The Randox Laboratories Ltd. Immunoassay Controls (Levels I, II, and III) are based on lyophilised human serum and have been developed for the control of both accuracy and precision in a wide range of laboratory applications, particularly Immunoassay analysis. The product is available at three constituent concentrations. Each level is available in a 5ml final re-constituted volume. The Randox Assayed Immunoassay Controls should only be used by suitably qualified laboratory personnel under appropriate laboratory conditions.

The provided text is a 510(k) clearance letter from the FDA for "Assayed Immunoassay Controls" from Randox Laboratories Ltd. This document does not describe acceptance criteria or a study proving device performance as typically expected for an AI/ML or imaging device. Instead, it is a regulatory document confirming substantial equivalence of a quality control material to a predicate device.
Therefore, I cannot extract the requested information as it is not present in the provided text. The device in question is a laboratory quality control material, not a device that would typically undergo the kind of performance studies involving AI, human readers, or ground truth establishment that your questions imply.
§ 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.
