No
The device is a visually read urine strip with a color chart for interpretation, and the summary explicitly states "Laboratory instrumentation is not required" and "Mentions AI, DNN, or ML: Not Found".
No
The device is a diagnostic tool used to detect glucose and protein in urine, providing information about health status, rather than directly treating or preventing disease.
Yes
The device detects specific markers (glucose and protein) in urine, and the results provide information about a person's metabolic and kidney function, which is a characteristic of a diagnostic device.
No
The device description explicitly states it consists of "glucose and protein reagent pads that are affixed onto firm plastic strips" and is a "disposable" physical product. It does not mention any software component.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The description explicitly states the device is for "detection of glucose and protein in urine" and that "Test results may provide information regarding the status of carbohydrate metabolism and kidney function." This clearly indicates the device is used to examine specimens derived from the human body (urine) to provide information for diagnostic purposes.
- Device Description: The device works by reacting with a urine sample and producing a color change based on the presence and concentration of glucose and protein. This is a typical mechanism for in vitro diagnostic tests.
- Performance Studies: The document describes clinical and laboratory studies conducted to evaluate the performance of the device using urine samples. This is a requirement for demonstrating the safety and effectiveness of an IVD.
- Predicate Device: The mention of a predicate device (K940469; Urine Reagent Strip-3 Parameter) which is also an IVD further supports that this device falls under the same category.
The fact that it is intended for "prescription home use" and "visually read" does not change its classification as an IVD. It is still performing a diagnostic test on a biological sample outside of the body.

Device Description
This device consists of glucose and protein reagent pads that are affixed onto firm plastic strips. The reagent pad areas are made of absorbent material saturated with chemically active substance, then dried and affixed to the plastic strip with double-sided adhesive. Each strip is carefully packaged individually along with a desiccant in a sealed, foiled pouch. A packaged along with the foil pouches into a box. The package insert contains all the necessary product information.
Results of each test is based on the color produced from the reaction of each reagent pad area once the reagent strip comes into contact with a urine sample. Each parameter is color coded accordingly as described in the color chart. Results can be obtained in clinically meaningful units directly, by comparison with the color chart on the foil pouch. The color blocks represent different concentrations of urine glucose and urine protein. The entire reagent strip is disposable following federal and local regulations. Laboratory instrumentation is not required.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
A comparison study was performed at three clinical sites by having lay users (n= 162) testing the URS-2GP using mid-stream urine samples, and healthcare professionals testing the sample using a comparator device (URS-3, Teco Diagnostics). The participants were asked to match the test colors with specific color blocks on the color chart and record the glucose and protein values. The data presented here showed that the tests performed by lay users had 92% agreement based on exact match and 100% agreement within one color block.
The laboratory studies were conducted in house and included sensitivity, precision, interference, stress and stability studies. The obtained laboratory data indicated that the new device had the similar performance characteristics as the predicate device.
Key Metrics (Sensitivity, Specificity, PPV, NPV, etc.)
Precision: Multiple tests were performed under variable conditions using multiple users, sites and lots of urine controls. The tests were performed using Within Run method (multiple runs within a day) and Run-to-Run method (multiple runs on multiple days). The results showed that the device has 96% agreement based on exact match and 100% agreement within one color block).
Sensitivity: The sensitivity range for each color block was determined by performing multiple tests at various concentrations of analyte near each color block. Sensitivity range of a color block is determined by the concentrations where 95% of the test results vielded correct results.
Specificity: The device was tested with compounds similar to glucose and protein to determine if it has crossreactivity. The glucose analogues tested included galactose, fructose, and sucrose, while the protein analogues tested included globulin, hemoglobin, Bence Jones, and mucoprotein. The glucose test did not react with any of the glucose analogues at concentrations up to 500 mg/dL. The protein test was specific for albumin, but also had some reactivity to globulin and Bence-Jones protein at concentrations higher than 100 mg/dL.
Interference: The device was tested in the presence of potential interfering compounds which may affect the urine glucose and urine protein tests. A substance is considered to cause interference if the addition of the substance causes the test reading to be off by at least one color block. The results showed that ascorbic acid (50 mg/dL) and MESNA (25 mg/dL) had intefference effect on the urine glucose test. MESNA (25 mg/dL) also had interference effect on the urine protein test, while ascorbic acid up to 500 mg/dL had no effect on the urine protein test. Hemoglobin concentration of 100 mg/dL or above causes atypical color of urine which renders the urine glucose and urine protein tests invalid.

Test Principles:
Glucose: This test is based on a double sequential enzyme reaction. One enzyme, glucose oxidase, catalyzes the formation of gluconic acid and hydrogen peroxide from the oxidation of glucose. A second enzyme, peroxidase, catalyzes the reaction of hydrogen peroxide with potassium iodide chromogen causing the color to change from blue-green for a "negative" reaction to greenish-brown through brown for a "positive" reaction.
Protein: This test is based on the protein error-of-indicator principle. At a constant pH, the development of any green color is due to the presence of protein. Colors range from yellow for a "negative" reaction to yellow-green and green to blue-green for a "positive" reaction.
Expected Results:
Glucose: Small amounts of glucose are normally excreted by the kidney. Glucose concentrations up to 100 mg/dL are considered normal, but may be abnormal if found consistently.
Protein: Small amounts of protein may be excreted by the normal kidney. Protein concentrations up to 15 mg/dL are considered normal, but may be abnormal if found consistently.

Based on a comparison of the device features, materials and intended use, this device is substantially equivalent to the following predicate device:
