PET CALCULATIONS10
D/P CREATININE =
*Corrected Dialysate Creatinine Concentration at 0-hr, 2-hr, 4-hr Dwell
Plasma Creatinine Concentration at 2-hr Dwell
D/D0 GLUCOSE =
Dialysate Glucose Concentration at 2-hr and 4-hr Dwell
Dialysate Glucose Concentration at 0-hr Dwell
*If nonenzymatic method (i.e. picric acid assay) is used for analysis of creatinine, be sure to use correction factor to accurately estimate creatinine value.
D/P Creatinine
D/D0 Glucose
| Membrane Transport Type | 4-hour D/P Creatinine |
|---|---|
| HIGH | 0.82 - 1.03 |
| HIGH-AVERAGE | 0.65 - 0.81 |
| LOW-AVERAGE | 0.50 - 0.64 |
| LOW | 0.34 - 0.49 |
If discordance in D/P creatinine and D/D0 glucose is noted, it is recommended to repeat the PET. Clinical assessment must be taken into account if results remain discordant.10
