International ME/CFS and FM Awareness Day Is On May 12, 2018
Thomas Hennessy, Jr., selected May 12th to be our international awareness day back in 1992. He knew that May 12th had also been the birthday of Florence Nightingale. She was the English army nurse who helped to found the Red Cross as well as the first school of nursing in the world.

    Testing for EDS - related POTS

    The Mayo laboratory utilizes two test batteries, the autonomic reflex screen (ARS) and the reflex sympathetic dystrophy (RSD) screen. The former comprises the quantitative sudomotor axon reflex test (QSART), orthostatic blood pressure (BP) and heart rate (HR) responses to tilt, HR response to deep breathing, the Valsalva ratio, and beat-to-beat BP responses to the Valsalva maneuver, tilt, and deep breathing. The RSD screen comprises the recording of skin temperature, resting sweat output, and QSART distributions bilaterally.

    Quantitative Sensory Testing (QST) is a valuable method for diagnosing peripheral nervous system disorders, including chronic pain and pain related to various diseases, such as Diabetes and CRPS. QST essentially determines the sensation and pain thresholds for cold and warm temperatures, and the vibration sensation threshold by stimulating the skin and comparing the results to normative values built in the software. When the stimulus activates stimuli-specific receptors; the nerve fibers that innervate the receptors communicate the stimuli's message to the central nervous system, where feeling occurs.

    If you "Google around," I think you'll find that these are tests of the autonomic nervous system rather than specifically for POTS or EDS.
