Testing Algorithm
This processing test is for culturing skin fibroblasts or other biopsies for biochemical or molecular genetic studies. No analysis or interpretation of results is performed.
When this test is ordered, cryopreservation will always be performed at an additional charge. However, for multiple assays on a patient utilizing the ordered fibroblast culture, only one culture is required regardless of the number of assays ordered.
Once confluent flasks are established, the cultures are sent to other laboratories, either within Mayo Clinic Laboratories or to external sites, based on the specific testing requested. To avoid delays, indicate testing to be performed and provide external lab paperwork for send out testing.
If viable cells are not obtained within 30 days, client will be notified.
Mycoplasma screening will be performed on all successfully grown fibroblast cultures. If Mycoplasma is detected, all pending fibroblast clinical testing will be cancelled, and the samples will be discarded.
Specimen Type
TissueOrdering Guidance
This test is most useful for skin biopsy specimens. The specimen is cryopreserved for a minimum of 3 years.
This test is not appropriate for products of conception (POC) or chorionic villus sampling (CVS) specimens. If this test is ordered for either a POC or CVS specimen, the test will be canceled and CULFB / Fibroblast Culture for Genetic Testing, Tissue will be performed as the appropriate test.
Necessary Information
1. Include patient clinical history with request. This information will be used for any testing performed on the cultured cells.
2. Indicate the tests to be performed on the fibroblast culture cells. If send out testing is requested, the external lab paperwork must be submitted.

Clinical Information
Cultures of skin fibroblasts are useful for specialized tests requiring skin cells. These cells can be cultured and tested at Mayo Clinic Laboratories or sent to external laboratories performing these specialized tests. In addition, cells are frozen for a minimum of 3 years for potential future studies on cultured cells or for molecular genetic testing.
