SpermCheck® Vasectomy is a rapid qualitative test that detects low concentrations of sperm at or above 250,000 sperm/mL in human semen as an aid for vasectomized men. For in vitro OTC home use.

SpermCheck® Vasectomy is an immunochromatographic test for the rapid, qualitative detection of sperm concentration.

The provided text describes the 510(k) summary for the SpermCheck® Vasectomy device. However, it does not include detailed information regarding acceptance criteria, specific study designs, sample sizes for test sets, ground truth establishment, or multi-reader multi-case studies. The document primarily focuses on establishing substantial equivalence to predicate devices and defining the intended use.

Therefore, many of the requested details cannot be extracted directly from the provided text. I will provide the information that is available and highlight what is missing.

Here's an analysis based on the provided text:

1. Table of Acceptance Criteria and Reported Device Performance

The document defines the device's capability but does not explicitly state acceptance criteria in terms of sensitivity, specificity, accuracy, or agreement percentages against a gold standard. It states the device "detects low concentrations of sperm at or above 250,000 sperm/mL".

The document mentions "SpermCheck® Vasectomy is substantially equivalent to standard microscopic analysis (counting by Hemacytometer) based on WHO guidelines in its performance". This implies that its performance is comparable to the hemacytometer, but specific metrics of this comparison are not provided.

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

This information is not provided in the given 510(k) summary. The document does not detail any specific clinical study data, sample size, or the origin (country, retrospective/prospective) of the data used for performance claims.

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

This information is not provided in the given 510(k) summary. Given the nature of the device (sperm concentration), the "ground truth" would typically involve laboratory analysis by trained personnel, but details are not included.

4. Adjudication Method for the Test Set

This information is not provided in the given 510(k) summary.

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

This information is not provided in the given 510(k) summary. The device is described as an "in vitro OTC home use" test, which suggests it is designed for direct user interpretation rather than being integrated into a workflow involving expert readers.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

Yes, the device is inherently a standalone test. It is a "rapid qualitative test" intended for "in vitro OTC home use." It operates as an immunochromatographic test, meaning the result is directly interpreted from the test strip by the user, without an algorithm or human-in-the-loop requiring additional interpretation beyond reading the visual result.

7. The Type of Ground Truth Used

The primary ground truth referenced for substantial equivalence is "standard microscopic analysis (counting by Hemacytometer) based on WHO guidelines." This implies a laboratory-based, expert-performed quantitative measurement that serves as the gold standard for sperm concentration.

8. The Sample Size for the Training Set

This information is not provided in the given 510(k) summary. As an immunochromatographic test, it likely doesn't have a "training set" in the sense of a machine learning algorithm. Its development would involve analytical studies and clinical performance validation, but the sample sizes for these are not detailed.

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

This information is not provided in the given 510(k) summary. If referring to the development and validation of the immunoassay, the ground truth would have been established through methods like "standard microscopic analysis (counting by Hemacytometer) based on WHO guidelines" for semen analysis samples, but the specifics of how this was applied for the device's development are not outlined.
