High Range Peroxide™ Test Strip is intended for use as an efficacy test strip for measuring effective levels of peroxide in Renalin® disinfectant solution. Each time when the kidney unit is reprocessed with peroxide disinfectant solution such as Renalin® , the reprocessing solution should be monitored with the High Range Peroxide™ Test Strip to assure that Renaline concentration is 3% as it is intended to be. After the kidney is placed under storage until next use, the Renaling concentration in the disinfectant solution should be checked again before rinsing with the strip to assure that Renalins concentration has been maintained at 1% or higher. If the Renaling concentration drops below 1%, the kidney unit has to be either reprocessed or discarded.
High Range Peroxide™ Strip is a paper based dry chemistry reagent strip. It consists of a single reagent pad, 0.2x0.2 inch square, adhered to one end of a 0.2x2.5 inch plastic handle with a double sided adhesive. It is a self-contained, ready to use dip-andread reagent strip without additional reagent. The strip is packaged in 50 or 100's in bottles. Color blocks corresponding to Renalin8 concentrations of 0.2, 0.5, 1.0, 2.0 and 3.0 % are printed on the bottle label. Quantitative estimation of Renalink concentration can be made by comparing the strip color to the color blocks.
Here's a breakdown of the acceptance criteria and study information based on the provided text:
1. Table of Acceptance Criteria and Reported Device Performance
Acceptance Criteria (Stated or Implied) | Reported Device Performance |
---|---|
Qualitative detection of ≥1% Renalin concentration (equivalent to predicate device). | "[The IBT High Range Peroxide™ Test and Renalin Perassay™ 500 Test are] equally effective in detecting Positive, i.e., 1 % or higher, of Renalin® concentration in the kidney reprocessing solution." |
Quantitative measurement of Renalin concentration from 0.2% to 3.0%. | "The strip reactivity is modulated to provide a continuous reaction range with Renalin from 0.2 to 3.0 % or equivalent peroxide levels from 100 to 1,500 ppm. It can be used as a quantitative test for Renalink or other peroxide disinfectants." "Color blocks corresponding to Renalin® concentrations of 0.2, 0.5, 1.0, 2.0 and 3.0 % are printed on the bottle label. Quantitative estimation of Renalin® concentration can be made by comparing the strip color to the color blocks." |
Indication of effective Renalin concentration for kidney reprocessing (initially 3%, maintained at ≥1%). | Implied by intended use: The device is used "to assure that Renalin® concentration is 3% as it is intended to be" initially, and then "to assure that Renalin® concentration has been maintained at 1% or higher" during storage. The successful granting of 510(k) suggests the device meets this intended use. |
Note: The provided document is a 510(k) summary for a reagent strip, not a detailed clinical study report. Therefore, the "reported device performance" is described qualitatively as part of a substantial equivalency argument rather than with specific statistical metrics (e.g., sensitivity, specificity, accuracy percentages) which would be typical for more complex devices or software.
2. Sample Size Used for the Test Set and the Data Provenance
The document does not explicitly state a quantitative sample size for a "test set" in the context of a formal study with statistical reporting. The evaluation appears to be based on the chemical principle and a comparison to a predicate device.
- Data Provenance: Not explicitly stated as "country of origin" or "retrospective/prospective." The comparison is a direct technological comparison and statement of equivalence rather than a field test with patient data.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and the Qualifications of Those Experts
This information is not provided. Given the nature of a chemical reagent strip, "ground truth" would likely refer to known, prepared concentrations of Renalin® solution, verified by analytical chemistry methods, rather than expert interpretation of clinical data.
4. Adjudication Method for the Test Set
This information is not provided. Adjudication methods like 2+1 or 3+1 typically apply to studies where human interpretation of medical images or other complex data is involved. For a dip-and-read chemical strip, the "reading" is a visual comparison to color blocks.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
- No, an MRMC study was not conducted. This type of study is relevant to imaging devices or software where human readers interpret results, often with and without AI assistance. This device is a simple chemical reagent strip.
6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) was done
- This question is not applicable in the usual sense. The device is a "dip-and-read" reagent strip, meaning there is an inherent human "in-the-loop" visual comparison to color blocks. There is no automated algorithm that performs a standalone reading. The performance is the "human-in-the-loop" performance based on visual comparison.
7. The Type of Ground Truth Used
- The ground truth would be based on known, prepared concentrations of Renalin® solution (or equivalent peroxide levels). These concentrations would be analytically verified to ensure accuracy. The document refers to "Renalin® concentrations of 0.2, 0.5, 1.0, 2.0 and 3.0 %" as the basis for the color blocks, implying these are the known target values for the comparison.
8. The Sample Size for the Training Set
- This information is not provided and is generally not applicable for a simple chemical reagent strip of this nature. "Training set" typically refers to data used to train machine learning algorithms.
9. How the Ground Truth for the Training Set Was Established
- This information is not applicable as there is no "training set" in the context of machine learning. The "ground truth" for the development of the device (i.e., establishing the color scale for different concentrations) would have involved preparing solutions of known Renalin® concentrations and observing the color development on the strip.

WaterCleck™ CP Reagent Strip is intended to be used in detecting residual chlorine or peroxide in dialysis water. It also is used for detection of effective high level of chlorine in the disinfecting solution.
WaterCleck™ CP Reagent Strip is a paper based dry chemistry reagent strip. It consists of a single reagent pad, 0.2x0.2 inch square, adhered to one end of a 0.2x2.5 inch plastic handle with a double sided adhesive. The chemistry of the regent strip allows the same single reagent pad to react with either chlorine or peroxide. It is self-contained and is ready to use as a dip-and-read reagent strip without other additional reagent.
The provided text describes a medical device called "WaterCheck™ CP Reagent Strip for Chlorine and Peroxide." It focuses on its intended use, technological comparison to existing products, and a statement of substantial equivalence. However, the document does not contain the detailed acceptance criteria and study information typically found in a comprehensive medical device submission that would allow for a complete answer to your request.
Specifically, the document lacks:
- A table of acceptance criteria with reported device performance values.
- Details on sample sizes for test sets, data provenance, or information about training sets.
- Information on experts used to establish ground truth, adjudication methods, or MRMC studies.
- Data regarding standalone algorithm performance or the type of ground truth used in a formal study.
Therefore, I cannot fully answer your request with the provided information.
However, based on the limited information about performance claims, I can infer what might be considered acceptance criteria based on its comparison to predicate devices, but this is a reconstruction and not explicitly stated in the document.
Inferred Potential Acceptance Criteria and Reported Device Performance (Based on Substantial Equivalence Claims):
Parameter | Acceptance Criteria (Inferred from Predicate Equivalence) | Reported Device Performance (from text) |
---|---|---|
Residual Chlorine Detection | Detect 0.5 ppm or less of chlorine | Detect 0.5 ppm or less of chlorine. Can extend detection range to 1000 ppm or more (for high-level disinfection monitoring). |
Hydrogen Peroxide Detection | Detect 1.0 ppm of hydrogen peroxide | Detect 1.0 ppm of hydrogen peroxide. More sensitive to 0.5 ppm or less of hydrogen peroxide (compared to Renalin Strip). |
Hydrogen Peroxide Stability | Stable at room temperature (compared to predicate) | Stable at room temperature. |
