Expectations for each test can vary depending on the type of test you are getting done. Some tests, such as the ABI Test, use inflatable cuffs to gauge blood flow and pressure at various locations on the thigh, calf, foot, and toes. For ultrasound studies you can expect for ultrasound gel to be placed on the specific imaging regions of your body. Through the gel, the technician will apply a small hand-held device that emits sound waves which will get the desired images. Wearing clothing that makes access to the specific imaging areas easier is generally recommended. Additionally, you are typically not supposed to use powders, oils, or lotions on the imaging areas the day of your exam. Depending on the specific ultrasound, you may be asked to not eat or drink anything after midnight prior to your exam. If you are diabetic, you may also be asked to not take your insulin or pills the morning of. If you have any doubts, please confirm with your technician what they need you to do so we can properly screen you!
