More Information

Not Found

No
The document describes an in vitro diagnostic device for detecting lupus anticoagulants using a specific chemical method (dilute Russell's viper venom) and does not mention any AI or ML components.

No
The device is an in vitro diagnostic (IVD) test used to detect lupus anticoagulants in plasma. It is not used to treat, cure, mitigate, or prevent disease, which are characteristics of a therapeutic device.

Yes
The "Intended Use / Indications for Use" states that the kits are "intended for the detection of lupus anticoagulants (LA) in plasma," which is a diagnostic purpose. The "Device Description" also refers to it as an "in vitro diagnostic device."

No

The device description explicitly states it is an "in vitro diagnostic device" and refers to "kits" and "reagents" used with "analyzers." This indicates a physical, hardware-based system, not a software-only device.

Yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The "Intended Use / Indications for Use" section explicitly states that the kits are "intended for the detection of lupus anticoagulants (LA) in plasma". This describes a test performed on a sample taken from the body (plasma) to provide information about a medical condition (lupus anticoagulants).
  • Device Description: The "Device Description" section refers to the device as an "in vitro diagnostic device".
  • Performance Studies: The performance studies involve testing "plasmas obtained from patients", which is characteristic of an in vitro diagnostic test.

These points clearly indicate that the device is designed to be used outside of the body to examine samples for diagnostic purposes, which is the definition of an In Vitro Diagnostic device.

Dear Dr. Worfolk:

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.
