The summary describes a standard coagulation testing system that measures clotting times based on physical properties of the blood sample. There is no mention of AI or ML in the device description, intended use, or any other section. The device functions based on established methods for measuring coagulation.
No.
The device is an in vitro diagnostic (IVD) system used to perform coagulation tests on blood samples, which provides information for diagnosis and monitoring, but does not directly treat or cure a disease or condition.
Yes
Explanation: The "Intended Use / Indications for Use" section explicitly states "For in vitro Diagnostic Use." The device performs point-of-care coagulation tests on whole blood, which are diagnostic procedures to assess a patient's clotting ability.
No
The device description clearly states it is a "battery-operated, hand-held instrument" with a "test chamber," "keypad," and "barcode scanner," indicating it is a hardware device that performs physical tests on blood samples. While it includes data management software, it is not solely software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Explicit Statement: The "Intended Use / Indications for Use" section explicitly states: "For in vitro Diagnostic Use."
- Nature of the Test: The device performs coagulation tests on whole blood, which is a biological sample taken from the body and tested in vitro (outside the body) to provide diagnostic information.
- Device Description: The description details how the device interacts with a test cuvette containing a blood sample to measure clotting time, which is a classic example of an in vitro diagnostic process.
Therefore, based on the provided information, the Hemochron™ Signature Elite Whole Blood Microcoagulation System is clearly an In Vitro Diagnostic device.

Device Description
The Hemochron™ Signature Elite Whole Blood Microcoagulation System is a battery operated hand-held instrument. The system is intended for use in clinical settings requiring point of care testing. Whole blood test results are displayed as clotting times (in seconds). The instrument also displays correlated Celite® equivalent ACT values, APTT and PT plasma equivalent values, and the PT INR value.
The Hemochron™ Signature Elite Whole Blood Microcoagulation System contains a test chamber which warms a test cuvette to the required temperature, and it performs all operations to measure the clotting time of a whole blood sample after it is placed in the test cuvette and the test is started by the operator. The front panel contains a keypad with various action keys as well as a number pad. The operator uses the keypad to select a command or enter information. The instrument also includes a barcode scanner for reading of barcode identifications (IDs).
Data management capabilities are included with the instrument. These capabilities include storage of up to 600 patient results and 600 quality control results, designation of quality control levels, tagging of test results with date and time, entry of Patient ID and/or Operator ID or Operator PIN and printing of results

Dear Brian James:
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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. 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
1
