Answer

Titers higher than 1:160 in conjunction with a compatible clinical presentation are considered highly suggestive of infection. Titers higher than 1:320 are considered to be more specific, especially in endemic areas. Seroconversion and evolution of the titers can also be used for diagnosis.
