Giardia lamblia Rapid Test Kit(Immunochromatographic Assay) – Bioantibody

Product details

Intended Use
Giardia lamblia Rapid Test Kit (Immunochromatographic Assay) is suitable for in vitro qualitative detection of Giardia antigens in human feces specimens to aid in the diagnosis of giardiasis.

Test Principle
Giardia lamblia Rapid Test Kit (Immunochromatographic Assay) is a lateral flow chromatographic immunoassay. It has two pre-coated lines, “T” Test line and “C” Control line on the nitrocellulose membrane. During testing, sample is applied into the sample well on the device. Giardia antigens, if present in the specimen, react with anti-Giardia antibodies coated colloidal gold particles in the test strip. The mixture then migrates upward on the membrane chromatographically by capillary action and reacts with anti-Giardia antibodies on the membrane in the test line region.

Operation Flow

1.Remove a test cassette from the foil pouch and place on a flat surface.
2.Unscrew the sample bottle, use the attached applicator stick attached on the cap to transfer small piece of stool sample (3-5 mm in diameter; approximately 30-50 mg) into the sample bottle containing specimen preparation buffer.
3. Replace the stick into the bottle and tighten securely. Mix stool sample with the buffer thoroughly by shaking the bottle for several times and leave the tube alone for 2 minutes.
4. Uncrew the sample bottle tip and hold the bottle in a vertical position over the sample well of the Cassette, deliver 3 drops (100 -120μL) of diluted stool sample to the sample well.
5. Read the results in 15-20 minutes. The result explanation time is not more than 20 minutes.

Result Interpretation

Negative result
Colored band appear at control line (C) only. It indicates that there are no Giardia antigens in human feces specimens or the number of Giardia antigens is below the detectable range.

Positive Result
Colored bands appear at both test line (T) and control line (C). It indicates a positive result for the detection of Giardia antigens in human feces specimens.

Invalid Result
No visible colored band appears at control line after performing the test. Insufficient sample volume or incorrect procedural techniques are the most likely reasons for control line failure. Review the test procedure and repeat the test using a new test device.
