Test ID: FIL
Filaria, Blood
Method Description 
Describes how the test is performed and provides a method-specific reference
Unstained whole blood is first examined microscopically in search of motile microfilariae. Portions of the specimen are concentrated by centrifugation after adding 2% formalin. The sediment is examined as a wet preparation, and, if positive, the slide is air dried, fixed in methyl alcohol, and stained with Giemsa to aid in species identification.

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.
Monday through Friday; 3 p.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.
1 day
Maximum Laboratory Time Defines the maximum time from specimen receipt at Mayo Medical Laboratories until the release of the test result
4 days
Specimen Retention Time Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded
until reported
