Intended Use
The KRONUS Voltage Gated Calcium Channel (VGCC) Antibody RIA Assay Kit is for the semiquantitative determination of antibodies to voltage gated calcium channels in human serum. The VGCC antibody may be present in patients diagnosed with Lambert-Eaton Myasthenic Syndrome (LEMS). The assay result is not to be used alone and is to be used in conjunction with other clinical, electrodiagnostic and laboratory findings.
Device Story
The KRONUS VGCC Antibody RIA Assay Kit is an in vitro diagnostic test used to detect autoantibodies against voltage-gated calcium channels in human serum. The device utilizes a radioimmunoassay (RIA) principle; patient serum is incubated with 125I-labeled VGCC antigen; antibody-antigen complexes are precipitated; radioactivity is measured to determine antibody levels. The assay is performed in a clinical laboratory setting by trained laboratory personnel. Results are provided to clinicians to assist in the diagnosis of Lambert-Eaton Myasthenic Syndrome (LEMS). The output is a semiquantitative measurement of antibody concentration, which must be interpreted alongside clinical symptoms, electrodiagnostic testing, and other laboratory data to support a clinical diagnosis.
Clinical Evidence
No clinical data provided; substantial equivalence is based on analytical performance and comparison to the predicate device.
Technological Characteristics
Radioimmunoassay (RIA) kit; utilizes 125I-labeled VGCC antigen; semiquantitative measurement of autoantibodies in human serum; manual laboratory procedure; requires gamma counter for signal detection.
Indications for Use
Indicated for semiquantitative determination of VGCC antibodies in human serum for patients diagnosed with or suspected of having Lambert-Eaton Myasthenic Syndrome (LEMS). Not for use as a standalone diagnostic; must be used with clinical, electrodiagnostic, and other laboratory findings.
Regulatory Classification
Identification
A multiple autoantibodies immunological test system is a device that consists of the reagents used to measure by immunochemical techniques the autoantibodies (antibodies produced against the body's own tissues) in serum and other body fluids. Measurement of multiple autoantibodies aids in the diagnosis of autoimmune disorders (disease produced when the body's own tissues are injured by autoantibodies).

Dear Ms. Viele:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and 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) that do not require approval of a premarket approval application (PMA). 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 class II (Special Controls), it may be subject to such additional controls. Existing major regulations affecting your device can be found in Title 21, Code of Federal Regulations (CFR), Parts 800 to 895. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Parts 801 and 809); medical device reporting (reporting of medical device-related adverse events) (21 CFR 803); and good manufacturing practice

requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820). This letter will allow you to begin marketing your device as described in your Section 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 Parts 801 and 809), please contact the Office of In Vitro Diagnostic Device Evaluation and Safety at (301) 796-5450. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to http://www.fda.gov/MedicalDevices/Safety/ReportaProblem/default.htm for the CDRH's Office of Surveillance and Biometrics/Division of Postmarket Surveillance.
You may obtain other general information on your responsibilities under the Act from the Division of Small Manufacturers, International and Consumer Assistance at its toll-free number (800) 638-2041 or (301) 796-7100 or at its Internet address http://www.fda.gov/cdrh/industry/support/index.html.
