Binax™ Now® Legionella Urinary Antigen Test
Not Found
No
The device description details a standard immunochromatographic assay with visual interpretation, and there is no mention of AI or ML in the text.
No.
The device is an in vitro diagnostic test intended to aid in the presumptive diagnosis of Legionnaires' disease, rather than treating or preventing the disease.
Yes
The device is intended to "aid in the presumptive diagnosis of Legionnaires' disease," which directly relates to diagnosing a medical condition.
No
The device description clearly outlines a physical test device (cassette format) that utilizes immunochromatographic principles and involves the addition of a urine sample to a physical pad and membrane. This is a hardware-based in vitro diagnostic device, not a software-only device.
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 an "in vitro immunochromatographic rapid assay for the presumptive qualitative detection of Legionella pneumophila serogroup 1 antigens in human urine." The term "in vitro" means "in glass" or "in the lab," referring to tests performed outside of the living body.
- Device Description: The description details how the test works by analyzing a biological sample (urine) using chemical and immunological reactions on a test device. This is characteristic of an in vitro diagnostic test.
- Anatomical Site: The test is performed on "human urine," which is a biological specimen collected from the body for analysis.
Therefore, based on the provided information, the SAS™ Legionella Test clearly fits the definition of an In Vitro Diagnostic device.

Intended Use / Indications for Use
The SAS™ Legionella Test is a visually read, in vitro immunochromatographic rapid assay for the presumptive qualitative detection of Legionella pneumophila serogroup 1 antigens in human urine. This test is intended to aid in the presumptive diagnosis of Legionnaires' disease in conjunction with culture and other methods for patients with signs and symptoms of pneumonia. This test is for prescription use only.

Device Description
The SAS™ Legionella test utilizes a combination of polyclonal antibodies against the antigens of Legionella pneumophila. The SAS™ Legionella test begins with the addition of urine to the test device. The specimen is absorbed by the sample pad and then moves through the conjugate pad which contains dried gold conjugated antibodies which are specific for Legionella pneumophila antigens; if the Legionella antigens are present in the urine sample, a "half-sandwich" immunocomplex is formed. This immuno-complex then migrates via capillary action along a nitrocellulose membrane containing immobilized antibodies to Legionella pneumophila antigens. The immobilized antibodies bind the "half-sandwich" immuno-complex to form a "whole sandwich" immuno-complex. Thus, when the "whole sandwich" is formed, a visible, pink colored line develops in the specimen zone on the test device. In the absence of a Legionella antigen, a "sandwich" immuno-complex is not formed and a negative result is indicated. To serve as a procedural control, a pink colored control line will always appear in the control zone regardless of the presence or absence of Legionella antigen. The test is available in cassette format.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The SAS™ Legionella Test performed substantially equivalent to the predicate device, Binax™ Now® Legionella Urinary Antigen Test and to culture. This was verified by comparison of frozen and fresh urine specimens. Cross reactivity and interference studies were performed on viral and bacterial strains commonly found in human urine. None of the organisms interfered or cross-reacted with the performance of the SAS™ Legionella Test.

§ 866.3300
Haemophilus spp. serological reagents.(a)
Identification. Haemophilus spp. serological reagents are devices that consist of antigens and antisera, including antisera conjugated with a fluorescent dye, that are used in serological tests to identifyHaemophilus spp. directly from clinical specimens or tissue culture isolates derived from clinical specimens. The identification aids in the diagnosis of diseases caused by bacteria belonging to the genusHaemophilus and provides epidemiological information on diseases cause by these microorganisms. Diseases most often caused byHaemophilus spp. include pneumonia, pharyngitis, sinusitis, vaginitis, chancroid venereal disease, and a contagious form of conjunctivitis (inflammation of eyelid membranes).(b)
Classification. Class II (special controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to § 866.9.

Quality Controls: The SAS™ Legionella Test provides two (2) internal procedural controls. It is recommended that external quality controls should be performed on each new test kit box opened. Positive and negative external controls are supplied separately.
Device Comparison: The SAS™ Legionella Test and Binax™ Now® Legionella Urinary Antigen Test are rapid immunoassays tests utilizing immunochromatographic technology for the visualization of Legionella pneumophila antigen. Each utilizes an antibody conjugated to colored particles and an antibody printed onto a membrane.
Performance Summary: The SAS™ Legionella Test performed substantially equivalent to the predicate device, Binax™ Now® Legionella Urinary Antigen Test and to culture. This was verified by comparison of frozen and fresh urine specimens.
Cross reactivity and interference studies were performed on viral and bacterial strains commonly found in human urine. None of the organisms interfered or cross-reacted with the performance of the SAS™ Legionella Test.
