No
The document describes a linearity set for a chemical test, with no mention of AI or ML.

No
The device is described as a "Linearity Set" used for the "estimation of the linearity limits of the reagent/instrument system for the CH50 analyte," which indicates it is a calibration or quality control tool for an assay, not a device used for treating a medical condition.

No

Explanation: The device, the "CH50 Linearity Set," is described as being used with a test for the "estimation of the linearity limits of the reagent/instrument system for the CH50 analyte." This indicates it is a quality control or calibration tool for an assay, rather than a device that directly diagnoses a patient's condition.

No

The summary describes a "Linearity Set" used with a "test" and "reagent/instrument system." This strongly suggests a physical kit or set of materials used in a laboratory setting, not a software-only device. The lack of any mention of software, algorithms, or digital processing further supports this conclusion.

Based on the provided information, the CH50 Linearity Set is likely an IVD (In Vitro Diagnostic) device.

Here's why:

  • Intended Use: The intended use explicitly states it's to be used with the "WAKO Autokit CH50 test" for "estimation of the linearity limits of the reagent/instrument system for the CH50 analyte." This indicates it's a component used in a laboratory setting to evaluate the performance of a diagnostic test (the WAKO Autokit CH50 test).
  • Function: Linearity sets are typically used to verify that a diagnostic test provides accurate results across a range of analyte concentrations. This is a crucial quality control step in in vitro diagnostics.

While the "Device Description" is not found, the intended use strongly suggests its role in the performance evaluation of an in vitro diagnostic test. Devices used for quality control and performance verification of IVD tests are themselves often considered IVDs or accessories to IVDs.

Therefore, based on the intended use, it fits the definition of a device used in vitro for the examination of specimens derived from the human body to provide information for diagnostic purposes.

§ 862.1150 Calibrator.

(a)
Identification. A calibrator is a device intended for medical purposes for use in a test system to establish points of reference that are used in the determination of values in the measurement of substances in human specimens. (See also § 862.2 in this part.)(b)
Classification. Class II (special controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 862.9.

Dear Ms. Mallory:

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 aqainst 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.

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 requlation (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"
