Toxoplasma gondii IgG & IgM Antibody Panel (IFA)
The Toxoplasma gondii IgG & IgM Panel utilizes the indirect fluorescent antibody (IFA) method to detect antibodies against Toxoplasma gondii, a protozoan parasite that can infect cats and other animals, posing significant zoonotic risk. This panel differentiates between IgG and IgM antibodies, helping to assess the stage of infection. High IgM levels typically indicate recent or active infection, while IgG antibodies suggest prior exposure or chronic infection. Infected cats may present with various symptoms, including lethargy, fever, respiratory issues, and neurological signs, though many remain asymptomatic. The Toxoplasma gondii IgG & IgM Panel is particularly useful for evaluating cats with suspected toxoplasmosis, monitoring infection status, and managing transmission risks, especially in households with immunocompromised individuals.
2 ml Serum
Collect an adequate amount of blood in a plain red-top tube or serum separator tube (yellow-top tube). Allow it to clot at room temperature for 30 to 60 minutes before separation.
Centrifuge to separate the serum. Transfer the clear serum into a new, leak-proof plain red-top tube and label it as "serum."
Excessively hemolyzed samples are not suitable for this test.
Unspun samples will not be accepted.
Refrigerate sample at 4oC until shipment.
Label each sample with the animal’s name and a unique identifier, using a permanent marker or a secure adhesive label
Ensure the submittal form is completed with the animal’s information and relevant medical history.
