Device Facts

• Record ID: K984181
• Device Name: THE APTUS (AUTOMATED) APPLICATION OF THE VZV IGG ELISA TEST SYSTEM
• Applicant: Zeus Scientific, Inc.
• Product Code: LFY · Microbiology
• Decision Date: Jan 22, 1999
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 866.3900
• Device Class: Class 2
• Attributes: Software as a Medical Device

Intended Use

The VZV IgG ELISA test system is and enzyme-linked immunosorbent assay (ELISA) designed for the manual or automated (Aptus), qualitative determination of IgG-class antibody to VZV in human serum. The test is intended to be used to aid in the determiation of immune status, and/or aid in the diagnosos of VZV infections, and is for in vitro diagnostic use.

Device Story

The Aptus application is an automated software module for the existing VZV IgG ELISA test system. It enables automated processing of ELISA plate data, replacing manual interpretation. Used in clinical laboratories by technicians; the system processes optical density measurements from ELISA plate readers. The software performs calculations to determine qualitative results (immune status/infection diagnosis) based on established ELISA thresholds. Output is provided to healthcare providers to assist in clinical decision-making regarding patient immunity or infection status. Benefits include increased efficiency and reduced manual error in laboratory testing workflows.

Clinical Evidence

No clinical data provided; substantial equivalence is based on analytical performance and technological characteristics of the automated application compared to the manual method.

Technological Characteristics

Automated software application for ELISA plate reader integration. Operates via standard ELISA optical density measurement principles. Designed for use with existing VZV IgG ELISA test system reagents.

Indications for Use

Indicated for qualitative determination of IgG-class antibodies to Varicella-Zoster Virus (VZV) in human serum to aid in immune status assessment and diagnosis of VZV infection. For in vitro diagnostic use.

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. 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.

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 [phone].

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 [phone]. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at [phone]. 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 [phone] or at [phone] or at its internet address "http://www.fda.gov/cdrh/dsmamain.html"
