In Fast PET, which component is included in its protocol?

• A. A Serum Sample
• B. No Serum Samples
• C. A Urine Sample Only
• D. No Blood Samples

Answer: (A)

The main concept being tested is that even in the shortened Fast PET protocol, a serum sample is collected to evaluate how quickly solutes move between blood and dialysate. By measuring plasma concentrations in serum at the test time and comparing them to dialysate concentrations, you can calculate the dialysate-to-plasma (D/P) ratio and classify peritoneal membrane transport characteristics efficiently. Without serum, there would be no plasma benchmark to interpret how fast solutes equilibrate, which undermines the purpose of PET. That’s why including a serum sample is the best fit. A urine sample alone wouldn’t provide the necessary plasma solute data, and saying there are no blood/serum samples would remove the essential reference point for interpreting transport.
