The summary describes a standard enzyme immunoassay (ELISA) for detecting a specific protein. There is no mention of AI, ML, or any related computational techniques.
No
This device is an immunoassay for detecting activated factor XII in human plasma, which is a diagnostic test, not a therapeutic intervention.
Yes
The device is described as an assay for the detection of activated factor XII (FXIIa) in human citrated plasma, which "may be used as an index of activation of the contact (intrinsic) system of coagulation." This directly indicates its use in identifying a biological marker related to a physiological process, fitting the definition of a diagnostic device.
No
The device description clearly states it is an "ELISA TEST," which is a laboratory assay involving physical reagents and equipment, not solely software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states that the assay is for the "detection, in human citrated plasma, of activated factor X11". This involves testing a sample taken from the human body (plasma) outside of the body (in vitro) to provide information about a physiological state (activation of the contact system of coagulation).
- Device Description: The device is described as an "ACTIVATED FACTOR X11 (FX11a) ELISA TEST". ELISA (Enzyme-Linked Immunosorbent Assay) is a common technique used in in vitro diagnostics to detect and quantify substances in biological samples.
These points clearly align with the definition of an In Vitro Diagnostic device.
N/A
Intended Use / Indications for Use
The Shield Activated Factor XII (FXIIa) assay is a semi-quantitative direct enzyme immunoassay for the detection, in human citrated plasma, of activated factor XII (α-FXIIa and β-FXIIa). The test may be used as an index of activation of the contact (intrinsic) system of coagulation.

§ 864.7290 Factor deficiency test.
(a)
Identification. A factor deficiency test is a device used to diagnose specific coagulation defects, to monitor certain types of therapy, to detect coagulation inhibitors, and to detect a carrier state (a person carrying both a recessive gene for a coagulation factor deficiency such as hemophilia and the corresponding normal gene).(b)
Classification. Class II (performance standards).

Dear Ms. McCafferty:
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 leqally 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 Reqister. 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.

This letter will allow you to begin marketing your device as described in your 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.
If you desire specific advice for your device on our labeling requlation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at (301) 594-4588. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639. Also, please note the requlation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97). Other general information on your responsibilities under the Act may be obtained from the Division of Small Manufacturers Assistance at its toll-free number (800) 638-2041 or (301) 443-6597, or at its internet address "http://www.fda.qov/cdrh/dsma/dsmamain.html".
