The summary describes a qualitative nucleic acid multiplex test and its associated data analysis software. There is no mention of AI or ML in the device description, intended use, or performance studies. The analysis is based on detecting specific viral nucleic acids, not on learning patterns or making predictions from data.
No.
The device is a diagnostic tool designed for the detection and identification of respiratory virus nucleic acids, aiding in diagnosis rather than providing direct therapy or treatment.
Yes
The "Intended Use / Indications for Use" section states that the device "aids in the diagnosis of respiratory viral infection if used in conjunction with other clinical and laboratory findings."
No
The device description explicitly lists hardware components such as primer mixes, bead mix, and buffer, in addition to the software. This indicates it is a system that includes both hardware and software, not a software-only device.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states that the device is a "qualitative nucleic acid multiplex test intended for the simultaneous detection and identification of multiple respiratory virus nucleic acids in nasopharyngeal swabs from individuals suspected of respiratory tract infections." This describes a test performed in vitro (outside the body) on a biological sample (nasopharyngeal swabs) to provide information for diagnosis.
- Sample Type: The device uses "nasopharyngeal swabs," which are biological specimens collected from a patient.
- Purpose: The purpose is to "aid in the diagnosis of respiratory viral infection if used in conjunction with other clinical and laboratory findings." This directly aligns with the definition of an IVD, which is used to examine specimens from the human body to provide information for diagnosis, monitoring, or treatment.
- Device Description: The components listed are typical of a molecular diagnostic test performed in a laboratory setting.
The information provided clearly indicates that the xTAG Respiratory Viral Panel is a test performed on biological samples in vitro to aid in the diagnosis of respiratory viral infections, which is the core definition of an In Vitro Diagnostic device.

Intended Use / Indications for Use
The xTAG Respiratory Viral Panel (RVP) is a qualitative nucleic acid multiplex test intended for the simultaneous detection and identification of multiple respiratory virus nucleic acids in nasopharyngeal swabs from individuals suspected of respiratory tract infections. The following virus types and subtypes are identified using RVP: Influenza A. Influenza A subtype H1, Influenza A subtype H3, Influchza B, Respiratory Syncytial Virus subtype A, Respiratory Syncytial Virus subtype B, Parainfluenza 1, Parainfluenza 2, and Parainfluenza 3 virus. Human Metapneumovirus, Rhinovirus, and Adenovirus. The detection and identification of specific viral nucleic acids from individuals exhibiting signs and symptoms of respiratory infection aids in the diagnosis of respiratory viral infection if used in conjunction with other clinical and laboratory findings. It is recommended that specimens found to be negative for Influenza B, Respiratory Synctial Virus subtype A and B, Parainfluenza 2, Parainfluenza 3 and Adenovirus, after examination using RVP be confirmed by cell culture. Negative results do not preclude respiratory virus infection and should not be used as the sole basis for diagnosis, treatment or other management decisions. Positive results do not rule out bacterial infection, or co-infection with other viruses. The agent detected may not be the definite cause of disease. The use of additional laboratory testing (e.g. bacterial culture, immunofluorescence, radiography) and clinical presentation must be taken into consideration in order to obtain the final diagnosis of respiratory viral infection.
Due to seasonal prevalence, performance characteristics for Influenza A/H1 were established primarily with retrospective specimens.
The RVP assay cannot adequately detect Adenovirus species C, or serotypes 7a and 41. The RVP primers for detection of thinovirus cross-react with enterovirus. A rhinovirus reactive result should be confirmed by an alternate method (e.g. cell culture).
Performance characteristics for Influenza A Virus were established when Influenza A/H3 and A/H1 were the predominant Influenza A viruses in circulation. When other Influenza A viruses are emerging, performance characteristics may vary. If infections with a novel Influenza A virus is suspected based on current clinical and epidemiological screening criteria recommended by public health authorities, specimens should be collected with appropriate infection control precautions for novel virulent Influenza viruses and sent to a state or local health department for testing. Viral culture should not be attempted in these cases unless a BSL 3+ facility is available to receive and culture specimens.

A study carried out during the 2009 Influenza A HINI (swine flu) outbreak in New York (Ginocchio & George, 2009), a total of 1,382 patient nasopharyngeal swab samples were initially tested with a variety of method including rapid antigen tests (n=1095), direct immunofluorescence (n=1164), and rapid virus culture (n=1140). Samples that tested positive for Influenza A with any of these methods, or derived from patients with a high potential to be infected with the 2009 Influenza A HINI strain, were further tested with xTAG RVP (n=375). A total of 201 of these samples were identified as Flu A positive by the RVP assay, two samples contained Influenza B, and other respiratory viruses in 58 samples (adenovirus, metapheumovirus. Parainfluenza 1. 2. 3. RSV, and rhinovirus). Sixty of the 201 Flu A positive samples were identified by xTAG RVP as seasonal strains (2 as H1 and 58 as H3). The remaining 14 Flu A positive samples were negative for both H1 and H3 by xTAG RVP (unsubtypeable). Frozen residual portions of 101 of the 141 unsubtypeable samples were forwarded to the Laboratory of Viral Diseases (Albany, NY) for further testing with the CDC rRT-PCR assay for 2009 Influenza A HINI (swine flu). A total of 99 of the 101 specimens tested with the CDC assay were identified as positive for 2009 Influenza A/H/N1 (CT37) on one or more of the influenza targets and could not be classified as positive for the 2009 Influenza A/H/N/ strain. These two samples also produced weak positive signals in the RVP assay.
A study by Ginocchio et al. (2009) evaluated the performance of a variety of diagnostic assays, including the xTAG RVP, for the 2009 Influenza A/H1N1 surveillance. In this study, a total of 2,715 patient nasopharyngeal swab samples were tested by xTAG RVP and 1265 of these were positive for influenza A. Of the 1265, 1108 were "flu A unsubtypeable", 151 were seasonal H3N2 and 6 were seasonal H1N1. Of the 1108 flu A unsubtypeable with the xTAG RVP, all were confirmed to be Influenza A/H1N1 with the CDC rRT-PCR assay.
Summary of Performance Studies
The xTAG RVP can detect the matrix gene of 2009 Influenza A/H1N1 but can not identify the hemagglutinin gene of the 2009 Influenza A/H1N1 in clinical specimens. The studies summarized below demonstrate that xTAG RVP is an effective aid in the detection of 2009 influenza A/HIN1 strains (Ginocchio & George, 2009; Ginocchio et al. 2009):
