Muscle Biopsies

A muscle biopsy must be scheduled with the Department of Pathology at least one day prior to collection. For optimal results, please schedule the biopsy Monday-Thursday between 7:30am-2:30pm due to Fed Ex delivery and hours of acceptance at Mayo Clinic. Once the biopsy is obtained, it should immediately be sent fresh to the Department of Pathology with accompanying pertinent clinical history. Tissue will be snap frozen at Cottage Hospital and subsequently sent for all pathologic analysis and further processing at Mayo Clinic at the following address:
