Myogenin, technical only
Use
The Myogenin test is used to detect myogenic transcriptional regulatory protein expression, which occurs early in skeletal muscle differentiation. It is also expressed in rhabdomyosarcoma, a type of soft tissue sarcoma, making this test valuable in the diagnostic process of muscle-related tumors.
Special Instructions
Not provided.
Limitations
The test does not include a pathologist's interpretation. The expression of myogenin may be seen in several types of soft tissue tumors, which may result in diagnostic overlap. Specimens not fixed in the specified 10% neutral buffered formalin (NBF) may be rejected, limiting test availability.

Collection Instructions
Fixative should be at a 20:1 fixative to tissue ratio using 10% neutral buffered formalin (NBF) for 6-72 hours, with 48-72 hours being preferred. Specimens must be tested within 3 months after placing in ethanol.
