Intended Use
The Cepheid Xpert® SA Nasal Complete Control Panel is intended for use as an external assayed positive and negative quality control to monitor the performance of in vitro laboratory nucleic acid testing procedures for the qualitative detection of Methicilin-Resistant Staphylococcus aureus (MRSA) and Staphylococcus aureus (SA) performed with the Cepheid Xpert® SA Nasal Complete Assay on the GeneXpert® Dx System. The controls comprise cultured and inactivated Methicillin-Resistant Staphylococcus aureus as the positive control 1: Staphylococcus aureus as the positive control 2; Staphylococcus epidermidis as the negative control. The Cepheid Xpert® SA Nasal Complete Control Panel is not intended to replace manufacturer controls provided with the Cepheid Xpert® SA Nasal Complete Assay.
Device Description
The Cepheid Xpert® SA Nasal Complete Control Panel is used to monitor the DNA extraction, amplification and detection processes of the Cepheid Xpert® SA Nasal Complete Assay. The Cepheid Xpert® SA Nasal Complete Control Panel contains cultured microorqanisms inactivated by heat treatments. Each Cepheid Xpert® SA Nasal Complete Control Panel consists of 6 individually packaged Methicillin-Resistant Staphylococcus aureus (MRSA) positive control swabs (positive control 1): 6 individually wrapped Staphylococcus aureus (MSSA) positive controls swabs (positive control 2); and 6 individually wrapped negative control swabs. Each positive control 1 swab contains MRSA at a target level that is designed to provide reproducible performance above the limit of detection for each of the genes targeted by the Cepheid Xpert® SA Nasal Complete Assay: Staphylococcal protein A gene spa (SPA), methicillin resistance gene mecA (mec), and the Staphylococcal cassette chromosome (SCC). Each positive control 2 swab contains MSSA at a target level designed to provide reproducible performance above the limit of detection of the spa gene target of the Cepheid Xpert® SA Nasal Complete Assay. Each negative control swab contains Staphylococcus epidermidis (MSSE) which is methicillin susceptible and not detected by the Cepheid Xpert® SA Nasal Complete Assay. Each swab is individually wrapped with a desiccant in a heat-sealed foil pouch.
More Information

No
The document describes a quality control panel for a nucleic acid test, focusing on the biological components and their intended use for monitoring assay performance. There is no mention of AI or ML in the device description, intended use, or performance studies.

No
This device is a quality control panel for an in vitro diagnostic test, not a device used for therapy or treatment.

No

Explanation: The device is described as a quality control panel intended to monitor the performance of nucleic acid testing procedures, not to diagnose a condition in a patient. It is used to ensure the accuracy of other diagnostic tests.

No

The device description clearly states it contains cultured microorganisms and swabs, which are physical components, not software.

Yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The "Intended Use / Indications for Use" section explicitly states that the device is "intended for use as an external assayed positive and negative quality control to monitor the performance of in vitro laboratory nucleic acid testing procedures". This directly aligns with the definition of an in vitro diagnostic device, which is used to examine specimens taken from the human body to provide information for diagnosis, monitoring, or screening.
  • Device Description: The description details that the device is used to monitor the "DNA extraction, amplification and detection processes" of an in vitro assay. This further confirms its role in the in vitro diagnostic workflow.
  • Care Setting: The intended user is an "in vitro laboratory", which is where in vitro diagnostic testing is performed.

The device is a quality control for an IVD assay, and quality controls for IVD assays are themselves considered IVDs.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

A precision and reproducibility study was conducted to determine device performance. Three different testing locations were used. Six different operators (2 at each facility) and 3 different lots of the Cepheid Xpert® SA Nasal Complete Control Panel were tested over five days. Each operator performed a minimum of 3 tests (1 per lot) on 5 different days. All testing was performed on a GeneXpert® Dx System using the Cepheid Xpert® SA Nasal Complete Assay.

Key results:
