Not Found

No
The summary describes a standard enzyme immunoassay (EIA) for detecting antibodies. There is no mention of AI, ML, or any computational methods that would suggest their use in the device's operation or interpretation. The performance studies are based on direct comparison to a predicate device and standard statistical metrics.

No.
The device is for in vitro diagnostic use, specifically for detecting antibodies to aid in differentiating active/recent infection from past infection, not for treating a condition.

Yes

The first point under "Intended Use / Indications for Use" explicitly states: "1. For in vitro diagnostic use only."

No

The device description clearly states it is a solid-phase enzyme immunoassay (EIA) performed in microwells, indicating a physical kit with reagents and a testing procedure, not a software-only device.

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

Here's why:

  • Explicit Statement: The very first point under "Intended Use / Indications for Use" is "For in vitro diagnostic use only." This is a clear and direct statement of its intended purpose.
  • Nature of the Test: The device performs a test on human serum (a biological sample taken from the body) to detect antibodies. This is a classic example of an in vitro diagnostic test, as it's performed outside of the living organism.
  • Purpose of the Test: The test is used as an "aid in differentiating active or recent infection, from past infection." This indicates that the results are intended to provide information for a medical diagnosis or to aid in making a clinical decision.

The other sections of the document further support this:

  • Device Description: Describes a "solid-phase enzyme immunoassay (EIA)" performed in microwells, which is a common method for in vitro diagnostic tests.
  • Intended User / Care Setting: While it mentions manual use or use with a specific system, the overall context is for diagnostic use.
  • Performance Studies and Key Metrics: The inclusion of clinical testing data, sensitivity, specificity, and overall agreement are all standard elements of documentation for an IVD device, demonstrating its performance in a diagnostic context.
  • Predicate Device: The comparison to another EBV IgG ELISA test (Gull Laboratories') further confirms its place within the realm of in vitro diagnostics.

Therefore, based on the provided information, the SeraQuest EB VCA IgG test is clearly an In Vitro Diagnostic device.

Identification. Epstein-Barr virus serological reagents are devices that consist of antigens and antisera used in serological tests to identify antibodies to Epstein-Barr virus in serum. The identification aids in the diagnosis of Epstein-Barr virus infections and provides epidemiological information on diseases caused by these viruses.

Dear Mr. Cort:

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 datc 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 rcquirements, 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 Eederal 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.

Under the Clinical Laboratory Improvement Amendments of 1988 (CLIA-88), this device may require a CLIA complexity categorization. To determine if it does, you should contact the Centers for Disease Control and Prevention (CDC) at (770)488-7655.

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 regulation (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 regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97).
