Not Found

No
The summary describes a linearity set for a test kit, which is a chemical reagent system, and there is no mention of AI or ML.

No
The device is used for estimating the linearity limits of a reagent/instrument system for an analyte, which is a laboratory quality control function, not a therapeutic intervention on a patient.

No
The device is used to estimate the linearity limits of a reagent/instrument system for an analyte (NEFA), which is a quality control function for a test kit, not a direct diagnostic activity on a patient sample.

No

The device description is not found, and the intended use describes a "linearity set" and "test kit" which strongly suggests physical components, not just software.

Based on the provided information, the Wako NEFA 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 a "Wako NEFAC test kit" for "estimation of the linearity limits of the reagent/instrument system for the NEFA analyte." This describes a product used in vitro (outside the body) to evaluate the performance of a diagnostic test system.
  • Function: The function of determining linearity limits is a crucial part of validating and ensuring the accuracy of a diagnostic test. This is a typical function of a product used in a clinical laboratory setting to support diagnostic testing.

While the "Device Description" is missing, the intended use strongly points towards it being a product used in the process of performing in vitro diagnostic tests.

Therefore, based on the provided text, it fits the definition of an IVD device.

§ 862.1660 Quality control material (assayed and unassayed).

(a)
Identification. A quality control material (assayed and unassayed) for clinical chemistry is a device intended for medical purposes for use in a test system to estimate test precision and to detect systematic analytical deviations that may arise from reagent or analytical instrument variation. A quality control material (assayed and unassayed) may be used for proficiency testing in interlaboratory surveys. This generic type of device includes controls (assayed and unassayed) for blood gases, electrolytes, enzymes, multianalytes (all kinds), single (specified) analytes, or urinalysis controls.(b)
Classification. Class I (general controls). Except when intended for use in donor screening tests, quality control materials (assayed and unassayed) are 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 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 Requlations, Title 21, Parts 800 to 895. ਰ 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 Reqister. 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 regulation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at (301) 594-4588.
