When is a dialyzer sensitivity reaction usually seen?

• A. After several hours
• B. At the end of treatment
• C. In the first half-hour of treatment
• D. Next day

Answer: (C)

Dialyzer sensitivity reactions are immediate responses to the dialyzer exposure and occur soon after the treatment starts. The reaction is driven by the membrane or residual sterilants and involves rapid immune/complement-mediated changes, so it typically appears within the first 30 minutes of the session. That makes the early part of the treatment the point where these reactions are most likely to be seen. Reactions that show up later, at the end of treatment, or the next day don’t fit the usual pattern of a dialyzer sensitivity reaction and suggest other causes. If such a reaction occurs, it’s treated as an urgent event requiring stopping the dialysis circuit and medical assessment.
