S. aureus/CNS PNA FISH is a multicolor, qualitative nucleic acid hybridization assay intended for the identification of Staphylococcus aureus and/or selected other Staphylococcus species on smears made from positive blood cultures containing Grampositive cocci in clusters observed on Gram stain.
Subculturing of positive blood cultures is necessary for susceptibility testing and/or differentiation of mixed growth.
S. aureus/CNS PNA FISH is intended as an aid in the diagnosis of S. aureus bacteremia.
Not Found
The provided document is a 510(k) clearance letter from the FDA for a diagnostic kit, not a study report. It does not contain the detailed information required to fulfill the request. The document clears the S. aureus and/or other Staphylococcus species PNA FISH® Culture Identification Kit based on its substantial equivalence to predicate devices, but it does not describe the specific acceptance criteria or the study that proves the device meets those criteria in the level of detail requested.
Therefore, I cannot provide the requested table, sample sizes, expert qualifications, adjudication methods, multi-reader multi-case study details, standalone performance, ground truth types, or training set information.
The document only states the Indications for Use:
- Identification of Staphylococcus aureus and/or selected other Staphylococcus species on smears made from positive blood cultures containing Gram-positive cocci in clusters observed on Gram stain.
- Intended as an aid in the diagnosis of S. aureus bacteremia.
It also explicitly states: "Subculturing of positive blood cultures is necessary for susceptibility testing and/or differentiation of mixed growth." This implies the device is an identification aid, not a complete diagnostic solution for resistance or mixed infections.

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 misbranding 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.
{1}------------------------------------------------
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).
This letter will allow you to begin marketing your device as described in your Section 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 information about the application of labeling requirements to your device, or questions on the promotion and advertising of your device, please contact the Office of In Vitro Diagnostic Device Evaluation and Safety at (240) 276-0484. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97). You may obtain other general information on your responsibilities under the Act from the Division of Small Manufacturers, International and Consumer Assistance at its toll-free number (800) 638-2041 or (301) 443-6597 or at its Internet address http://www.fda.gov/cdrh/industry/support/index.html

§ 866.3700
Staphylococcus aureus serological reagents.(a)
Identification. Staphylococcus aureus serological reagents are devices that consist of antigens and antisera used in serological tests to identify enterotoxin (toxin affecting the intestine) producing staphylococci from cultured isolates. The identification aids in the diagnosis of disease caused by this bacterium belonging to the genusStaphylococcus and provides epidemiological information on these diseases. Certain strains ofStaphylococcus aureus produce an enterotoxin while growing in meat, dairy, or bakery products. After ingestion, this enterotoxin is absorbed in the gut and causes destruction of the intestinal lining (gastroenteritis).(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 the limitations in § 866.9.
