.
