The Strep A Rapid Test Strip (Throat Swab) is a rapid chromatographic immunoassy for the qualitative detection of Streptococcus pyogenes (Group A B-hemolytic Streptococcus, Strep A) antigen from throat swab specimens of symptomatic patients to aid in the diagnosis of Group A Streptococcus bacterial infection. All negative test results should be confirmed by bacterial culture because negative results do not prection with Group A Streptococcus and should not be used as the sole basis for treatment.

Healgen Strep A Rapid Test Strip (Throat Swab) is a qualitative, lateral flow immunoassay for the detection of Strep A antigen directly from a throat swab sample. In this test, antibody specific to Strep A carbohydrate antigen is coated on the test line region of the test. During testing, the extracted throat swab specimen reacts with an antibody to Strep A that is coated onto particles. The mixture migrates up the membrane to react with the antibody to Strep A on the membrane and generate a color line in the test line region. The presence of this color line in the test line region indicates a positive result, while its absence indicates a negative result. To serve as a procedural control, a colored line will always appear in the control line region, indicating that proper volume of specimen has been added and membrane wicking has occurred.

The Sofia Strep A+ FIA detects Group A Streptococcal antigens from patients with signs and symptoms of pharyngitis, such as sore throat. All negative test results should be confirmed by either bacterial culture or an FDA-cleared molecular assay because negative results do not prection and should not be used as the sole basis for treatment. The test is intended for professional and laboratory use as an aid in the diagnosis of Group A Streptococcal infection. The Sofia Strep A+ FIA may be used with Sofia or Sofia 2.

The Sofia Strep A+ FIA involves the extraction of the antigenic components of the Group A Streptococcus (GAS) bacteria. The patient's Swab sample is placed in the Reagent Tube containing the Reagent Solution, during which time the bacterial antigens are extracted, making them more accessible to the specific antibodies. An aliquot of the extracted sample is dispensed into the Test Cassette sample well. From the sample well, the sample migrates through a test strip containing various unique chemical environments. If Group A Streptococcal antigens are present, they will be bound by antibodies coupled to fluorescent microparticles that migrate through the test strip. The fluorescent microparticles containing bound antigen will be captured by antibodies at a defined location on the test strip where they are detected by Sofia or Sofia 2. If antigens are not present, the fluorescent microparticles will not be trapped by the capture antibodies nor detected by Sofia or Sofia 2. Depending upon the user's choice, the Test Cassette is either placed inside of Sofia or Sofia 2 for automatically timed development (WALK AWAY Mode) or placed on the counter or bench top for a manually timed development and then placed into Sofia 2 to be scanned (READ NOW Mode). Sofia or Sofia 2 will scan the test strip and measure the fluorescent signal by processing the results using method-specific algorithms. Test results will be displayed (Positive, or Invalid) on the screen. The results can also be automatically printed on an integrated printer if this option is selected. Sofia 2 is a microprocessor-controlled device about the size of a desk top telephone and weighs less than 3 pounds. Sofia 2 uses a fluorescent tag that is illuminated by an Ultraviolet (UV) light source to generate specific results.

The Sofia® Strep A+ FIA detects Group A Streptococcal antigens from patients with signs and symptoms of pharyngitis, such as sore throat. All negative test results should be confirmed by bacterial culture because negative results do not preclude Group A Strep infection and should not be used as the sole basis for treatment.

Note: The Cassette, now containing the sample, is placed directly inside Sofia for automatically timed development (WALK AWAY Mode). Sofia scans, measures, and interprets the immunofluorescent signal using method-specific algorithms. Sofia will display the test results (Positive, Negative, or Invalid) on the screen. The results can also be automatically printed on an integrated printer if this option is selected, or transmitted via an LIS connection.

Wondfo One Step Strep A Swab Test is a qualitative, lateral flow immunoassay for the detection of Strep A carbohydrate antigen directly from a throat swab sample. To perform the test. Reagent 1 (R 1) is added to the extraction tube which is coated with a mixture of conjugate antibodies and a lytic enzyme extraction reagent. The lytic enzyme is mixed with colloidal gold conjugated to rabbit anti-Strep A and a second colloidal gold control conjugate antibody. The reagents are dried onto the bottom of an extraction tube forming a red spot. The extraction/conjugate pellet is re-suspended with RI and the throat swab is added to the extraction tube. The Strep A antigen is extracted from the sample and the swab is removed. The test strip is immediately placed in the extracted sample. If Group A Streptococcus is present in the sample, it will react with the anti-Strep A antibody conjugated to the gold particle. The complex will then be bound by the anti-Strep A capture antibody and a visible red test line will appear, indicating a positive result. To serve as an onboard procedural control, the blue line observed at the control site prior to running the assay will turn red, indicating that the test has been performed properly. If Strep A antigen is not present, or present at very low levels, only a red control line will appear. If the red control line does not appear, or remains blue, the test result is invalid.

The Sofia Strep A FIA employs immunofluorescence technology that is used with the Sofia Analyzer to detect Group A Streptococcal antigens. The Sofia Strep A FIA is a lateral-flow immunoassay that uses polyclonal antibodies that are specific for Group A Streptococcal antigens. Throat swab specimens are used for this test. The patient specimen is placed in the Reagent Tube, during which time the bacteria in the specimen are disrupted, exposing Group A Streptococcal antigens. After disruption, the specimen is dispensed into the cassette sample well. From the sample well, the specimen migrates through a test strip containing various unique chemical environments. If the Group A Streptococcal antigen is present, they will be trapped in a specific location.

The Inverness Medical TestPack + Plus Strep A with OBC Test is intended for the qualitative detection of Group A Streptococcal (Group A Strep) antigen in throat swab specimens from patients with suspected Group A Strep associated pharyngitis and for confirmation of presumptive Group A Strep colonies isolated on culture plates. The test is intended for Professional and Laboratory Use only.

Inverness Medical TestPack + Plus Strep A with OBC Strep A is an immunoassay employing sheep and rabbit polyclonal antibodies and gold colloid particles. The test device uses lateral flow technology; following antigen extraction, the test time is approximately 5 minutes. The Streptococcal Group A specific antigen is extracted from the throat swab using Reagent 1 (2.0 M Sodium Nitrite (& Xylenol Orange) and Reagent 2 (1.0 M Acetic Acid). Following this, Reagent 3 (1.0 M Tris Buffer) is added to neutralise the acid formed by Reagents 1 and 2. The mixture is then dropped into the sample well of the reaction disc from which it migrates through the membrane until it reaches the End of Assay (EOA) Window. As the specimen extract migrates through the membrane, it mobilises the antibody-coated colloid (colloid coated with Rabbit Anti-Strep A antibody). If Group A Streptococcal antigen is present in the specimen it will form a complex with the antibody-colloid. The antibody colloid complex migrates through the membrane and is then captured by the Group A Strep antibody (Sheep polyclonal antibody) in the result window, providing a visual indication of the presence of antigen. The test can be read when the 'End of Assay' (EOA) window has turned pink / red. A pink / red Plus Sign (+) appearing in the result window indicates the presence of the Group A Strep antigen. A Minus Sign (-) indicates no antigen was detected. The device also includes integral Control features.
