Level of Disinfectant Activity. CIDEX OPA Solution is a high level disinfectant of semicritical devices above its Minimum Effective Concentration (MEC) of 0.3% as determined by the CIDEX OPA Solution Test Strip, when used or reused according to the Directions for Use, at 20oC for an immersion time of at least 10 minutes and a reuse period up to a maximum of 14 days. Reuse Period for Disinfection. CIDEX OPA Solution has demonstrated disinfection efficacy in the presence of 5% organic soil contamination and microbiological burden during reuse. CIDEX OPA Solution may be reused for a period up to a maximum of 14 days provided the required conditions of ortho-phthalaldehyde concentration and temperature exist based upon monitoring described in the Directions for Use. DO NOT rely solely on days in use. Individual hospital results on reuse will vary. Reuse of CIDEX OPA Solution for up to 14 days was determined was determined using the US EPA Reuse Protocol and an analytical test procedure. Concentration of this product during its reuse life, must be verified by the CIDEX OPA Solution Test Strip to determine that the concentration of orthophthalaldehyde is above the MEC of 0.3%. The product must be discarded after 14 days, even if the CIDEX OPA Solution Test Strip indicates a concentration at or above the MEC.
