This document is a 510(k) premarket notification decision letter from the FDA regarding the Olympus FT4 Free thyroxine and Olympus T4 Total thyroxine test systems. It does not contain the specific details about acceptance criteria, device performance, study design, or ground truth establishment that you are requesting.
The letter primarily states that the devices are substantially equivalent to legally marketed predicate devices and can therefore be marketed. It outlines regulatory requirements but does not delve into the technical validation studies.
To answer your questions, you would need to refer to the actual 510(k) premarket notification submission itself, which typically includes detailed study reports, performance data, and other validation information. This letter only provides the FDA's decision based on that submission.
§ 862.1695 Free thyroxine test system.
(a)
Identification. A free thyroxine test system is a device intended to measure free (not protein bound) thyroxine (thyroid hormone) in serum or plasma. Levels of free thyroxine in plasma are thought to reflect the amount of thyroxine hormone available to the cells and may therefore determine the clinical metabolic status of thyroxine. Measurements obtained by this device are used in the diagnosis and treatment of thyroid diseases.(b)
Classification. Class II.
