Not Found
The provided text is an FDA 510(k) clearance letter for the BioCheck Total T4 Enzyme Immunoassay Test Kit. It primarily focuses on the regulatory approval and indications for use. It does not contain the specific details about the acceptance criteria or the study that proves the device meets those criteria, as typically found in a clinical study report or a more detailed technical submission.
Therefore, I cannot provide the requested information from the given text.
In general, for a medical device seeking regulatory clearance, a submission would include:
- Acceptance Criteria: Predetermined performance thresholds the device must meet (e.g., sensitivity, specificity, accuracy, precision, linearity, stability) compared to a predicate device or a gold standard.
- Study Design and Results: Detailed descriptions of the studies conducted to demonstrate that the device meets these criteria. This would typically include:
- Sample Size: Number of patients or samples used in the study.
- Data Provenance: Where the data came from (e.g., specific hospitals, geographical regions) and whether it was retrospective or prospective.
- Ground Truth Establishment: How the true status (e.g., presence or absence of a disease) was determined. For diagnostic tests, this might involve confirmed clinical diagnosis, pathology, or expert consensus.
- Expert Qualifications: If experts were used, their experience and specialization.
- Adjudication Method: How disagreements among experts were resolved.
- MRMC Study: If applicable, to assess reader performance with and without the device.
- Standalone Performance: The algorithm's performance without human intervention.
- Training Set Details: Information about the data used to train any AI or algorithm component, including size and ground truth establishment.
Since this information is not in the provided document, I cannot fill out the requested table or answer the specific questions.

Dear Ms. Hellen:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
Image /page/0/Picture/9 description: The image shows a circular logo for the Department of Health & Human Services (HHS) in the USA. The logo features the HHS symbol, which consists of three stylized human figures connected by flowing lines, representing the department's mission to protect the health of all Americans and provide essential human services. The text "DEPARTMENT OF HEALTH & HUMAN SERVICES - USA" is arranged around the upper portion of the circle.

Under the Clinical Laboratory Improvement Amendments of 1988 (CLIA-88), this device may require a CLIA complexity categorization. To determine if it does, you should contact the Centers for Disease Control and Prevention (CDC) at (770) 488-7655.
This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at (301) 594-4588. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639. Also, please note the regulation entitled, "Misbranding by reference to premarket notification"(21 CFR 807.97). Other general information on your responsibilities under the Act may be obtained from the Division of Small Manufacturers Assistance at its toll-free number (800) 638-2041 or (301) 443-6597, or at its internet address "http://www.fda.gov/cdrh/dsma/dsmamain.html".
