Cutaneous thermic changes induced by a skin prick test reaction were measured by an infrared thermography camera (computerized dynamic telethermography, CDTT). Changes in skin temperature (T degree) detected by CDTT were compared with the mean diameter of allergen-induced skin reactions. Cutaneous thermic increase detected by CDTT correlated well with the mean wheal diameter measured in millimeters (r = 0.938, p < 0.001). Average coefficient of variation for repeated CDTT measurements was 4.6%. CDTT provides a reproducible and precise method for measuring allergen-induced skin reactions. Moreover, the continuous recording of the skin temperature represents an additional parameter for the quantification of wheal reactions.
通过红外热成像相机（计算机化动态远距热成像，CDTT）测量皮肤点刺试验反应引起的皮肤温度变化。将CDTT检测到的皮肤温度（T度）变化与变应原诱导的皮肤反应的平均直径进行比较。CDTT检测到的皮肤温度升高与以毫米为单位测量的平均风团直径密切相关（r = 0.938，p < 0.001）。重复进行CDTT测量的平均变异系数为4.6%。CDTT为测量变应原诱导的皮肤反应提供了一种可重复且精确的方法。此外，皮肤温度的连续记录是定量风团反应的一个额外参数。
