Abbreviations & Footnotes

OPA ortho-phthalaldehyde (FDA cleared as a high-level disinfectant, included for comparison to other chemical agents used for high-level disinfection)

AER Automated Endoscope Reprocessor

MEC minimum effective concentration is the lowest concentration of active ingredients at which the product is still effective

1 per cycle cost profile considers cost of the processing solution (suggested list price to healthcare facilities in August 2001) and assumes maximum use life (e.g., 21 days for hydrogen peroxide, 14 days for glutaraldehyde), 5 reprocessing cycles per day, 1-gallon basin for manual processing, and 4-gallon tank for automated processing.

+ = least expensive;

+++++ = most expensive
