One Step FSH Menopausal Test is a rapid chromatographic immunoassay for the qualitative detection of follicle stimulating hormone (FSH) in urine. The test utilizes a combination of antibodies including mouse monoclonal anti-FSH antibodies and goat polyclonal anti-mouse antibodies to selectively detect elevated levels of FSH.
Here's a breakdown of the acceptance criteria and study information based on the provided FDA 510(k) summary for the "One Step FSH Menopausal Test":
A. Acceptance Criteria and Reported Device Performance
The acceptance criteria for diagnostic tests often involve measures like sensitivity, specificity, and accuracy, especially when comparing to a reference method or clinical endpoint. While the specific numerical acceptance criteria established by the manufacturer are not explicitly detailed in this FDA letter (which typically focuses on substantial equivalence), the provided data implies a performance standard for "positive agreement" and "negative agreement" in comparison to a predicate device or clinical reference.
| Acceptance Criteria (Implied) | Reported Device Performance |
|---|---|
| Professional Use | |
| Positive Agreement | 90.3% |
| Negative Agreement | 92.2% |
| Overall Agreement | 91.5% |
| Lay Use | |
| Positive Agreement | 90.3% |
| Negative Agreement | 92.2% |
| Overall Agreement | 91.5% |
| Accuracy (Against Clinical Reference) | |
| Negative Reference | 92.2% |
| Positive Reference | 90.3% |
Note: The FDA 510(k) summary usually provides the specific acceptance criteria. This document indicates the device is "substantially equivalent," meaning its performance is comparable to a legally marketed predicate device, implicitly meeting accepted performance standards for its intended use.
B. Sample Size Used for the Test Set and Data Provenance
The provided document does not explicitly state the specific sample size used for the test set in a clinical study to validate these performance metrics. The agreement percentages (Positive Agreement, Negative Agreement, Overall Agreement) are listed, but the accompanying sample sizes for "Professional Use" and "Lay Use" are not present in this excerpt.
- Data Provenance: Not specified in this document. It does not mention the country of origin of the data or whether the study was retrospective or prospective.
C. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications
This information is not available in the provided document. For an FSH Menopausal Test, the "ground truth" for elevated FSH levels would likely be established by a laboratory assay (e.g., ELISA) for quantitative FSH levels, interpreted by a qualified medical professional (e.g., endocrinologist, gynecologist). The document doesn't detail the involvement of experts in establishing the ground truth or their qualifications.
D. Adjudication Method for the Test Set
This information is not available in the provided document. Adjudication methods (e.g., 2+1, 3+1) are typically used in imaging or subjective interpretation studies. For a diagnostic test like this, the ground truth is usually established by a reference method (e.g., quantitative laboratory FSH measurement), making multi-reader adjudication less relevant in the same way.
E. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was Done
No. A Multi-Reader Multi-Case (MRMC) comparative effectiveness study, which typically evaluates how AI assistance impacts human reader performance, is not applicable to a single-use, qualitative in-vitro diagnostic test like the One Step FSH Menopausal Test. This device is not an AI-assisted interpretation tool.
F. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was Done
Yes, in essence. This device inherently operates as a "standalone" test. The "performance" figures provided (Positive Agreement, Negative Agreement, Overall Agreement) reflect the device's ability to accurately detect FSH in urine samples, without human intervention in the detection process itself. The "Lay Use" section specifically evaluates its performance when interpreted by non-professionals, which is a key aspect of its standalone functionality for over-the-counter use.
G. The Type of Ground Truth Used
The ground truth used for performance evaluation is indicated by "Clinical Reference" and "Negative Reference" / "Positive Reference." This strongly suggests that the device's results were compared against an established clinical reference method for FSH levels (likely a quantitative laboratory assay) to determine true positive and true negative cases.
H. The Sample Size for the Training Set
This information is not available in the provided document. For a traditional in-vitro diagnostic test, there isn't a "training set" in the machine learning sense. The device's components (antibodies, reagents) are developed and optimized through research and development, but the sample sizes involved in that development process are distinct from the clinical validation (test set) discussed above.
I. How the Ground Truth for the Training Set Was Established
Not applicable in the machine learning sense. The "ground truth" for the development of such a test would involve confirming the specificity and sensitivity of the antibodies and reagents against known concentrations of FSH, using established laboratory standards and methods. This is part of the product development and quality control process, rather than a "training set" in AI/ML terminology.

One Step urine hCG (cassette format) Pregnancy Test is for the in vitro diagnostic use --- for the detection of hCG (human Chorionic Gonadotropin) presence in female urine specimens and in turn for the early detection of pregnancy. This test kit is used (only once) to obtain a visual and qualitative results for the Over-the-Counter Use.
Urine RCG (Cassette Format) One Step Test Kit
While the provided documents confirm FDA clearance for the Urine HCG (Cassette Format) One Step Test Kit and describe its intended use, they do not contain the detailed information required to describe the acceptance criteria and the study that proves the device meets those criteria in the format requested.
Specifically, the documents are a 510(k) clearance letter and an Indications for Use statement. These documents confirm substantial equivalence to a predicate device and outline the intended use, but they do not present the technical performance data, study design, or specific acceptance criteria in the way a scientific study report would.
Therefore, I cannot fulfill the request for information on acceptance criteria and study details based solely on the provided text.
However, based on what is typically expected for an in vitro diagnostic device like a pregnancy test and what might be inferred from such a regulatory submission, here's a general idea of what that information would look like if it were present:
Hypothetical Acceptance Criteria and Study Information (Based on typical IVDD requirements, NOT the provided document)
Since the provided document is an FDA clearance letter and an "Indications For Use" statement, it does not contain the detailed technical performance study information you are asking for. However, for a device like a pregnancy test, the following information would typically be part of the submission that led to this clearance:
1. Table of Acceptance Criteria and Reported Device Performance
| Performance Metric | Acceptance Criteria (Hypothetical) | Reported Device Performance (Hypothetical) |
|---|---|---|
| Sensitivity (Detection of hCG at 25 mIU/mL) | ≥ 99% | 99.5% |
| Specificity (Absence of hCG in negative samples) | ≥ 99% | 100% |
| Accuracy (Overall agreement with reference method) | ≥ 99% | 99.8% |
| Cross-Reactivity (Interference from related hormones) | ≤ 1% positive bias (LH, FSH, TSH) | No significant cross-reactivity observed |
| Hook Effect (High-dose insensitivity) | No hook effect up to 500,000 mIU/mL hCG | No hook effect up to 500,000 mIU/mL hCG |
| Expected Values (Correct identification of pregnant/non-pregnant samples) | Clinically acceptable range | Consistent with expected clinical outcomes |
| Precision (Reproducibility between runs/lots) | CV ≤ 10% | CV < 5% |
2. Sample Size Used for the Test Set and Data Provenance
- Sample Size: Typically, hundreds to thousands of urine samples would be used for a comprehensive clinical study. For a general pregnancy test, this might involve:
- Positive samples: 100-200 confirmed pregnant urine samples (various stages of pregnancy).
- Negative samples: 200-500 confirmed non-pregnant urine samples.
- Spiked samples: A range of hCG concentrations (e.g., 0, 10, 25, 50, 100, 500,000 mIU/mL) to assess sensitivity, linearity, and hook effect.
- Data Provenance: Likely a combination of:
- Prospective collection: From clinical sites within Canada (where the manufacturer is located) and potentially the US.
- Retrospective collection: Archived samples with known hCG status, potentially from various countries if adequately characterized.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
- Ground Truth Determination: For clinical samples, the ground truth for hCG status is typically established by:
- Confirmation with a highly sensitive and quantitative reference laboratory method: Such as a validated immunoassay (e.g., chemiluminescent immunoassay) performed at a College of American Pathologists (CAP) accredited laboratory.
- Clinical confirmation: Including follow-up with patient medical records for pregnancy confirmation (e.g., ultrasound, continued elevated hCG levels over time).
- "Experts": While individual "experts" don't typically "read" the ground truth for every sample, the ground truth is overseen by:
- Board-certified Clinical Pathologists or Clinical Biochemists: Supervising the reference laboratory testing. (e.g., Clinical Biochemist with 10+ years of experience, similar to Dr. David Lee's qualifications).
- Clinical Obstetricians/Gynecologists: Providing clinical correlation for patient outcomes.
4. Adjudication Method for the Test Set
- Not applicable in the typical sense for a quantitative ground truth. Adjudication (e.g., 2+1) is more common when human readers are involved in interpreting images or subjective results.
- For a quantitative ground truth (like a reference immunoassay), the result itself is the "adjudicated" truth, usually with established cut-off values. Discrepancies between the investigational device and the reference method would be resolved by re-testing (e.g., re-running both tests on an aliquot, using a third confirmatory method).
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
- Highly Unlikely for this device. This is a standalone diagnostic kit with a visual, qualitative result (a line appearing or not appearing). There are no "human readers" interpreting complex images or data that AI would assist with in this context. MRMC studies are typical for imaging AI, not for a simple in vitro diagnostic test like a pregnancy strip.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
- Yes, this is a standalone device. The performance claimed (sensitivity, specificity, accuracy) is inherently the "standalone" performance of the test kit itself, without a human interpretation component that could be "assisted" or compared to. The user simply observes the line/no line.
7. The Type of Ground Truth Used
- Reference Laboratory Assay + Clinical Outcomes: The primary ground truth would be established by a highly sensitive and quantitative laboratory hCG assay, combined with clinical correlation like ultrasound confirmation or longitudinal hCG observation to confirm pregnancy status.
8. The Sample Size for the Training Set
- Not applicable in the traditional "AI training set" sense. This device is a biochemical assay (lateral flow immunoassay), not an AI algorithm that undergoes machine learning training. The "training" for such a device involves iterative development and optimization of the reagents and strip components. The "test set" described above serves as the validation for the final product.
9. How the Ground Truth for the Training Set Was Established
- Not applicable. See point 8. The "ground truth" during development involves ensuring the assay correctly detects hCG at specific concentrations and does not cross-react with other substances, which is done through laboratory experiments using purified hCG and known interferents, not through a "training set" of patient data in the AI sense.
