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, nasal wash and nasal aspirate 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. The test is intended for professional and laboratory use.
Device Description
The QuickVue Influenza A + B test, the successor product to the QuickVue Influenza 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 pinkto-red, the test is positive for influenza. Nasal 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.
More Information

No
The device description details a lateral flow immunoassay that relies on chemical reactions and visual interpretation of color changes, with no mention of computational analysis, algorithms, or learning processes.

No.
The device is a diagnostic test that detects antigens to aid in the diagnosis of influenza, rather than providing therapy or treatment.

Yes
The device is described as "an aid in the rapid differential diagnosis of acute influenza type A and type B viral infections," which directly indicates its use for diagnostic purposes.

No

The device description clearly outlines a physical test strip and reagents, 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, nasal wash and nasal aspirate specimens." This involves testing a specimen taken from the human body in vitro (outside the body) to provide information about a person's health status (presence of influenza).
  • Device Description: The description details how the test works by reacting the patient specimen with reagents on a test strip to detect viral antigens. This is a classic description of an in vitro diagnostic assay.
  • Specimen Type: The test uses nasal swab, nasal wash, and nasal aspirate specimens, which are biological samples taken from a patient.
  • Performance Studies: The document describes clinical and analytical studies conducted to evaluate the performance of the test using clinical specimens. This is a requirement for IVD devices to demonstrate their accuracy and reliability.
  • Predicate Devices: The listed predicate devices (Quidel QuickVue® Influenza test, BD Directigen™ Flu A+B test, BioStar® AB Flu OIA® test) are all known IVD devices for influenza detection. This further supports the classification of this device as an IVD.

The definition of an IVD generally includes devices intended for use in the examination of specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device clearly fits that definition.

§ 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.

BioStar® AB Flu OIA® test (K023556)
Device Classification:21 CFR 866.3330
The device, the QuickVue Influenza A + B test,
is similar to other FDA-cleared devices used
for the qualitative detection of influenza type A
and B directly from clinical specimens. These
tests are used to aid in the diagnosis of
disease cause by influenza viruses A and B
and provide epidemiological information on
these diseases (21CFR 866.3330).
The Food and Drug Administration has
proposed that serological test systems for the
detection of influenza virus be classified as
Class I.
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, nasal wash and nasal aspirate
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. The test is intended for professional
and laboratory use.

  • Physiologic Basis of the Test: Influenza 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 no know cross-reactivity to normal flora or other known respiratory pathogens.

  • Device Description: The QuickVue Influenza A + B test, the successor product to the QuickVue Influenza 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 pinkto-red, the test is positive for influenza.
    Nasal 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.
