The device description and performance studies describe a lateral flow immunoassay that relies on chemical reactions and visual interpretation of lines on a test strip, with no mention of computational analysis or algorithms.
No
This device is a diagnostic test, providing qualitative detection of influenza antigens to aid in diagnosis, not a therapy or treatment itself.
Yes
Explanation: The "Intended Use / Indications for Use" section explicitly states that the device is "intended for use as an aid in the rapid differential diagnosis of acute influenza type A and type B viral infections."
No
The device description clearly outlines a physical test strip and reagents used to detect antigens, indicating it is a hardware-based diagnostic test, not software only.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states "rapid, qualitative detection of influenza type A and type B antigens directly from nasal swab, nasopharyngeal swab, nasal aspirate, and nasal wash specimens." This describes a test performed on a specimen taken from the human body to provide information about a person's health status (presence of influenza antigens).
- Device Description: The description details how the test works by reacting with a patient specimen (nasal swabs, etc.) to detect viral antigens. This is a characteristic of an in vitro diagnostic test.
- Specimen Type: The test uses specimens taken from the body (nasal, nasopharyngeal).
- Purpose: The purpose is to aid in the "rapid differential diagnosis of acute influenza type A and type B viral infections." This is a diagnostic purpose.
The definition of an In Vitro Diagnostic (IVD) is a medical device that is used to perform tests on specimens taken from the human body, such as blood, urine, or tissue, to provide information about a person's health status. This device clearly fits that definition.

Device Description
Nasal swabs, nasopharyngeal swabs, nasal wash and/or nasal aspirates serve as specimens for this test. The patient specimen is placed in a tube containing Extraction Reagent, during which time the virus particles in the specimen are disrupted, exposing internal viral antigens. After extraction, the Test Strip is placed in the Extraction Tube for 10 minutes. During this time, the extracted specimen will react with the reagents in the Test Strip.
If the extracted specimen contains influenza Type A and/or B antigens, a pink-to-red Test Line along with a blue procedural Control Line will appear on the test Strip. If influenza Type A and B viral antigens are not present, or present at very low levels, only a blue procedural Control Line will appear. If no blue procedural Control Line develops, the result is considered invalid.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
An analytical study was performed with cultured viruses to determine the analytical sensitivity or minimum detectable level of the QuickVue Influenza A+B for cultured strains of seasonal H1N1 (New Caledonia/20/1999) and 2009 H1N1 (California/04/2009).
The results of this study show that QuickVue Influenza A+B shows reactivity to the cultured strain of 2009 H1N1 Influenza A virus (Californial04/2009) with a minimum detectable level of 1.63 X 10^3 TCID50/ml. Although this test has been shown to detect the 2009 H1N1 virus cultured from a positive human respiratory specimen, the performance characteristics of this device with clinical specimens that are positive for the 2009 H1N1 influenza virus have not been established. The QuickVue Influenza A+B test can distinguish between influenza A and B viruses, but it can not differentiate influenza subtypes.
Key Metrics (Sensitivity, Specificity, PPV, NPV, etc.)
Minimum detectable level of 1.63 X 10^3 TCID50/ml for cultured strain of 2009 H1N1 Influenza A virus (Californial04/2009).

§ 866.3328 Influenza virus antigen detection test system.
(a)
Identification. An influenza virus antigen detection test system is a device intended for the qualitative detection of influenza viral antigens directly from clinical specimens in patients with signs and symptoms of respiratory infection. The test aids in the diagnosis of influenza infection and provides epidemiological information on influenza. Due to the propensity of the virus to mutate, new strains emerge over time which may potentially affect the performance of these devices. Because influenza is highly contagious and may lead to an acute respiratory tract infection causing severe illness and even death, the accuracy of these devices has serious public health implications.(b)
Classification. Class II (special controls). The special controls for this device are:(1) The device's sensitivity and specificity performance characteristics or positive percent agreement and negative percent agreement, for each specimen type claimed in the intended use of the device, must meet one of the following two minimum clinical performance criteria:
(i) For devices evaluated as compared to an FDA-cleared nucleic acid based-test or other currently appropriate and FDA accepted comparator method other than correctly performed viral culture method:
(A) The positive percent agreement estimate for the device when testing for influenza A and influenza B must be at the point estimate of at least 80 percent with a lower bound of the 95 percent confidence interval that is greater than or equal to 70 percent.
(B) The negative percent agreement estimate for the device when testing for influenza A and influenza B must be at the point estimate of at least 95 percent with a lower bound of the 95 percent confidence interval that is greater than or equal to 90 percent.
(ii) For devices evaluated as compared to correctly performed viral culture method as the comparator method:
(A) The sensitivity estimate for the device when testing for influenza A must be at the point estimate of at least 90 percent with a lower bound of the 95 percent confidence interval that is greater than or equal to 80 percent. The sensitivity estimate for the device when testing for influenza B must be at the point estimate of at least 80 percent with a lower bound of the 95 percent confidence interval that is greater than or equal to 70 percent.
(B) The specificity estimate for the device when testing for influenza A and influenza B must be at the point estimate of at least 95 percent with a lower bound of the 95 percent confidence interval that is greater than or equal to 90 percent.
(2) When performing testing to demonstrate the device meets the requirements in paragraph (b)(1) of this section, a currently appropriate and FDA accepted comparator method must be used to establish assay performance in clinical studies.
(3) Annual analytical reactivity testing of the device must be performed with contemporary influenza strains. This annual analytical reactivity testing must meet the following criteria:
(i) The appropriate strains to be tested will be identified by FDA in consultation with the Centers for Disease Control and Prevention (CDC) and sourced from CDC or an FDA-designated source. If the annual strains are not available from CDC, FDA will identify an alternative source for obtaining the requisite strains.
(ii) The testing must be conducted according to a standardized protocol considered and determined by FDA to be acceptable and appropriate.
(iii) By July 31 of each calendar year, the results of the last 3 years of annual analytical reactivity testing must be included as part of the device's labeling. If a device has not been on the market long enough for 3 years of annual analytical reactivity testing to have been conducted since the device received marketing authorization from FDA, then the results of every annual analytical reactivity testing since the device received marketing authorization from FDA must be included. The results must be presented as part of the device's labeling in a tabular format, which includes the detailed information for each virus tested as described in the certificate of authentication, either by:
(A) Placing the results directly in the device's § 809.10(b) of this chapter compliant labeling that physically accompanies the device in a separate section of the labeling where the analytical reactivity testing data can be found; or
(B) In the device's label or in other labeling that physically accompanies the device, prominently providing a hyperlink to the manufacturer's public Web site where the analytical reactivity testing data can be found. The manufacturer's home page, as well as the primary part of the manufacturer's Web site that discusses the device, must provide a prominently placed hyperlink to the Web page containing this information and must allow unrestricted viewing access.
(4) If one of the actions listed at section 564(b)(1)(A)-(D) of the Federal Food, Drug, and Cosmetic Act occurs with respect to an influenza viral strain, or if the Secretary of Health and Human Services (HHS) determines, under section 319(a) of the Public Health Service Act, that a disease or disorder presents a public health emergency, or that a public health emergency otherwise exists, with respect to an influenza viral strain:
(i) Within 30 days from the date that FDA notifies manufacturers that characterized viral samples are available for test evaluation, the manufacturer must have testing performed on the device with those viral samples in accordance with a standardized protocol considered and determined by FDA to be acceptable and appropriate. The procedure and location of testing may depend on the nature of the emerging virus.
(ii) Within 60 days from the date that FDA notifies manufacturers that characterized viral samples are available for test evaluation and continuing until 3 years from that date, the results of the influenza emergency analytical reactivity testing, including the detailed information for the virus tested as described in the certificate of authentication, must be included as part of the device's labeling in a tabular format, either by:
(A) Placing the results directly in the device's § 809.10(b) of this chapter compliant labeling that physically accompanies the device in a separate section of the labeling where analytical reactivity testing data can be found, but separate from the annual analytical reactivity testing results; or
(B) In a section of the device's label or in other labeling that physically accompanies the device, prominently providing a hyperlink to the manufacturer's public Web site where the analytical reactivity testing data can be found. The manufacturer's home page, as well as the primary part of the manufacturer's Web site that discusses the device, must provide a prominently placed hyperlink to the Web page containing this information and must allow unrestricted viewing access.

Intended Use:
The QuickVue Influenza A+B test allows for the rapid, qualitative detection of influenza type A and type B antigens directly from nasal swab, nasopharyngeal swab, nasal aspirate, and nasal wash specimens. The test is intended for use as an aid in the rapid differential diagnosis of acute influenza type A and type B viral infections. The test is not intended to detect influenza C antigens. Negative results should be confirmed by cell culture; they do not preclude influenza virus infection and should not be used as the sole basis for treatment or other management decisions. The test is intended for professional and laboratory use.
Physiologic Basis of the Test:
Inflyenza is a highly contagious, acute, viral infection of the respiratory tract. The causative agents of the disease are immunologically diverse, single-strand RNA viruses known as Influenza Viruses. There are three types of influenza viruses: A, B, and C. Type A viruses are the most prevalent and are associated with the most serious epidemics. Type B produces a disease that is generally milder than that caused by Type A. Type C has never been connected with a large epidemic of human disease. Both Type A and B viruses can circulate simultaneously, but usually one type is dominant during a given season.
Influenza antigens may be detected in clinical specimens by immunoassay. The QuickVue Influenza A+B test is a lateral-flow immunoassay using highly sensitive monoclonal antibodies that are specific for influenza antigens. The test is specific to influenza Types A and B antigen with not known cross-reactivity to normal flora or other known respiratory pathogens.
The QuickVue Influenza A+B test, has two Test Line indicators - one for type A and one for type B. The two Test Line indicators allow for the separate identification of type A and type B viral antigens from the same specimen. If either Test Line turns pink-to-red, the test is positive for influenza.

Summary of Performance Data:
- · An analytical study was performed with cultured viruses to determine the analytical sensitivity or minimum detectable level of the QuickVue Influenza A+B for cultured strains of seasonal H1N1 (New Caledonia/20/1999) and 2009 H1N1 (California/04/2009).
Conclusion:
The results of this study show that QuickVue Influenza A+B shows reactivity to the cultured strain of 2009 H1N1 Influenza A virus (Californial04/2009) with a minimum detectable level of 1.63 X 103 TCID50/ml. Although this test has been shown to detect the 2009 H1N1 virus cultured from a positive human respiratory specimen, the performance characteristics of this device with clinical specimens that are positive for the 2009 H1N1 influenza virus have not been established. The QuickVue Influenza A+B test can distinguish between influenza A and B viruses, but it can not differentiate influenza subtypes.
The QuickVue Influenza A+B is substantially equivalent with the current QuickVue Influenza A+B test.
