No
The summary describes a nucleic acid hybridization assay for identifying bacteria, which is a biochemical method, not an AI/ML technology. There are no mentions of AI, ML, image processing, or data-driven algorithms.
No
The device is a diagnostic assay for identifying bacteria (E. coli/K. pneumoniae and P. aeruginosa) from blood cultures. It aids in identification, which is a diagnostic function, not a therapeutic one.
Yes
The device is described as a "qualitative nucleic acid hybridization assay intended for identification of Escherichia coli /Klebsiella pneumoniae and Pseudomonas aeruginosa on smears from positive blood cultures." It also states it is "indicated for use in conjunction with positive blood subcultures as an aid in the identification of E. coli/K. pneumoniae, and/or P. aeruginosa," which directly contributes to a diagnosis.
No
The provided text describes a nucleic acid hybridization assay, which is a laboratory test involving chemical reagents and biological samples. This inherently involves physical components and processes, not solely software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- "In Vitro Diagnostic" definition: IVDs are medical devices used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information for diagnosis, monitoring, or screening.
- Intended Use: The provided text explicitly states the device is an "assay intended for identification of Escherichia coli /Klebsiella pneumoniae and Pseudomonas aeruginosa on smears from positive blood cultures containing Gram-negative rods."
- Specimen Type: It uses "smears from positive blood cultures," which are specimens taken from the human body.
- Purpose: The purpose is "identification" of specific bacteria, which is a key function of diagnostic tests.
- Aid in Identification: The intended use also states it's an "aid in the identification," further confirming its diagnostic role.
Therefore, based on the intended use and the type of specimen it analyzes, the EK/P. aeruginosa PNA FISH assay clearly fits the definition of an In Vitro Diagnostic device.
N/A
Intended Use / Indications for Use
EK/P. aeruginosa PNA FISH is a multicolor, qualitative nucleic acid hybridization assay intended for identification of Escherichia coli IKlebsiella pneumoniae and Pseudomonas aeruginosa on smears from positive blood cultures containing Gram-negative rods. The test does not distinguish between E. coli and K. pneumoniae. Further testing is needed to differentiate E. coli and K. pneumoniae. The EK/P. aeruginosa PNA FISH assay is indicated for use in conjunction with positive blood subcultures as an aid in the identification of E. colilK. pneumoniae, and/or P. aeruginosa.

§ 866.2660 Microorganism differentiation and identification device.
(a)
Identification. A microorganism differentiation and identification device is a device intended for medical purposes that consists of one or more components, such as differential culture media, biochemical reagents, and paper discs or paper strips impregnated with test reagents, that are usually contained in individual compartments and used to differentiate and identify selected microorganisms. The device aids in the diagnosis of disease.(b)
Classification. Class I (general controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to § 866.9.

Dear Ms. Bulger:
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 misburanding and adulteration.
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 aft the Act or any Federal statutes and regulations administered by other Federal agencies. Your 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).
