Test Catalog

Test ID: FIBR    
Fibroblast Culture for Biochemical and Molecular Testing, Tissue

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 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 Once grown to confluency, the cultures are expanded and then, if indicated, cryopreserved.(Unpublished Mayo method)

PDF Report Indicates whether the report includes an additional document with charts, images or other enriched information


Day(s) Performed Outlines the days the test is performed. This field reflects the day that the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time before the test is performed. Some tests are listed as continuously performed, which means that assays are performed multiple times during the day.


Report Available The interval of time (receipt of sample at Mayo Clinic Laboratories to results available) taking into account standard setup days and weekends. The first day is the time that it typically takes for a result to be available. The last day is the time it might take, accounting for any necessary repeated testing.

40 to 45 days

Specimen Retention Time Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded

3 years minimum-Check with lab for availability

Performing Laboratory Location Indicates the location of the laboratory that performs the test
