Intended Use

The Healgen Series Urine Reagent Strips and Urine Analyzers are in-vitro test systems intended for qualitative and semi-quantitative analysis of Urobilinogen, Bilirubin, Ketone, Blood, Protein, Nitrite, Leucocytes, Glucose, Specific gravity, pH and Ascorbic Acid in urine. The test systems consist of the Healgen Series Reagent Strips (Healgen 10 and Healgen 11) and the Healgen 500 or Healgen 800 Urine Analyzers. The Healgen 10 and 11 strips can be read visually and instrumentally with the Healgen 500 and 800 Analyzers. The Healgen 4 reagent strip can be read visually only. The Healgen Series Urine Reagent Strips and Urine Analyzers are intended for use to detect conditions indicating possible diabetes, metabolic abnormalities, liver diseases, kidney function, and urinary tract infections. Test results can be used along with other diagnostic information to rule out certain disease states and to determine if microscopic analysis is needed.

Device Description

Healgen Series Reagent strips for Urinalysis and urine analyzers are in vitro diagnostic test devices that use reagents for qualitative and semiquantitative urinalysis.

The device is composed of several color pads aligned on a strip. Each pad is employed for testing one assay item by visually or instrumentally reading the color change of the pad and comparing with the corresponding blocks on a color chart.

Healgen Series Reagent Strip provides tests for Glucose, Bilirubin, Ketone, Specific Gravity, Blood, pH, Protein, Urobilinogen, Nitrite, Ascorbic Acid and Leukocytes in Urine.

AI/ML Overview

Here's an analysis of the provided text regarding the acceptance criteria and study data for the Healgen Series Reagent Strips and Analyzers for Urinalysis:

Overview:
The submission (K111999) describes the Healgen Series Reagent Strips and Analyzers, in-vitro diagnostic devices for qualitative and semi-quantitative urinalysis of various analytes. The primary goal of the submission appears to be demonstrating substantial equivalence to a predicate device (URISTK H Series Reagent Strips for Urinalysis and Dirui H-50, H-100, or H-500 Urine Analyzer). The information provided largely focuses on the analytical performance of the device rather than a clinical outcome study.


1. Table of Acceptance Criteria and Reported Device Performance

The provided document describes analytical performance characteristics but does not explicitly state acceptance criteria for a "device meets acceptance criteria" study in the typical sense of a clinical trial with predefined end-points for sensitivity/specificity. Instead, it demonstrates the analytical capabilities and equivalence to a predicate device.

The tables below summarize the reported analytical performance related to:

  • Analytical Limits (Cutoff): These are the thresholds at which a positive or negative result is typically determined.
  • Reportable Ranges: These define the concentration ranges within which the device can provide meaningful qualitative or semi-quantitative results.
  • Analytical Specificity (Interference Study): This identifies substances and their concentrations that do not affect the test results.

2. Sample Size Used for the Test Set and Data Provenance

  • Sample Size for Precision (repeatability/reproducibility):
    • Within-run: 20 replicates for each of 3 urine control levels, using strips from 3 lots.
    • Within-day: 3 urine control levels analyzed in duplicate, once a day, for 10 days, using strips from 3 lots.
    • Analytical Specificity: 5 test strips from each of 3 lots for each interference test.
  • Sample Size for Clinical Comparison Studies: Not explicitly stated with a specific number of clinical specimens. The text only mentions "clinical comparison studies were conducted in 3 sites using the Healgen 11 Reagent Strip for Urinalysis and the predicate devices."
  • Data Provenance: Not explicitly stated (e.g., country of origin). The document implies the studies were conducted to support a submission to the US FDA, but does not specify the geographic location of the clinical sites or specimen collection. The study appears to be prospective for the analytical performance evaluations (precision, specificity) as these were performed as part of the validation. The "clinical comparison studies" also imply prospective data collection for comparison purposes.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

  • Experts: The precision study involved "6 technicians" across 3 clinical sites. No specific qualifications (e.g., years of experience, specific certifications) are provided for these technicians, nor are they explicitly stated as "experts establishing ground truth."
  • Ground Truth Qualification: For the precision and analytical specificity studies, the ground truth was established by using urine controls (Bio-Rad Level 1 and Level 2) and a 3rd control with analyte concentrations around cutoff, which was created by pooling Bio-Rad controls and spiking with pure analytes. For the clinical comparison study, the "ground truth" was implicitly the result obtained by the predicate device, as the study aimed to show comparability. There is no mention of external expert consensus or a gold standard method separate from the predicate for establishing ground truth for the clinical specimens.

4. Adjudication Method for the Test Set

  • No explicit adjudication method (e.g., 2+1, 3+1) is mentioned. The analytical studies used technical replication (e.g., 20 replicates, duplicates over 10 days). For the clinical comparison, the comparison was made against the predicate device, suggesting the predicate's results served as the reference for comparability.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and Effect Size of Human Improvement

  • No, an MRMC comparative effectiveness study was not explicitly described in the provided text in the typical sense of measuring human reader improvement with AI assistance.
  • The document mentions "visual reading" alongside "instrumental reading" for the Healgen strips and states that "comparable testing data could be obtained by intended users when using the Healgen 11 Reagent Strip for Urinalysis and the legally marketed URISTK H Series Reagent Strips for Urinalysis from Dirui." This indicates a comparison between visual and instrumental readings, and between the new device and the predicate. However, it does not detail a study specifically designed to assess human reader improvement with AI (in this case, the analyzer acting as an 'AI' for reading strips) versus without it.
  • The effect size of how much human readers improve with AI vs without AI assistance is not provided or discussed. The focus is on the performance comparability of the device (both visual and instrumental readings) to a predicate device.

6. If a Standalone (Algorithm Only Without Human-in-the-Loop Performance) Was Done

  • Yes, a form of standalone performance was implicitly studied for the instrumental reading. The Healgen 500 and 800 Urine Analyzers use "reflectance photometry to quantitate analyte values" and provide "instrumental reading." Precision, analytical limits, and reportable ranges are characteristics of the instrument's performance (the "algorithm") when reading the strips. The "analytical specificity" study also evaluates the instrument's performance in the presence of interfering substances. While not strictly an "AI algorithm" in the modern interpretative sense, the analyzers are automated systems that perform the reading without human interpretation beyond initiating the test and reading the display.

7. The Type of Ground Truth Used

  • For analytical performance (precision, reportable ranges, analytical specificity): The ground truth was based on controlled lab-prepared samples using Bio-Rad urinalysis controls and custom-spiked controls with known analyte concentrations.
  • For clinical comparison studies: The ground truth was the results obtained from the predicate device (URISTK H Series Reagent Strips for Urinalysis and Dirui H-50, H-100, or H-500 Urine Analyzer).

8. The Sample Size for the Training Set

  • The document does not explicitly mention a separate "training set" for an AI or machine learning model. This is consistent with the nature of reflectance photometry-based devices, which typically rely on calibrated physics-based models rather than data-driven machine learning for their primary function of quantifying color changes. The development of the reagents and the instrumental reading parameters would be based on chemical principles and extensive analytical validation rather than a distinct machine learning training set.

9. How the Ground Truth for the Training Set Was Established

  • As a distinct "training set" for AI/ML is not described, the concept of establishing ground truth for it is not applicable in the context of this submission. The device's operational parameters and measurement accuracy are established through the analytical performance studies rather than a machine learning training process.

Predicate Device: URISTK H Series Reagent Strips for Urinalysis and Dirui H-50, H-100, or H-500 Urine Analyzer manufactured by Dirui Industrial Co. Ltd (K040703).

Device Description Healgen Series Reagent strips for Urinalysis and urine analyzers are in

vitro diagnostic test devices that use reagents for qualitative and semiquantitative urinalysis.

The device is composed of several color pads aligned on a strip. Each pad is

{1}------------------------------------------------

employed for testing one assay item by visually or instrumentally reading the color change of the pad and comparing with the corresponding blocks on a color chart.

Healgen Series Reagent Strip provides tests for Glucose, Bilirubin, Ketone, Specific Gravity, Blood, pH, Protein, Urobilinogen, Nitrite, Ascorbic Acid and Leukocytes in Urine.

Intended Use/Indications for Use

Healgen Series Reagent Strips for Urinalysis are in vitro diagnostic test devices that use reagents for qualitative and semi-quantitative urinalysis. The strips are for professional use only.

Healgen Series Reagent Strips for Urinalysis are intended for use to detect conditions indicating possible diabetes, metabolic abnormalities, liver diseases, kidney function, and urinary tract infections. Test results can be used along with other diagnostic information to rule out certain disease states and to determine if microscopic analysis is needed.

Test principles

Urobilinogen: this test is based on the Ehrlich reaction in which p-diethylamino benzaldehyde in conjunction with a color enhancer reacts with urobilinogen in a strongly acid medium to produce a pink-red color.

Bilirubin: The direct bilirubin and dichlorobenzene diazonium produce fuchsia azo dyes in a strongly acid medium.

Ketone: The acetoacetate and sodium nitroprusside cause a reaction in the alkaline medium, which produces a violet color.

Blood: Hemoglobin acts as a peroxidase. It can cause peroxidase to release neo-ecotypes oxide [O]. [0] oxidizes the indicator and causes the color change.

Protein: The test is based on the protein-error-of-indicators principle. An ion in the specific pH indicator attracted by cation on the protein molecule makes the indicator further ionized, which changes its color.

Nitrite: Nitrite in the urine and aromatic amino sulphanilamide are diazotized to form a diazonium compound. The diazonium compound reacting with tetrahydro benzo (h) quinolin 3-phenol causes the color change.

Leukocytes: Granulocyte leukocytes in urine contain esterase that catalyzes the hydrolysis of the pyrrole amino acid ester to liberate 3-hydroxy-5-pheny pyrrole reacting with diazonium forms a purple color.

Glucose: The glucose oxidized by glucose oxidase catalyzes the formation of glucuronic acid and peroxide hydrogen. Peroxide hydrogen releases neo-ecotypes oxide [0] under the function of peroxidase. [O] oxidizes iodide potassium, which causes the color change.

Specific Gravity: Electrolyte (M+X-) in the form of salt in urine reacts with poly methyl vinyl ether and maleic acid (-COOH), which is a weak acid ionic exchanger. The reaction produces hydrogenous ionogen, which reacts with a pH indicator that causes the color change.

pH: This test is based on a double indicator principle that gives a broad range of colors covering the

{2}------------------------------------------------

entire urinary pH range.

Ascorbic Acid: Ascorbic acid, with 1, 2-dihydroxy alkenes, under the alkaline condition, deoxidizes the blue 2, 6-dichloroindophenolate into colorless N- (p-phenol)-2, 6-dichloro-p-amine phenol.

Performance

The following are performance characteristics of the Healgen Series Reagent Strips for Urinalysis and Healgen Series Urine Analyzers.

a. Analytical limits (cutoff):

We demonstrated the analytical limits of each assay item as below:

AnalyteUnitCutoff
Urobilinogenmg/dl0.7
Bilirubinmg/dl0.7
Ketonemg/dl3.5
Bloodcells/µL6.5
Proteinmg/dl7.2
Nitriteµg/dL50
Leukocytescells /µL10
Glucosemg/dl65
Ascorbic Acidmg/dl6.5
pH5.6
Specific Gravity1.003.

b. Precision (repeatability/reproducibility):

Within-run and within-day precisions were determined at 3 clinical sites by 6 technicians.

In within-run precision testing, 20 replicates were run on each of the 3 levels of urine controls. Each of the 20 replicates was assayed consecutively, using strips obtained from each of 3 lots strips.

In within-day precision testing, the 3 levels were analyzed in duplicate, one a day, for 10 days using strips obtained from 3 lots of strips.

All the 3 formats (Healgen 11, 10 and 4) strips and both of the reading method were used to perform the abovementioned evaluation. For instrumental reading, both Healgen 800 were used.

Urinalysis control Level 1 and Level 2 of Bio-Rad and a 3rd control with analyte concentrations around cutoff were used as samples for lower and higher levels.

The 3rd control was obtained by pooling the Bio-Rad controls and spiking with certain kinds of pure analytes to make all the analyte concentrations near the cutoff values.

{4}------------------------------------------------

c. Reportable ranges:

Healgen Series Reagent Strips for Urinalysis are qualitative and semi-quantitative. The strips give results in a small range of concentration of each analyte. All the output values of Healgen Series Reagent Strips are within the laboratory assay ranges. The laboratory assay range and the reportable range of Healgen strips for each analyte are listed in the following table:
