The AAMI standard for endotoxin levels in conventional dialysate is which of the following?

The AAMI standard for endotoxin levels in conventional dialysate is which of the following?

• A. less than two (2) EU/mL
• B. less than five (5) EU/mL
• C. less than ten (10) EU/mL
• D. less than one (1) EU/mL

Answer: (A)

Endotoxins are pyrogens from Gram-negative bacteria that can trigger fever and inflammatory responses when dialysate contacts the patient’s blood during dialysis. Because the dialysate is in direct contact with blood across the dialysis membrane, the AAMI standard keeps the endotoxin level in conventional dialysate very low to minimize these reactions. This conventional dialysate limit is a small amount per milliliter—low enough to reduce risk but still achievable with proper water treatment. Ultrapure dialysate uses a much stricter endotoxin limit, reflecting even greater safety requirements for that product. Endotoxin levels are measured with the Limulus amebocyte lysate assay to ensure they stay within the specified limit.
