SASTM Influenza A Test is a visual and rapid assay for the presumptive in-vitro qualitative detection of influenza A viral nucleoprotein antigens from nasal washes and nasal aspirates of symptomatic patients. The test is not intended for the detection of Influenza Type B viral antigen or Influenza Type C viral antigen. This test is for professional use only. Negative results do not preclude infection with influenza A and should not be used as the sole basis for treatment or other patient management decisions. It is recommended that negative results be confirmed by cell culture. SASTM FluAlert A & B Test is a visual and rapid assay for the presumptive in-vitro qualitative detection of Influenza A and Influenza B viral nucleoprotein antigens from nasal washes and nasal aspirates of symptomatic patients. The test is not intended for the detection of Influenza Type C viral antigen. This test is for professional use only. Negative results do not preclude infection with influenza A and/or influenza B and should not be used as the sole basis for treatment or other patient management decisions. It is recommended that negative results be confirmed by cell culture.

The SASTM Influenza A Test utilizes antibodies against influenza type A viral nucleoproteins. The SASTM Influenza A test begins with an extraction of Type A nucleoproteins. After the extraction has been completed, the sample is placed into the sample well of the test. The specimen is absorbed and migrates via capillary action through membranes that contain dried gold conjugated antibody, which is specific for influenza A viral nucleoproteins. If these nucleoproteins are present, a "half-sandwich" immunocomplex is formed. The membrane contains immobilized antibody to influenza A nucleoproteins, which binds the "half sandwich" complex. Thus, in the presence of influenza A nucleoproteins, a "whole sandwich" immunocomplex is formed and a visible, pink-colored line develops in the specimen zone of the test device. In the absence of an influenza A antigen, a "sandwich" immunocomplex 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 of each strip regardless of the presence or absence of influenza A nucleoproteins. The SASTM FluAlert A & B Test utilizes antibodies against influenza type A and influenza type B viral nucleoproteins. After the extraction has been completed, the sample is placed into two separate sample wells. The specimen is absorbed and migrates via capillary action through membranes that contain dried gold conjugated antibody, which is specific for either influenza A or influenza B viral nucleoproteins. If these nucleoproteins are present, a "half-sandwich" immunocomplex is formed. The membrane contains immobilized antibody to influenza A or influenza B nucleoproteins, respectively, which bind the "half sandwich" complex. Thus, in the presence of influenza nucleoproteins, a "whole sandwich" immunocomplex is formed and a visible, pink-colored line develops in the specimen zone of the test device. In the absence of an influenza antigen, a "sandwich" immunocomplex 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 of each strip regardless of the presence or absence of influenza A or influenza B nucleoproteins.

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.

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.
