Intended Use
The Roche Diagnostics, Boehringer Mannheim Inorganic Phosphorus reagent is intended for use for the quantitative in vitro determination of phosphorus in human serum, plasma and urine with automated clinical chemistry analyzers. According to the Code of Federal Regulations, Title 21 (Food and Drugs), Part 862.1580, a Phosphorus (inorganic) test system is a device intended to measure inorganic phosphorus in serum, plasma, and urine. Measurements of phosphorus (inorganic) are used in the diagnosis and treatment of various disorders, including parathyroid gland and kidney diseases, and vitamin D imbalance.
Device Description
Endpoint method with sample blanking. Inorganic phosphate forms an ammonium phosphomolybdate complex with ammonium molybdate in the presence of sulfuric acid. The complex is determined photometrically in the ultraviolet region (340 nm).

No
The summary describes a chemical reagent and its photometric measurement method, with no mention of AI or ML technologies.

No

Explanation: This device is an in vitro diagnostic (IVD) reagent used to measure phosphorus levels in biological samples. While the measurements are used in the "diagnosis and treatment of various disorders," the device itself does not directly treat or prevent a disease; it provides information for diagnostic purposes.

Yes

Explanation: The "Intended Use / Indications for Use" section explicitly states that the device is "intended for use for the quantitative in vitro determination of phosphorus in human serum, plasma and urine" and that "Measurements of phosphorus (inorganic) are used in the diagnosis and treatment of various disorders, including parathyroid gland and kidney diseases, and vitamin D imbalance." This clearly indicates its role in diagnosis.

No

The device description clearly indicates it is a reagent used with automated clinical chemistry analyzers, which are hardware devices. The reagent itself is a chemical substance, not software.

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

Here's why:

  • Intended Use: The "Intended Use / Indications for Use" section explicitly states that the reagent is "intended for use for the quantitative in vitro determination of phosphorus in human serum, plasma and urine". The term "in vitro" is a key indicator of an IVD.
  • Regulatory Definition: The text references the Code of Federal Regulations, Title 21 (Food and Drugs), Part 862.1580, which defines a "Phosphorus (inorganic) test system" as a device intended to measure inorganic phosphorus in serum, plasma, and urine. This aligns perfectly with the device's intended use.
  • Purpose: The regulatory definition also states that these measurements are "used in the diagnosis and treatment of various disorders". This diagnostic purpose is a core characteristic of IVDs.
  • Device Description: The description details a chemical reaction and photometric measurement, which are typical methods used in laboratory testing of biological samples.

Therefore, based on the provided information, the Roche Diagnostics, Boehringer Mannheim Inorganic Phosphorus reagent clearly fits the definition and purpose of an In Vitro Diagnostic device.

Dear Ms. Tribbett:

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 (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.
