Product Description

Intended Use

INTENDED USE
The Clostridium difficile GDH, Toxin A and Toxin B combo Rapid Test is a test for the detection of glutamate dehydrogenase antigen and toxins A and B. The test detects C. difficile antigen, glutamate dehydrogenase, as a screen for the presence of C. difficile, and confirms the presence of toxigenic C. difficile by detecting toxins A and B in stool specimens from people suspected of having C. difficile which is a difficult disease. The test will serve as an adjunct to the diagnosis of clostridium difficile. As with other C. difficile tests, the results should be considered in conjunction with the patient's medical history.

Test Procedure

TEST PROCEDURE

Bring tests, specimens, and/or controls to room temperature (15-30°C) before use.

1. Remove the test from its sealed pouch, and place it on a clean, level surface. Label the device with patient or control identification.
2. SPECIMEN PREPARATION:
3. ASSAY PROCEDURE:

• Tighten the cap onto the specimen collection tube, then shake the specimen collection tube vigorously to mix the specimen and the extraction buffer. Leave the tube alone for 2 minutes.
• Remove the small lid at the top.
• Hold the bottle in a vertical position over the sample well of the test card, deliver 3 drops (about 90μl) of diluted stool sample to the sample well (S) and start the timer.
• Wait for the colored band(s) to appear. Read the result between 5-10 minutes. A strong positive sample may show result earlier. Do not interpret the result after 15 minutes. As the test begins to work, color will migrate across the result area in the center of the device

INTERPRETATION OF RESULTS            

Clostridiumdificile GDH

 

Clostridium difficile Toxin A and Toxin B

• 
• Toxin A Positive : The colored line in the control line region (C) appears, and a colored line appears in test line region T1. The result is positive for Clostridium difficile Toxin A and is indicative of Clostridium difficile infection.
• Toxin B Positive: The colored line in the control line region (C) appears, and a colored line appears in test line region T2. The result is positive for Clostridium difficile Toxin B and is indicative of Clostridium difficile infection.
• Toxin A&B Positive:The colored line in the control line region (C) appears, and two colored lines should appear in test line regions T1 and T2. The color intensities of the lines do not have to match. The result is positive for Toxin A & Toxin B and is indicative of Clostridium difficile infection.
• Negative (-) : Only a purple red band appears in the quality control area (C). No purple red bands were found in the detection area (T1) and (T2). A negative result indicates no Clostridium difficile infection.
• Invalid: No purple red band in quality control area (C).
