Reference Values Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.

Rickettsia (Typhus Fever) Antibodies (IgG, IgM) with Reflex to Titers

 Reference Range: Not Detected

 

Rickettsia (RMSF) Antibodies (IgG, IgM) with Reflex to Titers

 Reference Range: Not Detected

 

Salmonella Antibodies, EIA

 Reference Range: Not Detected

 

Antibodies to Salmonella flagellar (H) and somatic (O) antigens typically peak 3 – 5 weeks after infection. A positive results in this assay is equivalent to a titer of >=1:160 by tube agglutination (Widal). Results should not be considered as diagnostic unless confirmed by culture.

 

Brucella Antibodies (IgG, IgM), EIA with Reflex to Agglutination

 Reference Range: <0.80

 

 Interpretive Criteria:

            <0.80 Antibody not detected

            0.80 – 1.09 Equivocal

            > or = 1.10 Antibody detected

 

Acute brucellosis is characterized by the appearanceof Brucella-specific IgM within the first week of infection, followed by the appearance of Brucella-specific IgG after the second week. Levels of both IgM and IgG decline slowly over several months in conjunction with recovery. Persistence of high IgG levels with declining or absent IgM suggests chronic infection or relapse.
