Here's an analysis of the acceptance criteria and study detailed in the provided 510(k) summary for the EasyPlus Self Monitoring Glucose Test System:
Acceptance Criteria and Device Performance
The provided document does not explicitly state formal "acceptance criteria" with predefined thresholds that the device had to meet. Instead, it presents performance characteristics (precision, linearity, method comparison) and implies that these characteristics are acceptable because they are comparable to a predicate device and align with general guidelines (e.g., ISO 15197:2003, though the specific clauses for acceptance aren't detailed).
However, based on the performance data presented, here's a table summarizing the reported device performance, with an interpretation of what would generally be considered acceptable for a blood glucose monitor. Please note that the "Acceptance Criteria" column is a general interpretation based on industry standards for glucose meters, as the document itself does not explicitly list these as formal acceptance criteria.

Study Information
-
Sample size used for the test set and the data provenance:
- Precision (Within-run): Total 1200 tests (6 glucose levels x 200 tests each for N). Data provenance is not specified, but the study was conducted internally by EPS Bio Technology Corp. (Taiwan, R.O.C.). It's a prospective internal lab study.
- Precision (Day-to-day): Total 1200 measurements (3 control solutions x 400 measurements each for n). Data provenance not specified; prospective internal lab study.
- Linearity: 630 tests (7 glucose ranges x 10 meters x 3 strip lots assumed, based on the text "among the seven glucose ranges per each strip lot."). This is an internal lab study.
- Method Comparison: 205 people with diabetes. Data provenance not specified, but given the company location, likely Taiwan, R.O.C. This is a prospective clinical study involving actual patient samples.
- Interference Testing: Not explicitly stated how many samples per interferent, but conducted internally.
-
Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- Precision and Linearity: The ground truth or reference method was the preparation of specific glucose concentrations in blood samples. This does not involve human experts establishing ground truth in the traditional sense, but rather laboratory techniques with reference standards (NIST Traceability mentioned).
- Method Comparison: The YSI Glucose Analyzer was used as the reference method (ground truth) for blood glucose measurements. The YSI is a laboratory reference instrument, not a human expert.
-
Adjudication method (e.g. 2+1, 3+1, none) for the test set:
- No human adjudication method was used for establishing ground truth in these analytical performance studies. The ground truth was established by laboratory reference methods (YSI glucose analyzer, NIST traceable standards).
-
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 MRMC comparative effectiveness study was done. This device is a self-monitoring blood glucose system, which measures glucose levels directly, rather than relying on human interpretation of images or other subjective data that would necessitate an MRMC study.
-
If a standalone (i.e. algorithm only without human-in-the loop performance) was done:
- Yes, the performance studies presented (precision, linearity, detection limit, analytical specificity) are all standalone performance evaluations of the device's accuracy and reliability in measuring glucose. The method comparison also evaluates the device's standalone performance against a gold standard (YSI). While a healthcare professional also used the device, this was to compare their use to the YSI, and the patient use was also standalone. The device is designed for independent use.
-
The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- For precision, linearity, and analytical specificity, the ground truth was established using known concentrations of glucose (often prepared using NIST traceable standards) in blood or control solutions.
- For method comparison, the ground truth was established using a laboratory reference method, specifically the YSI Glucose Analyzer. The YSI is a highly accurate and widely accepted laboratory instrument for measuring blood glucose, often considered a "gold standard" for such comparisons.
-
The sample size for the training set:
- The document does not explicitly mention a "training set" in the context of machine learning or AI models. This device is an electrochemical biosensor. Its "training" is inherent in its design and calibration, not in a separate software training phase with a distinct dataset. The performance characteristics studies are for validation of the device, not for training.
-
How the ground truth for the training set was established:
- As there's no mention of a traditional "training set" for an AI/ML algorithm, this question isn't directly applicable. The device's calibration would be based on known glucose concentrations using highly accurate reference methods, presumably traceable to international standards (NIST traceability is mentioned for the device itself).

L. Test Principle:
The EasyPlus Self Monitoring Blood Glucose System employs a disposable dry reagent strip technology, based on the glucose oxidase method for glucose determination. Each test strip features an electrode containing the enzyme glucose oxidase (Aspergillus niger). A blood sample is applied to the blood collection area at the tip of the strip and is automatically drawn into the reaction zone, where the glucose oxidase catalyzes the oxidation of glucose to produce qluconic acid. During the reaction, a mediator transfers electrons to the electrode surface and generates a current. The amount of the current is proportional to the amount of glucose present in the blood sample. The glucose concentration is displayed on the meter screen after 5 seconds.
M. Performance Characteristics (if/when applicable):
-
- Analytical performance:
- a. Precision/Reproducibility:
Within-run - Testing was conducted by taking 4 mL of blood that was treated with heparin through a vacuum tube. Glucose was added to the 4 mL of blood to generate 6 different levels of glucose concentration for the test. Each of the samples was measured 10 times. The glucose concentration ranges were: 30-50 mg/dL, 51-110 mg/dL, 111-150 mg/dL, 151-250 mg/dL, 251-400 mg/dL, and 401~550 mg/dL.
| Range(mg/dL) | N | EasyPlus | ||
|---|---|---|---|---|
| mean(mg/dL) SD(mg/dL) | CV(%) | |||
| 30~50 mg/dL | 200 | 56.3 | 3.5 | 6.2 |
| 51~110 mg/dL | 200 | 100.0 | 4.5 | 4.5 |
| 111~150 mg/dL | 200 | 134.0 | 5.6 | 4.2 |
| 151~250 mg/dL | 200 | 189.6 | 5.2 | 2.7 |
| 251~400 mg/dL | 200 | 313.5 | 8.9 | 2.8 |
| 401~550 mg/dL | 200 | 479.7 | 10.4 | 2.2 |
'Day to day - Three control solutions of Low, Normal and High were prepared. Each of the controls was measured twice a day, once in the morning and once in the afternoon for a month.
| Control | n | mean (mg/dL) | SD (mg/dL) | CV (%) |
|---|---|---|---|---|
| Low | 400 | 59.3 | 3.0 | 5.1 |
| Normal | 400 | 131.6 | 3.5 | 2.7 |
| High | 400 | 389.3 | 12.4 | 3.2 |
b. Linearity/assay reportable range:
A blood sample of 25 mL was taken, treated with heparin vacuum tube, to be set
{4}------------------------------------------------
for a day. Testing was performed using whole blood supplemented with B-Dglucose to provide samples at seven different blood glucose levels (30-50 mg/dL, 51-80 mg/dL, 81-120 mg/dL, 121-200 mg/dL, 201-300 mg/dL, 301-400 mg/dL, and 400-550 mg/dL). A total of 210 tests were performed using 10 meters among the seven glucose ranges per each strip lot.
The linear regression was as follows: v = 0.9722x -0.1682, 2 = 0.9956, Svx = 9.38, N = 630
- Traceability, Stability, Expected values (controls, calibrators, or methods): C. Traceability referenced to NIST Standards, and it cleared with predicate device.
- d. Detection limit:
Data was provided to support a reportable range of 30-550 mg/dL.
- e. Analytical specificity:
Interference testing was conducted to determine the effect of select endogenous and exogenous substances. A series of test samples, systematically varying in the concentration of the interferents, was prepared by making quantitative, volumetric mixtures of two pools: one at the highest concentration to be tested and the other at the lowest. The substances and concentrations of the interferents are recommended in CLSI EP7-P.
Interference from dopamine and L-dopa was observed when the recommended concentration of these drugs was reached in the blood. Interference was also observed in higher than therapeutic dosages of acetaminophen, gentisic acid, and methvidopa.
