Which PET modality uses a daytime 4.25% solution and overnight 2.5% solution?

• A. Modified PET
• B. Kinetic PET
• C. Fast PET
• D. No PET

Answer: (A)

In PD, the Peritoneal Equilibrium Test (PET) can be performed with different protocols to reveal how the peritoneal membrane handles water and solutes under varying osmotic conditions. The Modified PET uses two dwells with different glucose concentrations to stress the membrane differently across the day and night. During the daytime, a higher glucose concentration of 4.25% creates a strong osmotic gradient to maximize ultrafiltration and show how well the membrane can sustain UF. Overnight, a lower concentration of 2.5% provides a gentler gradient to continue assessing solute transport without overwhelming UF, helping separate transport characteristics from UF capacity. This two-concentration, day-versus-night approach is what defines the Modified PET. Other named PET variants aren’t described with this specific day/night two-glucose protocol, and No PET would mean the test isn’t performed at all.
