Intended Use
The Micro H2 is a hand held hydrogen monitor used in the screening and diagnosis of lactose malabsorption, a condition that produces increased hydrogen levels in the blood when unabsorbed lactose reacts with bacteria in the intestines. This increased level of hydrogen is expired and can be measured after ingestion of lactose following a period of fasting. Federal (U.S.A.) Law restricts this device to sale by or on the order of a physician. Target Population: Adult, Child and Infant.
Device Description
The Micro H2 Breath Monitoring device is a battery operated hand held hydrogen breath monitor. Clinicians using this device have a patient expel their breath into an inlet port through a disposable mouthpiece adapter. The hydrogen concentration is then displayed in parts per million (ppm). The software utility, product name Hydra, will be supplied to purchasers of the breath hydrogen monitoring device. At the clinician's discretion, they can install Hydra on a Windows based PC. Thereafter, the handheld Micro H2 device can be connected to the PC via a serial communications cable to acquire and log successive breath hydrogen measurements during a diagnostic procedure.
More Information

Not Found

No
The summary describes a device that measures hydrogen concentration and logs data, but there is no mention of AI or ML being used for analysis, interpretation, or any other function.

No.
The device is used for the screening and diagnosis of lactose malabsorption by measuring hydrogen levels, which is a diagnostic function, not a therapeutic one.

Yes

The 'Intended Use / Indications for Use' section explicitly states, "The Micro H2 is a hand held hydrogen monitor used in the screening and diagnosis of lactose malabsorption..." This indicates its purpose is to identify or determine a medical condition.

No

The device description explicitly states it is a "battery operated hand held hydrogen breath monitor" and mentions a "handheld Micro H2 device" that connects to a PC, indicating it includes hardware.

Based on the provided information, yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use explicitly states that the device is used in the "screening and diagnosis of lactose malabsorption." This is a diagnostic purpose.
  • Sample Type: The device measures hydrogen levels in "expired breath," which is a biological sample taken from the patient.
  • Analysis: The device analyzes the hydrogen concentration in the breath sample to provide a measurement (in ppm) that is used in the diagnostic process.
  • Regulatory Restriction: The statement "Federal (U.S.A.) Law restricts this device to sale by or on the order of a physician" is a common indicator of a medical device, and often applies to IVDs.

While the device description focuses on the hardware and software, the core function and intended use clearly align with the definition of an In Vitro Diagnostic device, which is used to examine specimens derived from the human body to provide information for the diagnosis, prevention, or treatment of a disease or condition.

Trade/Device Name: Micro H2 Breath Monitoring Device with Hydra Software Utility Regulation Number: 21 CFR 862.1820 Regulation Name: Xylose test system Regulatory Class: Class I Product Code: NRH Dated: May 5, 2004 Received: May 6, 2004

Dear Mr. Staszak:

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 adultcration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), 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); and good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820).
