Sigma Diagnostics ACCUCLOT™ CONTROL III is a human plasma control that is suitable for use as an abnormal control with patient citrated plasma in the one-stage prothrombin time (PT), in the activated partial thromboplastin time (APTT), the chromogenic Antithrombin III (AT-III) assay and in fibrinogen determinations using a clotting method. Plasma controls are routinely used in the coagulation laboratory as a means of quality control for coagulation testing

Sigma Diagnostics ACCUCLOT™ Control III is a lyophilized human plasma based product. After reconstitution with water, ACCUCLOT™ Control III is stable for 48 hours when stored at 2-8°C.

The provided text is a 510(k) summary for the Sigma Diagnostics ACCUCLOT™ Control III, which is a human plasma control. The document states that the safety and effectiveness of this device were demonstrated by its substantial equivalence to a legally marketed predicate device, the Sigma Diagnostics Coagulation Control, Level III (Cat. No. 9916).

Crucially, this document does not detail specific acceptance criteria for the ACCUCLOT™ Control III or a study with performance data against those criteria. Instead, it relies on the concept of substantial equivalence to an existing device.

Therefore, for many of your specific questions, the information is not available in the provided text, as the method of demonstrating effectiveness was comparative to a predicate, not through a study with pre-defined acceptance criteria and reported performance metrics.

Here is what can be extracted and what is not available based on the provided text:

1. Table of Acceptance Criteria and Reported Device Performance

Not available in the provided text. The submission relies on substantial equivalence to a predicate device rather than presenting specific acceptance criteria for the ACCUCLOT™ Control III and then reporting its performance against those criteria.

2. Sample Size Used for the Test Set and Data Provenance

Not available. No specific test set or study data is presented for the ACCUCLOT™ Control III. Its effectiveness is based on equivalence to the predicate device.

3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications

Not applicable/Not available. No specific test set requiring expert-established ground truth is described for the ACCUCLOT™ Control III.

4. Adjudication Method for the Test Set

Not applicable/Not available.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was Done

No. This type of study is typically for evaluating diagnostic imaging or interpretation systems with human readers. The ACCUCLOT™ Control III is a laboratory control, not a diagnostic imaging device.

6. If a Standalone (Algorithm Only Without Human-in-the-Loop Performance) was Done

Not available/Applicable in the way usually meant for devices with algorithms. The ACCUCLOT™ Control III is a laboratory quality control product, not an algorithmic diagnostic tool. Its performance is inherent in its chemical and biological properties when used in assays. The "standalone" performance would refer to its stability and performance in the coagulation assays, but specific data is not provided, only the claim of equivalence.

7. The Type of Ground Truth Used

The concept of "ground truth" as typically applied to diagnostic algorithms (e.g., pathology, outcomes data) does not directly apply here. For a quality control product, the "ground truth" in showing effectiveness is its ability to consistently yield expected results within specified ranges when used with reference methods, and its stability. However, explicit data on this for the ACCUCLOT™ Control III is not provided; rather, its equivalence to a predicate control is asserted.

8. The Sample Size for the Training Set

Not applicable/Not available. This device is a control material, not a machine learning algorithm that requires a training set.

9. How the Ground Truth for the Training Set was Established

Not applicable/Not available.
