In chronic localized Brucellosis, standard tube agglutination test
titers may be low due to prozone phenomenon which indicates the presence of immunoglobulin A and G blocking antibodies.
In addition, the most common testing method-serology using the microscopic agglutination test
(MAT)-is so complex that it can take up to a week for results and is only performed at university or commercial laboratories.
Serum iodine agglutination test
(IAT) (6) was positive or strongly positive in 20 sick raccoon dogs that were 7 and 19 months old but was negative in healthy animals.
In this study, serum samples of 53 wild animals from 2 different states from the southeast region of Brazil were analyzed for the presence of anti-Toxoplasma gondii antibodies by the modified agglutination test
(MAT), with a cut-off of 1:5 for birds and of 1:25 for mammals.
Demonstration of granulocyte antibodies must be performed by using a minimum of 2 methods, the granulocyte agglutination test
(GAT), the indirect granulocyte immunofluorescence test (GIFT), or the monoclonal antibody-specific immobilization of granulocyte antigen (MAIGA) assay (Table 2).
The male infertility market is segmented based on techniques, namely DNA fragmentation, oxidative stress analysis, sperm agglutination test
, sperm penetration test, microscopic examination, computer assisted semen analysis and others.
All the samples were tested for the presence of anti-DENV, anti-chikungunya virus (CHIKV) IgM antibodies by IgM capture ELISA kits developed by National Institute of Virology (NIV), Pune (10), and anti-leptospiral antibodies by in-house developed microscopic agglutination test
(MAT) with a panel of known endemic antigens (11).
titers of>1:160 in blood or any positive titer in CSF); 4) clinical improvement after starting an appropriate treatment; 5) inability to prove a more suitable alternative diagnosis.
However, blood serology with indirect agglutination test
was negative for echinococcal disease.
The microscopic agglutination test
(MAT) is the gold standard test but requires significant expertise to maintain and interpret.
Indirect agglutination test
was done between cervicovaginal secretions and sperm of the participats' husbands for the detection of antibodies against sperm in cervicovaginal secretions.
Two tests have a role in veterinary diagnosis: the microscopic agglutination test
and ELISA .
