• Applicant: Zeus Scientific, Inc.
• Product Code: LFX · Microbiology
• Decision Date: Jul 20, 1999
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 866.3510
• Device Class: Class 2

Intended Use

The Rubella IgM ELISA test system is and enzyme-linked immunosorbent assay (ELISA) designed for the manual or automated (Aptus), qualitative determination of IgM-class antibody to rubelia virus in human serum. The test is intended to be used to evaluate serologic evidence of primary or active infection with Rubella and is for in vitro diagnostic use.

Device Story

The Aptus application is an automated processing system for the Rubella IgM ELISA test. It accepts human serum samples to detect IgM-class antibodies against the rubella virus. The device automates the enzyme-linked immunosorbent assay (ELISA) process, which is traditionally performed manually. It is intended for use in clinical laboratory settings by trained laboratory personnel. The system provides qualitative results that assist clinicians in diagnosing primary or active rubella infections. By automating the assay, the device aims to improve laboratory workflow efficiency and consistency in test performance compared to manual methods.

Clinical Evidence

No clinical data provided in the document; substantial equivalence is based on the performance of the automated application of the established Rubella IgM ELISA test system.

Technological Characteristics

Enzyme-linked immunosorbent assay (ELISA) for detection of IgM-class antibodies. The system supports both manual and automated (Aptus) processing. The device is an in vitro diagnostic test system.

Indications for Use

Indicated for qualitative determination of IgM-class antibodies to rubella virus in human serum to evaluate serologic evidence of primary or active rubella infection. For in vitro diagnostic use.

Regulatory Classification

Identification

Rubella virus serological reagents are devices that consist of antigens and antisera used in serological tests to identify antibodies to rubella virus in serum. The identification aids in the diagnosis of rubella (German measles) or confirmation of a person's immune status from past infections or immunizations and provides epidemiological information on German measles. Newborns infected in the uterus with rubella virus may be born with multiple congenital defects (rubella syndrome).

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 (OS) 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.
