CareStart™ Pregnancy Test is intended for the qualitative detection of human chorionic gonadotropin (hCG) in urine for the early detection of pregnancy. The test is intended for over-the counter sale to laypersons.

Not Found

The provided text is a 510(k) clearance letter for the CareStart™ Pregnancy Test and CareStart PLUS™ Pregnancy Test. It states that the device is substantially equivalent to legally marketed predicate devices. However, this document does not contain the detailed study information, acceptance criteria, or performance data typically found in a clinical study report or a more comprehensive summary of safety and effectiveness (SSE).

Therefore, based solely on the provided text, I cannot complete a table of acceptance criteria and reported device performance, nor can I answer many of the specific questions about the study design, sample sizes, ground truth establishment, or expert qualifications.

The only information directly related to performance from this document is:

• Intended Use: Qualitative detection of human chorionic gonadotropin (hCG) in urine for the early detection of pregnancy.
• Target User: Laypersons (over-the-counter sale).

To fully answer your request, a more detailed document, such as a 510(k) summary (which often contains safety and effectiveness data), would be required.

Based on the provided text, here's what can and cannot be answered:

1. A table of acceptance criteria and the reported device performance:

• Cannot be provided as this information is not in the clearance letter. Acceptance criteria and specific performance metrics (like sensitivity and specificity at various hCG levels) are typically found in the clinical study report or 510(k) summary, not the clearance letter itself.

2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective):

• Cannot be provided as this information is not in the clearance letter.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience):

• Cannot be provided as this information is not in the clearance letter. (For a pregnancy test, ground truth would likely be established by a reference method measuring hCG levels, not typically by expert interpretation of the test result itself in a clinical study context for regulatory submission.)

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:

• Cannot be provided as this information is not in the clearance letter.

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:

• Not applicable. This device is a rapid diagnostic test (pregnancy test), not an AI-assisted diagnostic imaging device or an AI application that would be used by human readers in an MRMC study.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

• Not applicable. This device is a rapid diagnostic test that provides a visual result for the user. It is inherently "standalone" in that it performs its function without a separate algorithm needing to be assessed for standalone performance. The "human-in-the-loop" here is the layperson interpreting the visual result.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):

• Cannot be definitively stated from this document. For a pregnancy test, the ground truth for establishing performance is almost always a quantitative laboratory method (e.g., ELISA, RIA, or other highly sensitive and specific quantitative hCG assays) that measures the actual concentration of hCG in urine or serum, rather than expert consensus, pathology, or outcomes data.

8. The sample size for the training set:

• Cannot be provided as this information is not in the clearance letter.

9. How the ground truth for the training set was established:

• Cannot be provided as this information is not in the clearance letter. (As mentioned above, for pregnancy tests, it's typically based on quantitative laboratory hCG measurements.)
