This is a test that uses sound waves to look at the the carotid arteries in your neck. The carotid arteries carry blood to your brain. 

What are they looking for? Plaque buildup, narrowing of the arteries, blockages, and how well blood is flowing. 

What actually happens?   You lie on your back. Gel is placed on your neck and the technician will move a small device called a trasducer over your neck. The ultrasound machine creates picture of your arteries and measures blood flow. This testing is not usually painful. You may feel some pressure from the trasducer.

How should I prepare for my test? Do not smoke, exercise, or drink caffine prior to the test. Wear comfortable clothing that allows easy access to your neck.

This is a test to see how well your nerves and muscles are working. Thing of your nerves like electical wires: Brain-> nerve -> muscle -> movement. The test checks whether those electrical signals are traveling normally. 

What are they looking for? We are looking for things such as: Nerve damage, a pinched/compressed nerve, carpal tunnel, peripheral neuropathy, problems coming from the spine/nerve roots, certian nerve-to-muscle communication problems. 

The results of these test can help determine whether suymptoms such as numbess, tingling, weakness, pain, or muscle twitching are coming from a nerve, muscle, or the connection  between them .

Nerve Conduction Study (NCS) looks at how fast signals travel through your nerves. How strong those signals are, and whether a nerve is damaged or being compressed. 

What actually happens during a NCS?  They put small electrodes on your skin and give the nerve tiny electrical pulses. It can feel like a quick little zap or tapping sensation. It measures how quickly and strongly your nerve responds. The electrical pulses can be uncomfortable and cause some brief discomfort. Your muscles my be a little sore afterward.

Electromyography (EMG): Looks at electrical activity inside your muscles. What the muscle does while relaxing and what happens when you contract the muscle. 

What actually happens during an EMG? A very thin needle electrode is placed into certain muscles. You'll be asked to relax the mescle and then contract it. The machine records the muscle's electrical activity.  The electrical pulses can be uncomfortable and cause some brief discomfort. Your muscles my be a little sore afterward, sometimes with minor bruising from the needle. 

How should I prepare for my NCS/EMG? Shower/bathe beforehand. Do not apply lotion, moisturizer, oils, sunscreen, or perfume on the areas being tested. Wear loose comfortable clothing. 

If your arms and legs will be tested, please wear a short-sleeved shirt and shorts, when possible, to allow for easy access to the areas being tested.

The technician may ask you to open/close your eyes, breath deeply, look at flashing lights, and sleep dependning on the reason for the testing. 

Is it painful? No, the electrodes record your brain activity. They do not send electricity into your brain. 

How do I prepare for my test? On the day of your testing, please arrive with freshly washed hair. Do not apply hair products such as gels, oils, sprays, or other styling products, as these may interfere with electrode placement and electrical conductivity, which can affect the accuracy of your test results.

Were you ordered to have laboratory testing completed at your last visit? At checkout, we provide patients with a printed laboratory order. Patients are responsible for taking the lab order to their preferred laboratory for testing, as our office does not submit laboratory orders electronically. If you have misplaced your laboratory order, you are welcome to stop by our office to pick up a new copy.

How can I prepare for my blood draw? If your lab order includes a lipid panel or certain vitamin tests, including Vitamin B1, Vitamin B6, Vitamin B12, or Vitamin D, you will be required to fast for 10–12 hours prior to having your blood drawn.

During the fasting period, please do not eat or drink anything other than plain water, unless you have been given different instructions by your healthcare provider.

Thank you for following these instructions to help ensure accurate laboratory results.


 All medication refill requests must be submitted directly to our office by the patient. Refill requests may take 24–72 hours to process and complete, so we ask that you submit your request in advance to allow adequate time for processing.

Please be aware that refill requests submitted directly through the pharmacy may not always be received by our office. To help prevent delays or missed requests, we ask that all medication refills be called in or submitted directly to our office by the patient. This ensures that we receive the request and can process the refill appropriately.

Please also note that patients are required to have been seen in our office within the past 6–12 months in order for medications to be prescribed or refilled. If you have not been seen within this timeframe, an appointment may be required before your medication can be renewed.
