Respiratory Syncytial Virus (RSV) Antibodies, IgG and IgM (Separate Determinations), Serum
Method Description Describes how the test is performed and provides a method-specific reference
The indirect immunofluorescence test is used for the measurement of IgG and IgM antibodies to respiratory syncytial virus (RSV). Specific antibodies present in the serum of the patient react with RSV infected cells that have been previously fixed on a glass microscope slide. Fluorescein-labeled anti-human IgG or IgM conjugate is used to stain specific antibody bound to the substrate cells. The slides are examined with a fluorescence microscope for the characteristic apple-green fluorescence of the infected cells.(Urquhardt GE, Walker GH: Immunofluorescence for routine diagnosis of respiratory syncytial virus infection. J Clin Pathol 1972;25:843-845)
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.
Tuesday, Friday; 9 a.m.
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.
Same day/1 day
Maximum Laboratory Time Defines the maximum time from specimen receipt at Mayo Medical Laboratories until the release of the test result
Specimen Retention Time Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded
Performing Laboratory Location The location of the laboratory that performs the test
