Testing Algorithm
When this test is ordered, cryopreservation for biochemical studies will always be performed at an additional charge. However, for multiple assays on a patient utilizing the ordered fibroblast culture, only 1 culture is required regardless of the number of assays ordered. 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.
Method Name
FIBR: Cultivated from Biopsy as Monolayer

Reporting Name
Fibroblast CultureSpecimen Type
TissueSubmit only 1 of the following specimens:
Specimen Type: Cultured fibroblasts
Container/Tube: T-75 or T-25 flask
Specimen Volume: 1 Full T-75 flask or 2 full T-25 flasks

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.
Specimen Type: Skin biopsy
Container/Tube: Sterile container with any standard cell culture media (eg, minimal essential media, RPMI 1640). The solution should be supplemented with 1% penicillin and streptomycin. Tubes of culture media can be supplied upon request (Eagle's minimum essential medium with 1% penicillin and streptomycin [T115]).

Clinical Information
Cultures of skin fibroblasts are useful for specialized testing, which requires skin cells. These cells can be cultured and tested at Mayo Clinic or sent to external laboratories performing these specialized tests. In addition, cells are frozen for at least 3 years for potential future studies on cultured cells or for molecular genetic testing.
Reference Values
Not applicable
Cautions
Potential interfering factors:
-Lack of viable cells
-Bacterial contamination
-Failure to transport tissue in an appropriate media
-Excessive transport time
-Exposure of the specimen to temperature extremes (freezing or >30° C)
-Improper packaging may result in broken or leaky specimen containers or contamination of specimens during transport
