HemosIL PT-Fibrinogen HS PLUS is a very high sensitivity calcium thromboplastin for simultaneous determinations of Prothrombin Time (PT) and Fibrinogen (Fib), for evaluation of the extrinsic coagulation pathway and monitoring Oral Anticoagulant Therapy in human citrated plasma on the IL Coagulation Systems. For in vitro diagnostic use.

Device Description

HemosIL PT-Fibrinogen HS PLUS is a very high sensitivity calcium thromboplastin for simultaneous determinations of Prothrombin Time (PT) and Fibrinogen (Fib), for evaluation of the extrinsic coagulation pathway and monitoring Oral Anticoagulant Therapy in human citrated plasma on the IL Coagulation Systems.

AI/ML Overview

Here's an analysis of the provided text regarding the HemosIL PT-Fibrinogen HS PLUS device, broken down by your requested criteria:

1. Table of Acceptance Criteria and Reported Device Performance

AssaySystemAcceptance Criteria (Range - units)Reported Device Performance (Range - units)
PTACL Futura/ACL AdvanceNot explicitly stated as "acceptance criteria," but implied as the target normal range update for the device.11.1 - 14.5 (seconds)
FibrinogenACL Futura/ACL AdvanceNot explicitly stated as "acceptance criteria," but implied as the target normal range update for the device.262 - 433 (mg/dL)

Note: The document presents the "new expected values data" as the outcome of the study, rather than pre-defined acceptance criteria. The purpose of this submission was to update these expected values based on new data, implying that the study's success was determined by the derivation of these new ranges.

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

  • Test Set Sample Size: 119
  • Data Provenance: Not explicitly stated within the document for country of origin. The study was conducted to establish "new normal range study," implying it was a prospective study to determine reference ranges from a healthy population.

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

This document does not describe the use of "experts" for establishing ground truth in the context of interpreting the results. The "ground truth" here is the measured PT and Fibrinogen values from the healthy individuals in the normal range study. The device itself performs the measurement.

4. Adjudication Method for the Test Set

Not applicable. The study is establishing reference ranges for a quantitative diagnostic test, not interpreting complex medical images or information requiring adjudication.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

No. This document describes a normal range study for a quantitative diagnostic assay, not a comparative effectiveness study involving human readers.

6. Standalone Performance Study

Yes, in a sense. The data presented are from the device (HemosIL PT-Fibrinogen HS PLUS on ACL Futura/ACL Advance systems) measuring PT and Fibrinogen in human plasma. This is a standalone performance of the algorithm/reagent system as it's designed to operate for in vitro diagnostic use. The study focuses on the values obtained by the device itself.

7. Type of Ground Truth Used

The "ground truth" in this context is the measured Prothrombin Time and Fibrinogen values obtained from a population of apparently healthy individuals. It's essentially the observed data from the device itself when run on a specific population to define normal ranges.

8. Sample Size for the Training Set

Not mentioned. This document describes a study to establish reference ranges for the device, not a machine learning model that would require a separate training set. The normal range study sample of 119 individuals could be considered the "data" from which the expected values were derived.

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

Not applicable for a typical machine learning "training set" as described in the prompt. For the normal range study, the "ground truth" (the observed PT and Fibrinogen values) was established by running the HemosIL PT-Fibrinogen HS PLUS on the ACL Futura/ACL Advance systems with human citrated plasma from the 119 individuals in the study. The definition of a "normal" range is statistical, based on the distribution of these measured values within that population.

Identification of Predicate Device(s):

K933252 HemosIL PT-Fibrinogen HS PLUS

Device Description:

HemosIL PT-Fibrinogen HS PLUS is a very high sensitivity calcium thromboplastin for simultaneous determinations of Prothrombin Time (PT) and Fibrinogen (Fib), for evaluation of the extrinsic coagulation pathway and monitoring Oral Anticoagulant Therapy in human citrated plasma on the IL Coagulation Systems.

Reason for Submission:

The expected value ranges for PT and Fibrinogen on the ACL Futura/ACL Advance provided in the product insert for HemosIL PT-Fibrinogen HS PLUS are being updated based on data from a new normal range study.

Statement of Technological Characteristics of the Device Compared to Predicate Device:

The performance of HemosIL PT-Fibrinogen HS PLUS with the new expected value ranges for the ACL Futura and ACL Advance is not materially different from the FDA cleared device.

Summary of New Expected Values Data:

AssaySystemNRange (units)
PTACL Futura/ACL Advance11911.1 - 14.5 (seconds)
FibrinogenACL Futura/ACL Advance119262 - 433 (mg/dL)

These results were obtained using a specific lot of reagent. Due to the many variables which may affect clotting times, each laboratory should establish its own reference range.

Dear Ms. Marble:

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.
