Intended Use
The Cepheid Xpert® CT/NG 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 Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) performed with the Cepheid Xpert® CT/NG assay on the GeneXpert® Instrument System. The controls consist of cultured and inactivated Chlamydia trachomatis and Neisseria gonorrhoeae as the positive control and human cells as the negative control. The Cepheid Xpert® CT/NG Control Panel is not intended to replace manufacturer controls provided with the device.
Device Description
The Cepheid Xpert® CT/NG Control Panel is used to monitor the extraction, amplification and detection of the Cepheid Xpert® CT/NG Assay. The Cepheid Xpert® CT/NG Control Panel contains authentic pathogens inactivated by radiological or temperature treatments. Each Cepheid Xpert® CT/NG Control Panel consists of 6 individually packaged positive control swabs and 6 individually wrapped negative control swabs. Each positive control swab contains Chlamydia trachomatis and Neisseria gonorrhoeae as well as preservatives and stabilizers. Each negative control swab contains human cells as well as preservatives and stabilizers. Each swab is individually wrapped with a desiccant in a heat-sealed foil pouch.
More Information

Not Found

No
The device is a quality control panel for a nucleic acid test and does not involve data processing or analysis that would typically utilize AI/ML. The description focuses on the biological components and testing methodology.

No
Explanation: This device is a quality control panel used to monitor the performance of in vitro diagnostic tests, not to treat or diagnose patients directly.

No
This device is a control panel used to monitor the performance of an in vitro diagnostic assay, not a diagnostic device itself. It does not diagnose disease in patients but rather verifies the proper functioning of the diagnostic test.

No

The device is a physical control panel consisting of swabs containing biological material, not software.

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

Here's why:

  • Intended Use: The intended use explicitly states it is for "in vitro laboratory nucleic acid testing procedures." This is a key characteristic of IVDs, which are used to examine specimens from the human body to provide information for diagnostic purposes.
  • Device Description: The description details the components and how it is used to "monitor the extraction, amplification and detection" of an assay. This monitoring function is performed in vitro (outside the body) on laboratory samples.
  • Intended User / Care Setting: It is intended for use in an "in vitro laboratory," further reinforcing its IVD nature.
  • Function: The device acts as a quality control for a diagnostic assay (the Cepheid Xpert® CT/NG assay). Quality controls are essential components of IVD testing to ensure the accuracy and reliability of the results.

While it's a control panel and not the primary diagnostic assay itself, it is an integral part of the in vitro diagnostic process for detecting Chlamydia trachomatis and Neisseria gonorrhoeae.

The Cepheid Xpert CT/NG Control Panel was evaluated at three testing sites with two operators at each site (total of six operators). Three lots of the control material were tested with the Cepheid Xpert CT/NG assay on the Cepheid Xpert Instrument, over five days. Each positive control was tested in three replicates on each day. There were seven ERROR results (assay aborted due to instrument or reagent problem) and one INVALID result (failure of the internal control/s). Those samples were retested using a new control swab according to the Instructions for Use. All testing utilized the Xpert Vaginal/Endocervical Swab Specimen Collection kit.

Dear Tina Sobania:

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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.

Summary of Performance Data:

The Cepheid Xpert CT/NG Control Panel was evaluated at three testing sites with two operators at each site (total of six operators). Three lots of the control material were tested with the Cepheid Xpert CT/NG assay on the Cepheid Xpert Instrument, over five days. Each positive control was tested in three replicates on each day. There were seven ERROR results (assay aborted due to instrument or reagent problem) and one INVALID result (failure of the internal control/s). Those samples were retested using a new control swab according to the Instructions for Use. All testing utilized the Xpert Vaginal/Endocervical Swab Specimen Collection kit.
