Neuropathy Testing in Brigham City, Utah
Nerve damage in the feet often develops silently, which is why testing matters. At Corbridge Podiatry in Brigham City, Dr. Treg Corbridge and Dr. Christopher Funk offer neuropathy testing to detect nerve damage early and guide effective treatment before complications develop.
What is neuropathy testing?
Neuropathy testing can help diagnose small fiber neuropathy by measuring the density of nerve fibers in a small sample of your skin; a measure known as epidermal nerve fiber density (ENFD). Neuropathy is a peripheral nerve disease that selectively affects small-diameter nerve fibers. This test is highly specific and sufficiently sensitive, with a 97% accuracy rate.
Common causes of small fiber neuropathy include diabetes (types 1 and 2), HIV, vibratory trauma, amyloidosis or monoclonal gammopathy, alcohol abuse, pharmacologic toxins, solvent exposure, and idiopathic (unknown) causes. Our foot specialists specialize in neuropathy testing and can quickly diagnose the problem and set you on a path forward, working step-by-step with you toward the best possible results.
How is peripheral neuropathy diagnosed?
Peripheral neuropathy has many possible causes. Beyond a physical exam, which may include blood tests, diagnosis usually involves:
- A full medical history: Your provider reviews your symptoms, lifestyle, toxin exposure, drinking habits, and any family history of neurological disease.
- A neurological exam: Your provider may check tendon reflexes, muscle strength and tone, your ability to feel sensations, and your balance and coordination.
What tests might be ordered?
Depending on your situation, your Corbridge Podiatry foot specialist may order:
- Blood tests: To detect vitamin deficiencies, diabetes, inflammation, or metabolic issues that can cause neuropathy.
- Imaging tests: CT or MRI scans to look for herniated disks, pinched nerves, growths, or problems affecting blood vessels and bones.
- Nerve function tests: Electromyography (EMG) records electrical activity in the muscles to find nerve damage, usually alongside a nerve conduction study that measures how nerves respond to a small electric current.
- Other nerve function tests: Including an autonomic reflex screen, a sweat test, and sensory tests that record how you feel touch, vibration, cooling, and heat.
- Nerve biopsy: Removing a small portion of a sensory nerve to identify the cause of neuropathy.
- Skin biopsy: Removing a small portion of skin to count nerve endings.
Frequently Asked Questions
What are the early signs of neuropathy?
Numbness, tingling, burning, or a 'pins and needles' feeling in the feet are common early signs, as is reduced ability to feel temperature or injuries.
Why is early neuropathy testing important?
Catching nerve damage early allows treatment that can slow its progression and helps prevent serious complications like unnoticed wounds and diabetic ulcers.
Is neuropathy testing painful?
Most tests are minimally uncomfortable. Dr. Corbridge will explain each step beforehand and choose the least invasive tests appropriate for you.
I have diabetes. Should I be tested?
Diabetes is the most common cause of small fiber neuropathy, so testing is often recommended. Talk with us about whether it's right for you.
