“…LDF is a valuable, noninvasive method of analyzing microcirculatory changes in RP [18–22, 28]. It measures the flux of blood cells in a designated area, making it well suited to monitor transient alterations in skin circulation, as well as determine general perfusion [29–32].…”

The aim of this study was to measure the sensitivity and specificity of transcutaneous oxygen tension and postocclusive hyperemia testing using laser Doppler flowmetry in patients with primary Raynaud's phenomenon. One hundred patients and one hundred controls were included in the study. Baseline microvascular blood flow and then time to peak flow following occlusion were measured using laser Doppler flowmetry. Afterwards, the transcutaneous oxygen tension was recorded. The sensitivities of baseline microvascular blood flow, postocclusive time to peak flow, and transcutaneous oxygen tension were 79%, 79%, and 77%, respectively. The postocclusive time peak flow had a superior specificity of 90% and area under the curve of 0.92 as compared to 66% and 0.80 for baseline microvascular flow and 64% and 0.76 for transcutaneous oxygen tension. Time to postocclusive peak blood flow measured by laser Doppler flowmetry is a highly accurate test for differentiating patients with primary Raynaud's phenomenon from healthy controls.

“…Among objective RP severity measurements, fingertip rewarming in response to local cold challenge has been explored using various types of technology platforms such as surface temperature measurement [4,5], plethysmographic measurement of acral blood flow [6,7], capillary flow upon cold challenge [8,9], or laser Doppler measurement [4,10] (reviewed in [11]). Recently, we reported a tabletop device designed to record fingertip rewarming upon cold challenge based on detection of skin surface infrared irradiation [12].…”
