To perform the NADAL Norovirus GI/GII Test, follow these steps:
1. Specimen Collection and Preparation:
- Use clean, dry specimen collection containers for specimen collection.
- Collect approximately 50 mg of xxxx (equivalent to ¼ of a pea) for solid specimens or collect a fecal specimen and add 2 drops (approx. 80 µL) to the specimen collection tube containing buffer for liquid specimens.
- Shake the specimen collection tube to thoroughly mix the specimen and buffer.
2. Test Procedure:
- Bring the test cassette and samples with buffer to room temperature (15-30°C).
- Remove the test cassette from the sealed foil pouch and label it with the patient or control identification.
- Shake the specimen collection tube to ensure good sample dispersion.
- Dispense 2 drops of the solution from the specimen collection tube into the sample well (S) of the test cassette. Avoid trapping air bubbles and do not add any solution to the result area.
- Start the timer and wait for the colored lines to appear.
- Read the test result after 10 minutes but not more than 20 minutes.
3. Result Interpretation:
- Positive for norovirus genogroup I (GI): One green line in the control line region (C) and one red line in the test line region (GI).
- Positive for norovirus genogroup II (GII): One green line in the control line region (C) and one red line in the test line region (GII).
- Positive for norovirus genogroup I and II (GI and GII): One green line in the control line region (C), and a red line in each test line region (GI and GII).
- Negative: One green line in the control line region (C), and no line in either test line region (GI or GII).
- Invalid: The green control line (C) fails to appear. Repeat the test with a new test cassette.
Please note that the NADAL Norovirus GI/GII Test is intended for professional use only, and it is important to carefully follow the test procedure outlined in the instruction manual for accurate results.
