Result Interpretation

IgG  Neg: <1:64

IgM  Neg:<1:64

Spotted Fever Group IgG serum endpoint titer of >=1:64 is
suggestive of infection at an unknown time and may be a sign of
either past infection or early response to a recent infection.
Spotted Fever Group IgM titer of >=1:64 is regarded as probable
evidence of recent or ongoing infection. A four-fold or greater
increase in titer between two serum samples drawn 1-2 weeks apart
and tested in parallel is the best serologic indicator of a
recent rickettsial infection.
