No
The description details a mechanical and optical process for detecting clot formation based on blood flow, with electronic correction for lot variability. There is no mention of AI or ML algorithms for data analysis, interpretation, or decision-making.
No
The device is used for the quantitative determination of activated partial thromboplastin time (APTT) in whole blood, which is a diagnostic measurement to evaluate intrinsic pathway function and monitor the effectiveness of heparin therapy, not to treat a condition.
Yes
The device quantitatively determines activated partial thromboplastin time (APTT) to evaluate intrinsic pathway function and monitor heparin therapy, which are diagnostic purposes.
No
The device description clearly details a physical instrument, test cartridges, and a laser optical system, indicating it is a hardware-based medical device that utilizes software for processing and displaying results, but is not solely software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states it's for the "quantitative determination of the activated partical thromboplastin time (APTT) of freshly drawn whole blood." This is a test performed on a biological sample (whole blood) outside of the body to provide information about a patient's health status (coagulation function).
- Device Description: The description details how the device analyzes a blood sample using reagents and a detection system to measure the time it takes for a clot to form. This process is characteristic of an in vitro diagnostic test.
- Sample Type: The device uses "freshly drawn whole blood," which is a biological specimen.
- Purpose: The purpose is to evaluate "intrinsic pathway function," screen for "coagulation function," and "monitor the effectiveness of heparin therapy." These are all diagnostic purposes.
The definition of an IVD is a medical device that is used to perform tests on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. This device clearly fits that definition.

Device Description
The APTT is used to evaluate intrinsic pathway function. The APTT is sensitive to deficiencies of factors VIII, IX, XI, and XII, prekallikrein, high molecular weight kinogen, as well as common pathway factors (II, V, X, and fibrinogen). The APTT is useful as a screening test for coagulation function, since it is sensitive to all coagulation factors except VII, platelet factor III and calcium. Additionally, the APTT is used to monitor the effectiveness of heparin therapy. Many diseases and drugs can prolong or prevent coagulation by altering the balance of clotting factors involved in coagulation. The APTT test is initiated by inserting a CoaguChek Pro APTT test cartridge into the instrument. The instrument reads a code on the test cartridge to determine test identity and lot number. The test cartridge contains a sample application well, a reagent chamber, and a reaction path. After the instrument heats the test cartridge, a drop of fresh, whole blood is placed on the test cartridge sample application well. Blood is drawn into the reagent chamber by capillary action, where it mixes with the reagent to initiate coagulation. The blood sample moves along the reaction path until a clot forms. The laser optical system detects the clot by monitoring blood flow; endpoint is reached when the blood stops moving. The time from sample application to clot detection is the APTT. The displayed result is equivalent to laboratory plasma APTT results. Because each newly-manufactured lot is calibrated to an internal reference lot, any lot-to-lot variability between reagents is corrected electronically using information coded on the lot-specific code key.

Dear Ms. Ochs:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we 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). 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 (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
