One Step Giardia lamblia Antigen Rapid Test Device
The Giardia lamblia Antigen Rapid Test Device (Feces) is a rapid visual immunoassay for the qualitative, presumptive detection of Giardia lamblia in human fecal specimens. This kit is intended for use as an aid in the diagnosis of Giardia lamblia infection.
The Giardia lamblia Antigen Rapid Test Device (Feces) detects Giardia lamblia through visual interpretation of color development on the internal strip. Anti-Giardia lamblia antibodies are immobilized on the test region of the membrane. During testing, the specimen reacts with anti-Giardia lamblia antibodies conjugated to colored particles and precoated onto the sample pad of the test. The mixture then migrates through the membrane by capillary action and interacts with reagents on the membrane. If there is sufficient Giardia lamblia in the specimen, a colored band will form at the test region of the membrane. The presence of this colored band indicates a positive result, while its absence indicates a negative result. The appearance of a colored band at the control region serves as a procedural control, indicating that the proper volume of specimen has been added and membrane wicking has occurred.
Bring tests, specimens, buffer and/or controls to room temperature (15-30°C) before use.
1. Specimen collection and pre-treatment:
1) Use clean, dry containers for specimen collection. Best results will be obtained if the assay is performed within 6 hours after collection.
2) For solid specimens: Unscrew and remove the dilution tube applicator. Becareful 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 80 µL) into the specimen collection tube containing the extraction buffer.
3) Replace 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.
1) Remove the test from its sealed pouch, and place it on a clean, level surface. Label the test with patient or control identification. For best results, the assay should be performed within one hour.
2) Using a piece of tissue paper, break the tip of the dilution tube. Hold the tube vertically and dispense 3 drops of solution into the specimen well (S) of the test device.
Avoid trapping air bubbles in the specimen well (S), and do not add any solution to the result window.
As the test begins to work, color will migrate across the membrane.
3. Wait for the colored band(s) 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 due to the presence of particles, centrifuge the extracted specimens contained in the extraction buffer vial. Collect 100 µL of supernatant, dispense into the specimen well (S) of a new test device and start again, following the instructions described 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.
