The LOCI THYR CAL is an in vitro diagnostic product for the calibration of the LOCI Free Triiodothyronine (FT3), LOCI Free Thyroxine (FT4L) and LOCI Thyroid Stimulating Hormone (TSHL) methods on the Dimension® EXL™ integrated chemistry system with LOCI® Module.

Device Description

The LOCITHYR CAL is a multi-analyte, liquid, bovine serum albumin based product containing triiodothyronine, thyroxine and human thyroid stimulating hormone. The kit consists of ten vials with two vials per level containing 2.0 mL per vial.

AI/ML Overview

The provided text describes a 510(k) summary for the LOCI Thyroid Calibrator, focusing on its substantial equivalence to a predicate device. However, it does not contain information about acceptance criteria, device performance studies, sample sizes, expert involvement, or ground truth establishment.

Therefore, I cannot fulfill your request for a table of acceptance criteria and reported device performance, nor can I provide details about the study that proves the device meets acceptance criteria based only on the provided input.

The document primarily states:

The device is a calibrator for specific thyroid hormone tests.
It is substantially equivalent to a previously cleared device (K073604).
The key difference from the predicate is the addition of calibration for "Free Triiodothyronine (FT3)".

To answer your request thoroughly, I would need a different type of document, such as a full. 510(k) submission, a clinical study report, or a validation study report that details performance characteristics and acceptance criteria.

Dear Ms. Marinelli:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and 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) that do not require approval of a premarket approval application (PMA). 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 (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in Title 21, Code of Federal Regulations (CFR), Parts 800 to 895. In addition, FDA may publish further announcements concérning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Parts 801 and 809); medical device reporting (reporting of medical device-related adverse events) (21 CFR 803); and good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820).
