Test ID: FFAPL
Febrile Antibodies Panel
NY State Approved 
Indicates the status of NY State approval and if the test is orderable for NY State clients.
Reflex Tests Lists test(s) that may or may not be performed, at an additional charge, depending on the result and interpretation of the initial test(s)
| Test ID | Reporting Name | Available Separately | Always Performed |
|---|---|---|---|
| FRMFG | RMSF IgG Titer | No | No |
| FRMFM | RMSF IgM Titer | No | No |
| FRTG | R. Typhi IgG Titer | No | No |
| FRTM | R. Typhi IgM Titer | No | No |
| FBRAG | Brucella Agglutination | No | No |
Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.
If RMSF IgG is Detected, then FRMFG RMSF IgG Titer will be performed at an additional charge.
If RMSF IgM is Detected, then FRMFM RMSF IgM Titer will be performed at an additional charge.
If R. Typhi IgG is Detected, then FRTG R. Typhi IgG Titer will be performed at an additional charge.
If R. Typhi IgM is Detected, then FRTM R. Typhi IgM Titer will be performed at an additional charge.
If Brucella IgM is > or =1.10, then FBRAG Brucella Agglutination will be performed at an additional charge.
Method Name A short description of the method used to perform the test
Immunofluorescence Assay (IFA)
Enzyme Immunoassay (EIA)
Reporting Name A shorter/abbreviated version of the Published Name for a test; an abbreviated test name
Specimen Type Describes the specimen type needed for testing
Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.
Draw blood in a plain, red-top tube(s) or serum gel tube(s). Spin down and send 3 mL of serum refrigerated.
Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.
Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected
| Hemolysis | NA |
| Thawing | Warm OK; Cold OK |
| Lipemia | NA |
| Icterus | NA |
| Other | NA |
Specimen Stability Information Provides a description of the temperatures required to transport a specimen to the laboratory. Alternate acceptable temperature(s) are also included.
| Specimen Type | Temperature | Time |
|---|---|---|
| Serum | Refrigerated (preferred) | 14 days |
| Frozen | 30 days | |
| Ambient | 7 days |
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.

Day(s) and Time(s) Test Performed Outlines the days and times the test is performed. This field reflects the day and time the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time required before the test is performed. Some tests are listed as continuously performed, which means assays are performed several times during the day.
Varies; Monday through Friday
Analytic Time Defines the amount of time it takes the laboratory to setup and perform the test. This is defined in number of days. The shortest interval of time expressed is "same day/1 day," which means the results may be available the same day that the sample is received in the testing laboratory. One day means results are available 1 day after the sample is received in the laboratory.
Maximum Laboratory Time Defines the maximum time from specimen receipt at Mayo Medical Laboratories until the release of the test result
Performing Laboratory Location The location of the laboratory that performs the test
CPT Code Information Provides guidance in determining the appropriate Current Procedural Terminology (CPT) code(s) information for each test or profile. The listed CPT codes reflect Mayo Medical Laboratories interpretation of CPT coding requirements. It is the responsibility of each laboratory to determine correct CPT codes to use for billing.
