Autonomic Testing Lab
A state-of-the-art autonomic testing lab is available at Brigham and Women’s Faulkner Hospital. The lab offers one of the most comprehensive evaluations available throughout New England and the United States.
Autonomic nervous system testing helps to determine the presence, severity and localization of autonomic dysfunction and related small fiber neuropathy. It also helps to assess the cerebral blood flow. The Autonomic Lab at Brigham and Women’s Faulkner Hospital employs the Brigham Protocol, which has the following components:
A Physician’s order is required to schedule the appointment. Your physician can order the testing within the Mass General Brigham system (via Epic; use “Name of Standard order”) or complete this order and fax it to 617-983-7195.
You will receive an automated link to self-schedule the appointment via Patient Gateway or a phone call from our scheduling department once we receive the order.
Please note due to high volume of studies being requested at this time, our first available appointments may be as much as 11 months in the future.
Once you schedule the appointment via Patient Gateway, you will also be provided with an option to be added to a waitlist if you are able to fill a same day or next day cancellation appointment slot. Please follow the Patient Gateway instructions if you would like to be included in this option.
If you are having trouble using the Patient Gateway system to schedule this appointment, please call our Central Scheduling department at 617-983-7160. If you do not have a Patient Gateway account, please enroll here.
All autonomic studies will be interpreted and available within five to six weeks of the completed study.
Autonomic testing lasts between 60-90 minutes. This is a diagnostic appointment only. This is not a provider visit or consultation.
Avoid drinking alcohol, caffeinated beverages and smoking one day prior to testing. You can have a normal meal before testing. Do not use lotion or oils on legs or arms day of testing. Wear a loose fitting short-sleeve top and bring a change of shorts.
In general, medication that is used for dysautonomia should be put on hold. This medication includes blood pressure medication, medication for abnormal heart rate, and certain pain medications (amitriptyline, nortriptyline, elavil).
Do not stop any of your medication by yourself! Always ask your physician about what medications you should stop taking before testing.
Autonomic testing consists of deep breathing exam, valsalva maneuver, cranial Doppler (blood flow), sweat test, tilt test and/or skin biopsy.
We do not administer any medication during testing. However, for the skin biopsy we do give a Lidocaine injection to numb the sites we take the sample from. If patients are allergic to Lidocaine we do offer a cold spray to freeze the area before taking the sample.
It is imperative that you let us know your allergies prior to your visit!
Lidocaine with epinephrine is the only medication we give topically for the skin biopsy. If a patient is allergic to epinephrine we have a pure lidocaine alternative. For patients allergic to lidocaine we can use the cold spray. For patients with Latex allergies we offer Latex-free dressings (such as paper tape).
Yes, there is a weight limit. Patients over 350 lbs. are unable to be tested.
The skin biopsy is 2 to 3mm wide and deep, it does not require stitching (just a regular bandage). You should keep the biopsy site dry for 1 week, so please schedule your testing accordingly. We are recommending avoiding bathing/swimming for 1 week. For showering, you might cover the biopsy site with an elastic bandage to keep it dry.
Right after testing you can resume all regular activities including driving but if you have concerns feel free to bring someone with you.
Test results take approximately 5-6 weeks. No testing results will be provided on the day of your visit.
Cancellations should be made 24 hours or more prior to your scheduled test date by calling 617-983-7104.
Yes, we recommend checking with your insurance company prior to testing to ensure the procedure is covered and the facility is in network. For procedure codes and/or NPI numbers please call 617-983-7104.
