The rate of release in vitro of four potassium dichromate concentrations (0.5, 0.1, 0.05 and 0.01%) was determined. In the course of 24 h, 90.1-97.5% was released of the total K2Cr2O7 amount in 48 h. Out of 30 patients positive to 0.05% dichromate when the patch test was done routinely, 29 were also positive when the patch was removed after 24 h. The effect of the earlier removal of the patch test was also noted in seven other patients, when results of tests with lower dichromate concentrations were taken into account.
测定了四种重铬酸钾浓度（0.5%、0.1%、0.05%和0.01%）的体外释放率。在24小时内，48小时总K2Cr2O7量的90.1 - 97.5%被释放。在常规进行斑贴试验时对0.05%重铬酸盐呈阳性的30名患者中，24小时后移除斑贴时，29名患者仍呈阳性。当考虑较低重铬酸盐浓度的试验结果时，在其他7名患者中也注意到了提前移除斑贴试验的影响。
