The provided text is a 510(k) clearance letter from the FDA for an in vitro diagnostic device (VITROS Immunodiagnostic Products CK-MB Reagent Pack, Calibrators, and Controls). This type of document does not contain the detailed study information required to answer your questions about acceptance criteria, performance, sample sizes, ground truth establishment, or expert involvement.
The FDA 510(k) clearance process focuses on demonstrating substantial equivalence to a legally marketed predicate device, rather than requiring detailed de novo clinical study results in the same way a PMA (Premarket Approval) would. While the applicant would have submitted data to the FDA, that data isn't typically included in the public-facing clearance letter.
Therefore, I cannot provide the requested information from the given text. To get this data, you would typically need to refer to the 510(k) summary document (which often contains a condensed version of the performance data) or the full 510(k) submission itself, which is usually not publicly accessible in its entirety.
In summary, the provided document does not contain the information needed to fill out the requested table or answer the specific questions about the study design and results.
§ 862.1660 Quality control material (assayed and unassayed).
(a)
Identification. A quality control material (assayed and unassayed) for clinical chemistry is a device intended for medical purposes for use in a test system to estimate test precision and to detect systematic analytical deviations that may arise from reagent or analytical instrument variation. A quality control material (assayed and unassayed) may be used for proficiency testing in interlaboratory surveys. This generic type of device includes controls (assayed and unassayed) for blood gases, electrolytes, enzymes, multianalytes (all kinds), single (specified) analytes, or urinalysis controls.(b)
Classification. Class I (general controls). Except when intended for use in donor screening tests, quality control materials (assayed and unassayed) are exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 862.9.
