Regulatory Class: II
Product Code: JWY
Here's a breakdown of what can and cannot be answered based on the provided text:
1. A table of acceptance criteria and the reported device performance
- Cannot be fully provided as typical performance metrics (e.g., sensitivity, specificity, accuracy) are not included in this document.
- The acceptance criteria for substantial equivalence are generally that the device is as safe and effective as a legally marketed predicate device.
- The document states that the FDA "determined the device is substantially equivalent... to legally marketed predicate devices." This is the core finding, implying the performance met the FDA's criteria for equivalence based on the submitted data.
- The "reported device performance" is summarized as the ability of the Sensititre 18-24 hour MIC panel to test for Cefdinir susceptibility in specific non-fastidious gram-negative isolates (Citrobacter diversus, Escherichia coli, Klebsiella pneumoniae, and Proteus mirabilis) in a dilution range of 0.06 - 64 ug/ml.
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
- Not explicitly stated in the provided text. The letter mentions "In vitro data" was provided. Details about the sample size (number of isolates tested), country of origin, or study design (retrospective/prospective) are not present.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
- Not explicitly stated in the provided text. For susceptibility testing, ground truth is typically established by a reference method (e.g., agar dilution or broth microdilution following CLSI guidelines), not by human expert consensus in the way it might be for image interpretation.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
- Not applicable and not stated. Adjudication methods like 2+1 or 3+1 are typically used in studies involving human interpretation where consensus among experts is needed. For an in vitro diagnostic device measuring antimicrobial susceptibility, the ground truth is usually an objective measurement from a reference method.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
- Not applicable. This device is an in vitro diagnostic (IVD) for antimicrobial susceptibility testing, which is a laboratory assay. It does not involve "human readers" interpreting images or other complex data that would necessitate an MRMC study or AI assistance in the way described.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- Not applicable in the AI sense. The Sensititre system is a standalone automated/semi-automated system for determining Minimum Inhibitory Concentration (MIC). Its performance is evaluated independently of human interpretation of complex patterns, but a laboratory technologist would still perform the test and interpret the numerical MIC results against breakpoints. So, while it's an "algorithm only" in the sense it provides a direct result, it's not "AI" in the modern sense of machine learning for complex pattern recognition. The "standalone performance" would refer to its accuracy compared to a reference method, which is implied by the substantial equivalence determination.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
- For antimicrobial susceptibility testing, the ground truth is typically established by a reference method, such as the Clinical and Laboratory Standards Institute (CLSI) recommended broth microdilution or agar dilution methods. The device's results (MIC values) would have been compared to these reference method results for accuracy.
8. The sample size for the training set
- Not explicitly stated in the provided text. This is not typically disclosed in a 510(k) clearance letter. For an IVD like this, there isn't a "training set" in the machine learning sense. Instead, there are validation studies performed with a sufficient number of bacterial isolates to demonstrate the device's accuracy and reproducibility.
9. How the ground truth for the training set was established
- Not applicable for a "training set" in the AI sense. As mentioned above, ground truth for such IVDs is established by comparing results to a recognized reference method for antimicrobial susceptibility testing (e.g., CLSI guidelines).

The new TracCell™ 2000 Slide Mapping System is intended as a computeraided Slide Mapping System integrated to an automated optical microscope workstation (AccuMed International's AcCell™ Workstation). The TracCell™ 2000 Slide Mapping System is used to map adequately stained. well-preserved. cervical cytology preparations that have been prepared using a Papanicolaou or Pap-like stained protocol. In addition to the present intended use as cleared by FDA, the new TracCell™ 2000 Slide Mapping System can be used for the purposes of mapping Cytyc ThinPrep® specimens. The mapping of the slide into ìpresentedî and iexcludedî fields of view is performed by segmenting the light-absorbing objects from background material based upon standard image processing techniques for efficient presentation to a cytotechnologist or cytopathologist for diagnostic interpretation.
-
- All cellular material within the expanded cell deposition area, comprising the standard cellular deposition area, and a narrow bleed zone immediately surrounding it, will be presented for human screening, using the minimum number of fields-of-view.
-
- All adequately stained, well preserved cells located in the annular ring, the area lying between the expanded cellular deposition area, and the imprinted boundary area and the imprinted boundaries of the slide, will be included in additional fields-of-view presented for human screening.
The mapping of a Cytyc Thin Prep™ specimen is carried out in precisely the same manner as the predicate TracCell 2000 Slide Mapping System. The mapping of the slide in presented and excluded fields-of view, is performed by segmenting the light absorbing objects from background material based upon standard image processing techniques for efficient presentation to a cytotechnologist or cytopathologist for diagnostic interpretation. These techniques are identical to the predicate TracCell 2000™.

Acceptance Criteria and Study for TracCell™ 2000 Slide Mapping System
The provided 510(k) letter and "Indications For Use" document do not contain a table of explicit acceptance criteria or reported device performance data from a study conducted for this specific submission. The focus of the 510(k) is on demonstrating substantial equivalence to a predicate device, not on presenting novel performance data against pre-defined acceptance criteria.
The "Indications For Use" outlines how the device performs its mapping function, which can be interpreted as the functional requirements it aims to fulfill.
1. Table of Acceptance Criteria and Reported Device Performance
Acceptance Criteria (Inferred from Indications For Use) | Reported Device Performance (Not stated in document) |
---|---|
1. Present all cellular material within the expanded cell deposition area (standard area + narrow bleed zone) for human screening using the minimum number of fields-of-view. | Not reported in this document. The document states this is the intended function of the device. |
2. Include all adequately stained, well-preserved cells in the annular ring (between expanded cellular deposition area and imprinted boundary) in additional fields-of-view for human screening. | Not reported in this document. The document states this is the intended function of the device. |
3. Map Cytyc ThinPrep® specimens in the same manner as the predicate TracCell 2000™. | Not reported in this document. The document states this is the intended function of the device and that the techniques are identical to the predicate. |
4. Segment light-absorbing objects from background material using standard image processing techniques for efficient presentation. | Not reported in this document. |
2. Sample size used for the test set and the data provenance
- Sample Size (Test Set): Not specified in the provided documents.
- Data Provenance: Not specified in the provided documents. The document refers to the device mapping "adequately stained, well-preserved, cervical cytology preparations." It does not mention country of origin or whether data was retrospective or prospective.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
- Number of Experts: Not specified in the provided documents.
- Qualifications of Experts: Not specified in the provided documents. The system aims to present fields-of-view to a "cytotechnologist or cytopathologist for diagnostic interpretation," implying these are the end-users whose diagnostic interpretations would ultimately be the clinical ground truth.
4. Adjudication method for the test set
- Adjudication Method: Not specified in the provided documents.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
- MRMC Study: Not specified or indicated in the provided documents. The 510(k) process often relies on substantial equivalence to a predicate device, and the provided text does not describe a comparative effectiveness study with human readers. The device serves to "map" and provide "efficient presentation" for human screening, rather than replacing or directly augmenting diagnostic performance in a quantifiable way described here.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- Standalone Performance: Not explicitly stated as being evaluated. The device is described as a "computer-aided Slide Mapping System" for "efficient presentation to a cytotechnologist or cytopathologist for diagnostic interpretation." This strongly implies a human-in-the-loop system, where the algorithm 'pre-processes' the slide for human review, rather than making a standalone diagnostic call.
7. The type of ground truth used
- Type of Ground Truth: The document implies that the human interpretation by a "cytotechnologist or cytopathologist" is the ultimate diagnostic ground truth for cervical cytology. The device's role is to ensure all relevant areas are presented for this human interpretation. The ground truth for the mapping function itself would likely be related to whether all cellular material (as defined) is indeed presented.
8. The sample size for the training set
- Sample Size (Training Set): Not specified in the provided documents.
9. How the ground truth for the training set was established
- Ground Truth (Training Set): Not specified in the provided documents. The device uses "standard image processing techniques" for segmentation, which would typically rely on established principles for identifying cellular material.
