Indications for Use

For in vitro diagnostic use only. For the qualitative and semi-quantitative detection of IgG antibodies to varicella zoster virus (VZV) in human serum by enzyme immunoassay. Individual specimens may be used for the determination of immune status. Paired (acute / convalescent) sera, may be used to demonstrate seroconversion or significant rises in antibody level, as an aid in the diagnosis of primary infection, or reactivation of VZV. For manual use, or for use with the HyPrep System Plus semi-automated fluid handler.

Device Story

SeraQuest VZV IgG is an enzyme immunoassay (EIA) for detecting IgG antibodies to varicella zoster virus in human serum. The device processes serum samples to identify immune status or seroconversion/antibody titer increases indicative of VZV infection or reactivation. It is designed for manual laboratory use or integration with the HyPrep System Plus semi-automated fluid handler. Healthcare providers use the qualitative or semi-quantitative results to assess patient immunity or confirm clinical suspicion of VZV infection, facilitating appropriate patient management and diagnostic decision-making.

Clinical Evidence

No clinical data provided in the document.

Technological Characteristics

Enzyme immunoassay (EIA) for antibody detection. Compatible with manual processing or the HyPrep System Plus semi-automated fluid handler. In vitro diagnostic device.

Indications for Use

Indicated for qualitative and semi-quantitative detection of IgG antibodies to varicella zoster virus (VZV) in human serum. Used for determining immune status and as an aid in diagnosing primary infection or reactivation of VZV via paired acute/convalescent sera analysis.

Regulatory Classification

Identification

Varicella-zoster virus serological reagents are devices that consist of antigens and antisera used in serological tests to identify antibodies to varicella-zoster in serum. The identification aids in the diagnosis of diseases caused by varicella-zoster viruses and provides epidemiological information on these diseases. Varicella (chicken pox) is a mild, highly infectious disease, chiefly of children. Zoster (shingles) is the recurrent form of the disease, occurring in adults who were previously infected with varicella-zoster viruses. Zoster is the response (characterized by a rash) of the partially immune host to a reactivation of varicella viruses present in latent form in the patient's body.

Dear Mr. Cort:

Re:

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 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 requirement, 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.
