Expected Results:
Titers of Q-Fever Phase 1 and Q-Fever Phase 2 present
Comments
Single phase II IgG titers of 1:256 and greater are considered evidence of C. burnetii infection at some time prior to the date of the serum specimen. Phase I antibody titers of 1:16 and greater are consistent with chronic infection or convalescent phase of Q-fever.
