Dual Reporting Calculations – HbA
The dual reporting calculations convert the NGSP and mono-S percentages to
IFCC mmol/mol. The source for the following calculations is

Glomerular Filtration Rate Calculation

The system calculates the values for Glomerular Filtration Rate (GFR) by
using the following calculation. The source for the calculation is the National
Kidney Foundation publication of 1999 MDRD study equation.
GFR = 186 x (plasma creatinine mg/dL)
(0.742 if female patient) x (1.210 if African-American patient)

Printed Reports

This section shows the contents of several of the printed reports that you can
select. The Patient Test Report and the System Settings Report have both a
long and a short format. These tables show the contents of each:
• Patient Test Report Contents‚ page 183
• Patient Trend Graph Report Contents‚ page 185 (Requires external

• Control Test Report‚ page 186
• System Settings Report‚ page 188

Patient Test Report Contents

When an HbA or Microalbumin/Creatinine patient test completes, the system
1c
displays the results on the screen. If you have enabled printing, the system
can also print the results on the onboard or external printer, depending on the
system settings. The short-form printout contains less data but prints faster.
The displayed patient test results are the same as for the long-form printed
results. The following table summarizes the information that the system prints
for patient tests.
