The muscle biopsy must be sent “fresh” in an enclosed container to prevent drying out with slightly moistened saline gauze wrapped around the specimen. Do not submerge the samples in saline as this will cause a swelling artifact. Also, do not let the sample dry out which will cause enzyme activity to be lost. The specimen must remain in a refrigerated state immediately after biopsy and throughout transportation.
