For use as a quality control plasma to monitor the precision of laboratory testing procedures for the analytes listed in this package in on the
Lyphochek® Hemostasis Control is prepared from human plasma with added purified biochemicals and preservatives. The control is provided in lyophilized form for increased stability.
The provided document describes the Lyphochek® Hemostasis Control, a quality control plasma. It does not describe an AI medical device or a study comparing AI performance against human performance. Therefore, I cannot provide information on acceptance criteria, sample sizes for test/training sets, expert qualifications, adjudication methods, MRMC studies, or standalone algorithm performance as these are not relevant to the given document.
The document focuses on demonstrating substantial equivalence to a predicate device (K020878) based on similarities in intended use, form, matrix, storage, and reconstituted stability claims, and verifying the stability of the new device for the specified analytes.
Here is the information that can be extracted from the provided text regarding the Lyphochek® Hemostasis Control:
1. Table of Acceptance Criteria and Reported Device Performance
The document does not explicitly state "acceptance criteria" in the traditional sense of a performance study for an AI device. Instead, it details product claims related to stability, which are effectively the performance characteristics that the device is intended to meet.
| Performance Characteristic | Acceptance Criteria (Product Claim) | Reported Device Performance |
|---|---|---|
| Reconstituted Stability | All analytes stable for 8 hours at 2-25°C. Exception: Protein S stable for 8 hours at 2-8°C. | Product claims states these conditions are met. |
| Shelf Life | Three years when stored at 2-8°C. | Product claims states this condition is met. |
| Ongoing Studies | Real-time studies will be ongoing to support the shelf life of this product. | Confirmed that studies are ongoing to support the shelf life. |
| Analytes Included | Prothrombin Time (PT), Activated Partial Thromboplastin Time (APTT), Fibrinogen, Antithrombin III (AT III) Thrombin Time (TT), Factor II, V, VII, VIII, IX, X, XI, XII, Protein S (Functional) Protein C (Functional), Plasminogen, and D-dimer. | The device contains all listed analytes. |
2. Sample Size Used for the Test Set and Data Provenance
The document does not mention a "test set" or provide specific sample sizes for stability studies. It states that "All supporting data is retained on file at Bio-Rad Laboratories," indicating that data exists but is not elaborated upon in the summary. Data provenance (country of origin, retrospective/prospective) is not mentioned.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications
Not applicable. This device is a quality control material, not an AI diagnostic device requiring expert interpretation for ground truth establishment.
4. Adjudication Method for the Test Set
Not applicable. This device is a quality control material.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done
No. This is not an AI diagnostic device designed to be used by human readers, so an MRMC study comparing human readers with and without AI assistance is not relevant.
6. If a Standalone (i.e. algorithm only without human-in-the loop performance) Was Done
No. This is not an AI algorithm.
7. The Type of Ground Truth Used
For a quality control product, the "ground truth" would be the assayed target values of the analytes within the control material, established through precise analytical methods and often an internal reference measurement system. The document does not specify how these target values were established.
8. The Sample Size for the Training Set
Not applicable. This is not an AI algorithm requiring a training set.
9. How the Ground Truth for the Training Set Was Established
Not applicable. This is not an AI algorithm.

Dear Ms. Platt:
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 concerning 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); and good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820). This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
