More Information

No
The 510(k) summary describes a colorimetric assay kit for chemical analysis, with no mention of AI, ML, image processing, or data analysis techniques typically associated with AI/ML.

No
The device is an assay kit for diagnostic purposes (determining UBAS levels), not for treating a condition.

Yes
The device is described as an "Assay Kit for Urinary Total Bile Acid Sulfate" intended for the "colorimetric determination of urinary total bile acid sulfate (UBAS) in children and adults." This determination of a substance in the body (UBAS) for diagnostic purposes (though not explicitly stated as such, determination of biomarkers is a key step in diagnosis) classifies it as a diagnostic device.

No

The device description clearly states "Assay Kits," which implies physical components (reagents, containers, etc.) are involved, not just software.

Yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is the "colorimetric determination of urinary total bile acid sulfate (UBAS) in children and adults." This clearly indicates that the device is used to perform a test on a biological sample (urine) in vitro (outside the body) to obtain diagnostic information.
  • Device Description: The device is described as "Assay Kits for Urinary Total Bile Acid Sulfate." Assay kits are a common type of IVD used for performing specific tests on biological samples.
  • Anatomical Site: The test is performed on a sample from the "Urinary" system. This is a biological sample.

The key characteristic of an IVD is that it is used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device fits that description perfectly.

Dear Mr. Holland:

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 The general controls provisions of the Act of the Act. include requirements for annual registration, listing of devices, qood 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 requlations affecting your device can be found in the Code of Federal Requlations, Title 21, Parts 800 to 895. ಗಿ 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 In addition, FDA may publish further announcements action. 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 requlations.
