*5.2.4 Indirect coombs test*

Incomplete, blocking, or non-agglutinating IgG can be detected with the help of the Coombs test, which is an extension of the SAT.

## *5.2.5 Brucella capt test*

When it comes to diagnosing human brucellosis, the *Brucella* capt test has been proposed as an alternative to the Coombs test. This is because it is an immune capture agglutination test. The BRUCAPT test is an immunocapture assay that can detect total anti-*Brucella* antibodies in a single step. The Coombs test was previously the only method for measuring agglutinating and incomplete antibodies; this assay allows the detection of both. To diagnose brucellosis, especially in its more advanced stages, and to monitor its treatment, this test is the gold standard of serological methods; quick and easy, the results will be available in 24 hours. The best possible sensitivity and specificity are achieved without subjecting samples to any kind of washing or dilution.
