Intended Use
The Minuteful - kidney test is an in-vitro diagnostic, home-use urine analysis test system for the semi-quantitative measurement of albumin and creatinine in urine, as well as the presentation of their ratio, the albumin-creatinine ratio (ACR). The system consists of a smartphone application, proprietary Color-Board and an ACR Reagent Strip. The system is available for prescription-use only and is intended for people at risk of kidney disease. Results are used in conjunction with clinical evaluation as an aid in the assessment of kidney health.
Device Description
The Minuteful - kidney test is comprised of a kit and a smartphone application. It is intended for the semi-quantitative measurement of albumin and creatinine in urine, as well as the presentation of their ratio, the albumin-creatinine ratio (ACR). The Minuteful - kidney test is intended for prescription-use only, as a home-use device to aid in the assessment of kidney health. The results can be used together with clinical evaluation to guide patient care. The device's kit includes a urine receptacle, an ACR Reagent Strip, an absorbing (i.e. "blotting") pad, a proprietary Color-Board and a user manual. The device also consists of an easy-to-use smartphone application, image recognition algorithms, and a physician compendium. The software component of the Minuteful - kidney test consists of both an application (app) and a backend server. Both components encompass different computer vision and machine learning algorithmic components, performing the image analysis activities. The app instructs the user how to accurately administer the test. The Image Validation Transfer System (IVTS) component of the Minuteful - kidney test enables its usage across a wide range of smartphone types and operating systems, essentially making the test platform agnostic.
More Information

Yes
The device description explicitly states that the software component encompasses "machine learning algorithmic components, performing the image analysis activities."

No.
The device is described as an in-vitro diagnostic test system for measuring albumin and creatinine, used as an aid in assessing kidney health, not for treating or preventing disease.

Yes

The "Intended Use / Indications for Use" section explicitly states that the device is "an in-vitro diagnostic, home-use urine analysis test system" and that "Results are used in conjunction with clinical evaluation as an aid in the assessment of kidney health," which unequivocally identifies it as a diagnostic device.

No

The device description explicitly states that the system consists of a smartphone application, proprietary Color-Board, and an ACR Reagent Strip, and the kit includes physical components like a urine receptacle, reagent strip, blotting pad, and Color-Board. This indicates it is a system with both hardware and software components, not software-only.

Yes, the device is an IVD (In Vitro Diagnostic).

The "Intended Use / Indications for Use" section explicitly states: "The Minuteful - kidney test is an in-vitro diagnostic, home-use urine analysis test system..."

This statement directly identifies the device as an in-vitro diagnostic.

No
The letter does not mention that the FDA has reviewed and approved or cleared a Predetermined Change Control Plan (PCCP) for this specific device.

Summary of Performance Data:

Healthy.io conducted multiple validation studies including the Limit of Detection and the set of IVTS studies to ensure the modified device is substantially equivalent to the predicate device (Minuteful - kidney test K210069). The rest of the analytical performance studies are still relevant for the modified version of the Minuteful - kidney test, and their summary is available in the predicate device documentation (K210069).

Performance Testing:

The performance characteristics of the Minuteful - kidney test were evaluated according to the following performance tests:

Limit of Detection (LoD):

Testing of the Minuteful - kidney test detection limits was designed and executed in accordance with guidance provided by the Clinical and Laboratory Standards Institute (CLSI) document EP17-A2 - Evaluation of Detection Capability for Clinical Laboratory Measurement Procedures; Approved Guidelines - Second Edition.

Illumination Conditions:

This study consisted of two separate studies; the Multiple Illuminations and Extreme Illuminations studies.

  • . Multiple Illuminations: Testing was conducted under different lighting conditions of different color temperatures and intensities from different light sources representative of those that may be used in the home setting. The results of the study support that the performance is not impacted by lighting conditions that are likely to be found in the home use environment.
  • Extreme Illuminations: Testing was conducted under different lighting conditions with . different saturation of the RGB spectrums as well as under different light intensities. Tested smartphones were evaluated at the edges of the device boundary conditions, under which the device allowed the smartphone to take an image of the urine test strip and Color-Board. The results of this testing support that the device performance is not impacted by different light color saturations.

Physical Conditions:

Testing was conducted under different distance conditions and different angle conditions. Tested smartphones were evaluated at the edges of the device boundary conditions, under which the device allowed the smartphone to take an image of the urine test strip and Color-Board. The performance of the device was not impacted within the supported conditions.

Multiple Shadow conditions:

Testing was conducted under different shadow configurations of different intensity and covering different portions of the Color-Board and urine test strip. Tested smartphones were evaluated at the edges of the device boundary conditions, under which the device allowed the smartphone to use the captured image of the urine test strip and Color-Board. The performance of the device was not impacted by the presence of shadows on the color-board and test strip within the supported conditions.

8

Blurriness:

Testing was conducted under different conditions of blurred images consisting of different levels of focus and motion blur. Tested smartphones were evaluated at the edges of the device boundary conditions, under which the device allowed the smartphone to take an image of the urine test strip and Color-Board. The performance of the device was not impacted by the image blur within the supported conditions.

Misplaced Urine Stick:

Testing was conducted under different urine test strip placements. Tested smartphones were evaluated at the edges of the device boundary conditions, under which the device allowed the smartphone to use the captured image of the urine test strip and Color-Board. The performance of the device was not impacted by the test strip placement within the supported conditions.

Dirty Color-Board:

Testing was conducted under different dirty substances covering different parts of the Color-Board. consisting of different levels of focus and motion blur. Tested smartphones were evaluated at the edges of the device boundary conditions, under which the device allowed the smartphone to use the captured image of the urine test strip and Color-Board. The performance of the device was not impacted by the dirty substances within the supported conditions.

Precision: See Minuteful - kidney test summary (K210069).

Interference: See Minuteful - kidney test summary (K210069).

Linearity: See Minuteful - kidney test summary (K210069).

Stability: See Minuteful - kidney test summary (K210069).

Clinical Performance Testing:

Method Comparison: See Minuteful - kidney test summary (K210069).

Conclusion:

The modified Minuteful - kidney test is substantially equivalent to the predicate device Minuteful kidney test cleared in K210069.
