Is there a snap test for Giardia?

Is there a snap test for Giardia?

Use the SNAP Giardia Test to identify the presence of Giardia in dogs and cats as an adjunct to a fecal flotation. The SNAP Giardia Test is the first USDA-approved in-house rapid assay for the detection of soluble Giardia antigen.

What does Giardia SNAP test detect?

The SNAP* Giardia Test Kit is a rapid enzyme immunoassay for the detection of Giardia antigen in canine and feline feces. The presence of this antigen in fecal samples indicates the animal has ingested Giardia cysts, may be actively infected, and may be shedding cysts in feces.

How accurate is the Giardia SNAP test?

The SNAP test was considered the reference method as the relative sensitivity and specificity compared with immunofluorescence microscopy has been reported to be 95% and 99%, respectively and compared with microplate ELISA to be 96% and 100%, respectively (SNAP Giardia Antigen Test Kit product insert).

How do you test for Giardia?

Interpreting test results: The test is positive if the color on the sample spot is darker than the color on the negative control spot. The test is negative if the color on the sample spot is = to or < the color on the negative control spot.

Can you get a false positive Giardia test?

If the risk of giardiasis is low, a negative result helps you rule out the disease, but a positive result is non-conclusive due to the high risk of false positive. However, if the risk of disease is high – for example, puppies from shelters or breeding colonies – a positive test will help confirm the diagnosis.

How long does it take to test for Giardia?

Getting the Results In general, the result of the Giardia antigen test is reported within a day.

What does a positive Giardia antigen test mean?

A test that detects Giardia antigens (positive result) means that the person has giardiasis. If the infected person does not have symptoms of infection, he or she may be a carrier or have a chronic infection.

What is the treatment for Giardia in dogs?

The most common drugs used to kill Giardia are fenbendazole and metronidazole. These drugs are normally given for three to ten days to treat giardiasis. Both drugs may be given in combination if necessary.

What is the best test for giardia?

Microscopy with direct fluorescent antibody testing (DFA) is considered the test of choice for diagnosis of giardiasis since it provides increased sensitivity over non-fluorescent microscopy techniques. Other alternate methods for detection include: Rapid immunochromatographic cartridge assays.

What do you feed a dog with giardia?

A dog who’s been diagnosed with giardia has a weakened, inflamed gastrointestinal system, so proper nutrition is an essential part of treatment. The vet will likely recommend feeding your dog a bland food that’s easy to digest and that promotes intestinal healing.

Can you cure Giardia without antibiotics?

Management and Treatment Many people with giardiasis have minor symptoms that go away on their own. You may not need treatment. If you have more severe parasite symptoms, your provider may prescribe an antibiotic with antiparasitic effect to kill the parasite.

What is Giardia antigen test?

Overview. For a giardia antigen test, a stool sample or fluid from the upper part of the intestines (duodenal fluid) is tested in the lab for the presence of antigens from Giardia lamblia. This test is often done at the same time as a stool analysis.

How does the snap test for Giardia work?

Giardia Use the SNAP Giardia Test to identify the presence of Giardia in dogs and cats as an adjunct to a fecal flotation. The SNAP Giardia Test is the first USDA-approved in-house rapid assay for the detection of soluble Giardia antigen.

How to test for giardia in dogs and cats?

The Companion Animal Parasite Council (CAPC) recommends testing symptomatic (intermittently or consistently diarrheic) dogs and cats with a combination of direct smear, fecal flotation with centrifugation, and a sensitive, specific fecal ELISA optimized for use in companion animals.

When to do a follow up test for Giardia?

See Tynes et al, 2014 for additional information. Follow up testing may be done 24-48 hours after the completion of therapy if clinical signs have not resolved. It is recommended to perform a fecal flotation with centrifugation primarily for detection of cysts in solid or semisolid stools.

What kind of stain is used to diagnose Giardia?

Commercially available fixative stains (e.g. Proto-fix™) are also useful for microscopic diagnosis. Polymerase Chain Reaction (PCR) assays can also be used to amplify Giardia species DNA in feces and are available in commercial laboratories.
