Special Instructions
Cautions
Serology results for IgG may be negative during the acute phase of infection (<7 days post-symptom onset), during which time detection using targeted nucleic acid amplification testing (eg, polymerase chain reaction) is recommended.
Detectable IgG-class antibodies typically appear within 7 to 10 days post-symptom onset.
IgG-class antibodies may remain detectable for months to years following prior infection. Therefore, a single time point-positive titer needs to be interpreted alongside other findings to differentiate recent versus past infection.
Other members of the Ehrlichia genus (eg, Ehrlichia ewingii) may not be detected by this assay.
