|TEST INFORMATION:||Test includes routine morphologic diagnosis. Special tests as requested by physician.|
|TURNAROUND TIME:||48 hours to 7 days|
|CONTAINER TYPE:||Sterile specimen container|
Routine histology, histochemistry, and electron microscopy: Submit specimen fresh in saline-moistened gauze. Deliver to Laboratory Receiving Station, Rm 508 Jelke immediately after tissue is removed.
|SPECIMEN REQUIREMENTS:||Skeletal muscle|
|REJECTION CRITERIA:||Improper fixation, improper or discrepant labeling, O.R. specimens with invalid "barcode" ID label|
|MINIMUM VOLUME:||10 mm x 10 mm x 10 mm segment of muscle|
|HANDLING INSTRUCTIONS:||Deliver specimen to the laboratory immediately after removal.|
Special studies (histochemistry and/or electron microscopy) are required for most other muscle diseases (mitochondrial, lipid, glycogen myopathies). In certain diseases, an additional sample for enzyme assay or genetic analysis may be indicated; in this case, additional muscle should be snap frozen in the operating room. Liquid nitrogen for freezing may be obtained in Rm 508 Jelke.
All muscle biopsies are sent to Dr. R. Wollman at U of C (773-702-6166)
