Antibodies to myoglobin can be employed to identify myoglobin-containing casts within renal tubules, which can be seen following rhabdomyolysis and in cases of myoglobin cast nephropathy.
Myoglobin is NOT recommended as a marker of rhabdomyosarcoma, as much more sensitive markers such as myogenin, myoD1, and desmin are best employed in this setting.
Clinical Indication(s): This anti-myoglobin antibody will be used to identify the presence of myoglobin-containing tubular casts in the lumina of renal tubules.
