SPOTFIRE® RSP Negative Control is intended for use (as applicable) as an external negative assayed quality control to monitor performance of in vitro laboratory nucleic acid testing procedures for the qualitative detection of Bordetella parapertussis. Bordetella pertussis. Chlamydia pneumoniae. Streptococcus dysgalactiae (Group C/G Strep), Streptococcus pyogenes (Group A Strep), Adenovirus SARS-CoV-2, Coronavirus (seasonal), Human Metapneumovirus, Human Rhinovirus, Influenza A Subtype H1-2009, Influenza A Subtype H3, Influenza B, Parainfluenza Virus and Respiratory Syncytial Virus using the BIOFIRE® SPOTFIRE Respiratory (R) Panel, BIOFIRE SPOTFIRE Respiratory (R) Panel Mini, BIOFIRE SPOTFIRE Respiratory/Sore Throat (R/ST) Panel, and BIOFIRE SPOTFIRE Respiratory/Sore Throat (R/ST) Panel Mini on the BIOFIRE System. SPOTFIRE RSP Negative Control is designed for and intended to be used solely with the BIOFIRE SPOTFIRE R Panel, BIOFIRE SPOTFIRE R Panel Mini, BIOFIRE SPOTFIRE R/ST Panel, and BIOFIRE SPOTFIRE R/ST Panel Mini assays. SPOTFIRE RSP Negative Control is comprised of a solution of buffer and preservatives that does not contain target analytes. This product is not intended to replace manufacturer internal controls provided with these devices.
Quality control materials should be used in accordance with local, state, federal regulations, and accreditation requirements.
SPOTFIRE RSP Pos & Neg Controls, P/N M425, is a quality control panel consisting of 12 readyto-use, liquid controls, 6 of SPOTFIRE RSP Positive Control (Positive Control), P/N M42638, and 6 of SPOTFIRE RSP Negative Control (Negative Control), P/N M42738, in a single kit box, and a separate kit of 6 additional SPOTFIRE RSP Negative Controls (Negative Control), P/N M42738. The separate kit of SPOTFIRE RSP Negative Control allows and encourages the end user to check for environmental contamination by testing additional negative controls. The Positive Control contains non-infectious surrogate control material; a solution of synthetic RNA transcripts in buffer, stabilizers and preservatives. The RNA in the Positive Control carries RNA segments of all the respiratory and sore throat pathogens detected by the BIOFIRE SPOTFIRE Respiratory (R) Panel, BIOFIRE SPOTFIRE Respiratory (R) Panel Mini, BIOFIRE SPOTFIRE Respiratory/Sore Throat (R/ST) Panel, and BIOFIRE SPOTFIRE Respiratory/Sore Throat (R/ST) Panel Mini assays. performed on the BIOFIRE System. SPOTFIRE RSP Pos & Neg Controls are specifically designed for and intended to be used solely with the BIOFIRE SPOTFIRE R Panel, BIOFIRE SPOTFIRE R Panel Mini, BIOFIRE SPOTFIRE R/ST Panel, and BIOFIRE SPOTFIRE R/ST Panel Mini assays on the BIOFIRE SPOTFIRE System. The Negative Control contains buffer and preservatives with no RNA. Each liquid control of SPOTFIRE RSP Pos & Neg Controls is processed separately according to the SPOTFIRE Panel assay manufacturer's Instructions for Use for patient samples (nasopharyngeal swabs or throat swabs placed in transport media) obtained from individuals with signs and symptoms of respiratory tract infection or pharyngitis. Engineering drawings, schematics, etc. are not applicable to the device (device is a reagent).
The provided text is a 510(k) premarket notification for a medical device called "SPOTFIRE® RSP Pos & Neg Controls." This document focuses on the regulatory aspects of changing an existing, cleared device (K233611) rather than presenting a detailed study proving performance against specific acceptance criteria for a new device.
Therefore, I cannot extract the information required to populate a table of acceptance criteria and reported device performance from this document, nor can I describe a study that proves the device meets specific acceptance criteria in the context of an AI/ML-driven medical device, as the device in question is an assayed quality control material for clinical microbiology assays, not an AI/ML diagnostic tool.
The document states:
- "Performance data presented in the predicate 510(k) submission (K233611) has all the required data to support the labeling change to the existing device to include the SPOTFIRE R/ST Panel Mini in the intended use for SPOTFIRE RSP Pos & Neg Controls, and the packaging change to combine Positive and Negative controls in a single kit box. No additional performance data are required as the SPOTFIRE RSP Pos & Neg Controls have not been changed, the assay consumables are identical for the SPOTFIRE R/ST Panel used to collect original performance data and the SPOTFIRE R Panel Mini. In addition, the targets reported in the SPOTFIRE R/ST Panel Mini are a subset of the SPOTFIRE R/ST Panel."
This explicitly states that no new performance study was conducted for this specific submission (K241289) because the changes were considered minor (labeling and packaging, and the new panel is a subset of an already cleared panel). The previous 510(k) (K233611) would contain the original performance data, but that information is not provided in this document.
As a result, I cannot provide details on:
- A table of acceptance criteria and the reported device performance: Not present, as no new performance study was conducted.
- Sample size used for the test set and data provenance: Not present.
- Number of experts used to establish ground truth and qualifications: Not applicable/present.
- Adjudication method for the test set: Not applicable/present.
- Multi Reader Multi Case (MRMC) comparative effectiveness study: Not applicable, as this is a quality control material, not an AI diagnostic tool involving human readers.
- Standalone (algorithm only) performance: Not applicable.
- Type of ground truth used (expert consensus, pathology, outcomes data, etc.): Not applicable/present in this document.
- Sample size for the training set: Not applicable (not an AI/ML device, and no new training/testing).
- How the ground truth for the training set was established: Not applicable.
The document's purpose is to demonstrate substantial equivalence to an existing predicate device based on minor changes, not to present novel performance data for a new device.

(iv) Where applicable, assessment of matrix effects and any significant differences between the quality control material and typical patient samples in terms of conditions known to cause analytical error or affect assay performance.
(v) Where applicable, identify or define traceability or relationship to a domestic or international standard reference material and/or method.
(vi) Where applicable, detailed documentation related to studies for surrogate controls.
(3) Premarket notification submissions must include an adequate mitigation (e.g., real-time stability program) to the risk of false results due to potential modifications to the assays specified in the device's 21 CFR 809.10 compliant labeling.

(A) Assayed control material analyte(s);
(B) Whether the material is intended for quantitative or qualitative assays;
(C) Stating if the material is a surrogate control; and
(D) The system(s), instrument(s), or test(s) for which the quality control material is intended.
