gold colloidal method Rotavirus Rapid Diagnostic Cassette to detect rotavirus in human feces ,, easily and quick

Product Name:

Rotavirus Rapid Diagnostic test

Intended Use:

The Rotavirus Rapid Test Device (Feces) is a rapid visual immunoassay for the qualitative presumptive detection of rotavirus in human fecal specimens. This kit is intended to be used as an aid in the diagnosis of rotavirus infection.

Test Principle:

The Rotavirus Rapid Test Device (Feces) has been designed to detect rotavirus through visual interpretation of color development in the internal strip. The membrane was immobilized with anti-rotavirus antibodies on the test region. During the test, the specimen is allowed to react with colored anti-rotavirus antibodies colloidal gold conjugates, which were precoated on the sample pad of the test. The mixture then moves on the membrane by a capillary action, and interact with reagents on the membrane. If there were enough rotavirus in specimens, a colored band will form at the T region of the membrane. Presence of colored band indicates a positive result, while its absence indicates a negative result. Appearance of a colored band at the control region serves as a procedural control. This indicates that proper volume of specimen has been added and membrane wicking has occurred.

TEST PROCEDURE

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

Specimen collection and pre-treatment:

Use the specimen collection container for specimen collection. Best results will be obtained if the assay is performed within 6 hours after collection.

For solid specimens: Unscrew and remove the dilution tube applicator. Be careful not to spill or spatter solution from the tube. Collect specimens by inserting the applicator stick into at least 3 different sites of the feces to collect approximately 50 mg of feces (equivalent to 1/4 of a pea).

For liquid specimens: Hold the pipette vertically, aspirate fecal specimens, and then transfer 2 drops (approximately 50 µL) into the specimen collection tube containing the extraction buffer.

Place the applicator back into the tube and screw the cap tightly. Be careful not to break the tip of the dilution tube.

Shake the specimen collection tube vigorously to mix the specimen and the extraction buffer. Specimens prepared in the specimen collection tube may be stored for 6 months at -20°C if not tested within 1 hour after preparation.

Avoid trapping air bubbles in the specimen well (S), and do not drop any solution in observation window.

As the test begins to work, you will see color move across the membrane.

Wait for the colored band to appear. The result should be read at 10 minutes. Do not interpret the result after 20 minutes.

Note: If the specimen does not migrate (presence of particles), centrifuge the extracted specimens contained in the extraction buffer vial. Collect 80 µL of supernatant, dispense into the specimen well (S) of a new test device and start afresh following the instructions mentioned above.

INTERPRETATION OF RESULTS

POSITIVE:* Two lines appear. One colored line should be in the control line region (C) and another apparent colored line should be in the test line region (T).

*NOTE: The intensity of the color in the test line region (T) will vary depending on the concentration of TP antibodies present in the specimen. Therefore, any shade of color in the test line region (T) should be considered positive.

NEGATIVE: One colored line appears in the control line region (C). No line appears in the test line region (T).

INVALID: Control line fails to appear. Insufficient specimen volume or incorrect procedural techniques are the most likely reasons for control line failure. Review the procedure and repeat the test with a new test. If the problem persists, discontinue using the test kit immediately and contact your local distributor.
