Intended Use

The Serim® DISINTEK™ OPA Test Strip is a chemical indicator for use in determining whether the concentration of ortho-phthalaldehyde, the active ingredient in Metricide OPA Plus Solution, is above or below the minimum effective concentration (MEC) established for Metricide OPA Plus Solution.

Device Story

The Serim DISINTEK OPA Test Strip is a qualitative, single-use chemical indicator designed to verify the potency of Metricide OPA Plus Solution. The device consists of a 0.4-inch square reagent-treated test pad affixed to a polystyrene strip. Operation involves dipping the test pad into the OPA solution; a two-step chemical reaction occurs. First, OPA at concentrations up to 0.3% reacts to form a colorless product. Second, any OPA concentration exceeding the 0.3% MEC reacts with a second chemical to produce a green color. The user visually interprets the color change to determine if the solution is above or below the MEC. This provides healthcare providers with a rapid method to ensure the disinfectant solution remains effective for its intended use, thereby supporting proper high-level disinfection protocols and patient safety.

Clinical Evidence

No clinical data. Performance was established via bench testing using split-sample blind studies comparing the Serim DISINTEK OPA Test Strip to the predicate Metricide OPA Plus Solution Test Strip.

Technological Characteristics

Qualitative chemical indicator strip; 0.4" x 0.4" reagent-treated test pad on a 3.25" x 0.4" white opaque polystyrene strip. Sensing principle: two-step chemical reaction (colorless product at ≤0.3% OPA; green color at >0.3% OPA). Single-use.

Indications for Use

Indicated for use as a chemical indicator to determine if the concentration of ortho-phthalaldehyde (OPA) in Metricide OPA Plus Solution is above or below the minimum effective concentration (MEC) of 0.3%.

Regulatory Classification

Identification

Biological sterilization process indicator: A device intended for use by a health care provider to accompany products being sterilized through a sterilization procedure and to monitor adequacy of sterilization. The device consists of a known number of microorganisms, of known resistance to the mode of sterilization, in or on a carrier and enclosed in a protective package. Subsequent growth or failure of the microorganisms to grow under suitable conditions indicates the adequacy of sterilization. Physical/chemical sterilization process indicator: A device intended for use by a health care provider to accompany products being sterilized through a sterilization procedure and to monitor one or more parameters of the sterilization process. The adequacy of the sterilization conditions as measured by these parameters is indicated by a visible change in the device.

Technological Characteristics: The Serim DISINTEK OPA Test Strips contains two reacting chemicals, a stabilizer, and other non-reacting ingredients. The reaction process involved with the test strip is based on a two step reaction. The first step involves a reaction in which a chemical at a concentration equivalcnt to 0.3% OPA (MEC) reacts with the OPA to form a colorless product. A second reaction then occurs in which OPA at levels above 0.3% reacts with a second chemical to form a colored compound, resulting in green color. The test pad size of 0.4" x 0.4" allows for easy interpretation of the change in color. The device will reliably indicate if the OPA concentration is above or below the MEC level of 0.3% OPA.

- Performance: The performance of the Serim DISINTEK OPA Test Strips was evaluated in split samples blind studies and compared to test results obtained with Metricide OPA Plus Solution Test Strips. The performance of the Serim DISINTEK OPA Test Strips is substantially equivalent to the predicate device, Metricide OPA Plus Solution Test Strips.
- Conclusion: The Serim DISINTEK OPA Test Strips have the same intended use as the predicate device. Both test strips measure the potency of OPA in Metricide OPA Plus Solution, above or below the Minimum Effective Concentration of 0.3%. The Serim DISINTEK OPA Test Strips do not raise any new safety or effectiveness issues.
