Description
Estimated cost for Muscle Biopsy at general public hospitals in China is about ¥560-2000, and at Grade 3A hospitals about ¥800-2500, varying by hospital tier and region.
Main Uses
The primary purpose of a muscle biopsy is to diagnose neuromuscular disorders, including inflammatory myopathies, muscular dystrophies, metabolic myopathies, and mitochondrial myopathies. It is also used to assess the extent of muscle damage in various conditions and to guide treatment decisions.
Normal Range
A muscle biopsy does not have a standard numerical range like blood tests. Instead, the normal findings are characterized by the absence of abnormalities in muscle fiber size, shape, and arrangement, as well as no signs of inflammation, necrosis, or abnormal glycogen, lipid, or mitochondrial accumulation.
Low Values - Possible Causes
Muscle biopsies do not produce 'low' values; however, under certain conditions, such as atrophy, there might be observed smaller than normal muscle fibers, which can be due to: disuse, neurogenic disorders, malnutrition, or chronic diseases leading to muscle wasting.
High Values - Possible Causes
Similarly, 'high' values are not applicable, but increased presence of certain indicators may suggest: inflammation (myositis), metabolic myopathies (abnormal storage of glycogen or lipids), muscular dystrophies (degeneration and regeneration of muscle fibers), or mitochondrial myopathies (abnormalities in mitochondria).
