Method Description Describes how the test is performed and provides a method-specific reference
Submitted biopsy specimens are minced, placed in a culture flask with additional culture media supplemented with fetal calf serum, and incubated. When the fibroblasts have grown from the pieces of tissue (2-4 weeks), the cultures are expanded and then, if indicated, cryopreserved (CRYOB / Cryopreservation for Biochemical Studies). If specific molecular or biochemical testing is concurrently ordered, cells will be harvested or prepared for indicated testing. Submitted cultured cells are examined for cell integrity and fed fresh media. Once grown to confluency, the cultures are expanded and then, if indicated, cryopreserved (CRYOB / Cryopreservation for Biochemical Studies). If specific molecular or biochemical testing is concurrently ordered, cells will be harvested or prepared for indicated testing.(Unpublished Mayo method)
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.
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.
40-45 days depending on rapidity of growth
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
