Giardia lamblia Antibodies Panel by ELISA

Also known as: GIA PAN

Clinical Use

Order Test

Use

This test is designed to detect antibodies (IgA, IgG, and IgM) specific to Giardia lamblia, which is a protozoan parasite causing giardiasis. The presence of these antibodies indicates exposure to the parasite and may support the clinical diagnosis of giardiasis, particularly in patients with gastrointestinal symptoms or a history that suggests potential exposure to contaminated water or food sources. This test aids in differentiating current from past infections based on the combination of antibody types detected.

Special Instructions

The test is performed at a non-ARUP laboratory, BioAgilytix Diagnostics, which is CLIA certified and CAP accredited. Separate specimens need to be submitted if multiple tests are ordered since this test is not processed at ARUP. The test is not approved for use in New York state, and samples from New York should not be submitted to ARUP.

Limitations

This test is not FDA approved or cleared, but it has been validated for clinical use by BioAgilytix Diagnostics. The results should be interpreted in conjunction with the patient's clinical presentation, other diagnostic tests, and exposure history. As with any antibody test, previous exposure and potential cross-reactivity should be considered when interpreting results. Negative results do not rule out the possibility of infection, and the timing of specimen collection in relation to disease onset may impact results.
