The results of the Weil-Felix test are interpreted based on the agglutination patterns observed with different Proteus antigens: - Positive result: Significant agglutination with one or more Proteus strains suggests a rickettsial infection. - Negative result: Lack of agglutination indicates the absence of detectable antibodies against rickettsial bacteria.
The interpretation should be done cautiously, considering clinical symptoms and other diagnostic information to avoid misdiagnosis.
