## Indications for Use

This test system is designed for the manual or automated, qualitative detection of IgG antibodies to HSV-2 in human serum. The test system is intended to be used to evaluate serologic evidence of primary or reactivated infection with HSV. Due to cross reactivity of shared antigens, the HSV-1 IgG ELISA test should be performed in conjunction with this test system to fully evaluate the patient serum. The test is for in vitro diagnostic use.

## Device Story

The Aptus (automated) Application for the HSV-2 IgG ELISA Test is an in vitro diagnostic system designed for clinical laboratory use. It detects IgG antibodies to HSV-2 in human serum samples. The system supports both manual and automated processing of the ELISA (Enzyme-Linked Immunosorbent Assay) test. By identifying specific IgG antibodies, the device assists clinicians in evaluating patients for primary or reactivated HSV infection. Because HSV-1 and HSV-2 share antigens, the device output must be interpreted alongside results from an HSV-1 IgG ELISA test to ensure accurate serologic evaluation. The system provides qualitative results that inform clinical decision-making regarding HSV infection status.

## Clinical Evidence

No clinical data provided in the document; bench testing only.

## Technological Characteristics

In vitro diagnostic ELISA test system for qualitative detection of IgG antibodies. Supports manual or automated processing. Operates via immunological binding principles. No specific materials, energy sources, or software algorithm details provided.

## Regulatory Identification

Herpes simplex virus serological assays are devices that consist of antigens and antisera used in various serological tests to identify antibodies to herpes simplex virus in serum. Additionally, some of the assays consist of herpes simplex virus antisera conjugated with a fluorescent dye (immunofluorescent assays) used to identify herpes simplex virus directly from clinical specimens or tissue culture isolates derived from clinical specimens. The identification aids in the diagnosis of diseases caused by herpes simplex viruses and provides epidemiological information on these diseases. Herpes simplex viral infections range from common and mild lesions of the skin and mucous membranes to a severe form of encephalitis (inflammation of the brain). Neonatal herpes virus infections range from a mild infection to a severe generalized disease with a fatal outcome.

## Special Controls

*Classification.* Class II (special controls). The device is classified as class II (special controls). The special control for the device is FDA's revised guidance document entitled “Class II Special Controls Guidance Document: Herpes Simplex Virus Types 1 and 2 Serological Assays.” For availability of the guidance revised document, see § 866.1(e).

Dear Mr. Kopnitsky:

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.

Image /page/0/Picture/9 description: The image shows the logo for the U.S. Department of Health and Human Services. The logo consists of a stylized eagle with three human profiles incorporated into its design. The eagle is enclosed within a circle, and the text "DEPARTMENT OF HEALTH & HUMAN SERVICES • USA" is arranged around the circle's perimeter.

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). 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 at (301) 443-6597 or at its internet address "http://www.fda.gov/cdrh/dsmamain.html"
