The Sensititre YeastOne Susceptibility System is an in vitro diagnostic product for clinical susceptibility testing of Candida spp. This 510(k) is for micafungin in the dilution range of 0.008-16 ug/mL for testing Candida spp. on The Sensitite YeastOne Susceptibility System. Micafungin has been shown to be active both clinically and in vitro against the following organisms according to the FDA drug label: Candida albicans Candida glabrata Candida guilliermondi Candida krusei Candida parapsilosis Candida tropicalis

I apologize, but the provided text from the FDA 510(k) clearance letter for "The Sensititre YeastOne Susceptibility System with Micafungin" does not contain the detailed information required to answer your specific questions about acceptance criteria and the study that proves the device meets those criteria.
This document is a formal clearance letter from the FDA stating that the device is substantially equivalent to legally marketed predicate devices. It covers:
- The trade/device name, regulation number, regulatory class, and product code.
- Confirmation of substantial equivalence.
- Information about general controls, special controls, the predetermined change control plan (PCCP), and other applicable regulations (Quality System, adverse event reporting, UDI Rule).
- Indications for Use of the device.
It specifically lacks the following information that would be necessary to address your request:
- Acceptance criteria table and reported device performance: The letter does not describe specific performance metrics (e.g., accuracy, sensitivity, specificity) or the thresholds for acceptance (e.g., "required to be > X%").
- Study details (sample size, data provenance, expert counts, adjudication, MRMC, standalone performance, ground truth type, training set details): The letter does not include any information about the design or results of the studies used to validate the device's performance. For an Antimicrobial Susceptibility Test (AST) system, performance is typically assessed by comparing its results (categorization into Susceptible, Intermediate, Resistant) against a reference method.
To obtain the information you're looking for, you would typically need to review the actual 510(k) submission summary publically available on the FDA website, or the relevant performance study reports and data that were provided by Thermo Fisher Scientific to the FDA for review. The clearance letter itself is a summary of the FDA's decision, not the underlying data or study methodology.
§ 866.1640 Antimicrobial susceptibility test powder.
(a)
Identification. An antimicrobial susceptibility test powder is a device that consists of an antimicrobial drug powder packaged in vials in specified amounts and intended for use in clinical laboratories for determining in vitro susceptibility of bacterial pathogens to these therapeutic agents. Test results are used to determine the antimicrobial agent of choice in the treatment of bacterial diseases.(b)
Classification. Class II (performance standards).
