What is muscle biopsy?

A muscle biopsy is a procedure used to diagnose diseases involving muscle tissue. Your healthcare provider will remove tissue and cells from a specific muscle and view them microscopically. Your provider will only need to remove a small piece of tissue from the designated muscle.

What are the reasons for a muscle biopsy?

A muscle biopsy may be done to help identify or detect:

• Inflammatory diseases of muscle (such as polymyositis or dermatomyositis)
• Diseases of the connective tissue and blood vessels (such as polyarteritis nodosa)
• Infections that affect the muscles (such as trichinosis or toxoplasmosis)

Is a muscle biopsy considered surgery?

A muscle biopsy is a minor surgical procedure, which involves removing a small piece of muscle for analysis. There are two types of muscle biopsy; open biopsies and needle biopsies. These are usually performed under a local anaesthetic but a general anaesthetic is sometimes used, particularly in children.

Who orders muscle biopsy?

Your doctor may order a muscle biopsy for various reasons. They may suspect you have: a defect in the way your muscles metabolize, or use, energy. a disease that affects blood vessels or connective tissue, such as polyarteritis nodosa (which causes the arteries to become swollen)

How painful is muscle biopsy?

There is usually little or no pain during this test, but you may feel an uncomfortable tugging. Some people, however, report more pain depending on the size of the muscle sample taken. If you have an open biopsy, you may feel more pain than with a needle biopsy because of the amount of muscle tissue removed.

Does a biopsy hurt?

A small amount of anesthetic numbs the skin, allowing the procedure to be almost painless. At most a biopsy feels like a slight pinch as the anesthetic is being injected. You shouldn’t feel any sensation as the tissue is removed.

Understanding these specific features can also help guide treatment. The biopsied area should heal within a week or two.

How does a muscle biopsy diagnose muscular dystrophy?

Your doctor may do a muscle biopsy diagnose neuromuscular disorders, infections that affect your muscle, and other abnormalities in your muscle tissue. These are some conditions diagnosed by muscle biopsy: Muscular dystrophy (MD). A broad term that describes a genetic (inherited) disorder of the muscles.

What kind of strength is needed for muscle biopsy?

Choosing a muscle with MRC grade 4/5 strength is often sufficient and provides tissue that reveals the disease and not just end-stage morphology.

How long does it take to get results from muscle biopsy?

If you’re having an open biopsy, you may receive a general anesthesia. This means you will be sound asleep throughout the procedure. After the tissue sample is taken, it’s sent to a laboratory for testing. It could take up to a few weeks for the results to be ready.
