During dialyzer reprocessing, the blood compartment is tested to determine which parameter?

• A. Hematocrit
• B. Total cell volume
• C. Dialyzer priming volume
• D. Platelet count

Answer: (B)

The test focuses on the amount of space the dialyzer’s blood path can hold, which is the total cell volume. This parameter reflects the dialyzer’s internal blood compartment capacity and is checked during reprocessing to confirm the device is intact and can be properly primed for use. Knowing the total cell volume helps ensure accurate priming and that no air pockets remain in the blood path, contributing to patient safety during subsequent treatments. It’s a property of the dialyzer itself, not a patient characteristic, which is why hematocrit (a patient value) and platelet count aren’t relevant in this context. The dialyzer priming volume refers to how much saline is needed to fill the device initially, which is a separate measure from the blood compartment’s volume.
