Which test confirms the type of muscular dystrophy?

Explanation:
To confirm the specific type of muscular dystrophy, you need to identify the exact genetic mutation causing it. Genetic testing directly looks for the disease-causing mutations in the known MD genes, which lets clinicians name the subtype and guide prognosis and management. Other tests can support a diagnosis—EMG helps distinguish a myopathy from nerve problems, and a muscle biopsy can show dystrophic changes and sometimes hint at a deficiency like dystrophin—but they do not by themselves identify the precise genetic form. Urine analysis is not used to determine MD type. Thus, genetic testing is the best test to confirm the type.
