大多数实验室测试结果的显示都包括一个标准参考范围。然而，对于一些患者(例如，患有慢性病的患者)，在标准范围内获得结果可能是无法实现的、不合适的，甚至是有害的。我们研究的目的是测试在实验室检测结果的视觉显示中包括标准范围之外的临床合适的目标范围的影响。来自人口统计学不同的基于网络的小组的参与者(N=6776)将假设的糖化血红蛋白(HbA1c)测试结果(HbA1c 6.2%或8.2%)视为2型糖尿病治疗方案的一部分。测试结果视觉显示包括仅标准范围(4.5%-5.7%)、添加到标准范围的目标范围(6.5%-7.5%)或仅目标范围。结果以以下三种显示格式中的一种显示：(1)表格；(2)简单的双色数字线(简单线)；或(3)用彩色方块表示诊断类别的数字线(方块线)。主要的结果衡量标准是对测试结果的理解和负面反应。当目标范围信息不影响对HbA1c=8.2%结果的理解时，与无目标范围和目标范围添加条件相比，只显示目标范围会产生更高的理解水平，并减少对HbA1c=6.2%测试结果的负面反应。与其他格式相比，球门距离信息在拦截线条件下的帮助较小。用临床上合适的目标范围取代标准范围可以帮助患者更好地理解他们的测试结果与他们的个人目标之间的关系。
Most displays of laboratory test results include a standard reference range. For some patients (eg, those with chronic conditions), however, getting a result within the standard range may be unachievable, inappropriate, or even harmful. The objective of our study was to test the impact of including clinically appropriate goal ranges outside the standard range in the visual displays of laboratory test results. Participants (N=6776) from a demographically diverse Web-based panel viewed hypothetical glycated hemoglobin (HbA1c) test results (HbA1c either 6.2% or 8.2%) as part of a type 2 diabetes management scenario. Test result visual displays included either a standard range (4.5%-5.7%) only, a goal range (6.5%-7.5%) added to the standard range, or the goal range only. The results were displayed in 1 of the following 3 display formats: (1) a table; (2) a simple, two-colored number line (simple line); or (3) a number line with diagnostic categories indicated via colored blocks (block line). Primary outcome measures were comprehension of and negative reactions to test results. While goal range information did not influence the understanding of HbA1c=8.2% results, the goal range only display produced higher levels of comprehension and decreased negative reactions to HbA1c=6.2% test results compared with the no goal range and goal range added conditions. Goal range information was less helpful in the block line condition versus the other formats. Replacing the standard range with a clinically appropriate goal range could help patients better understand how their test results relate to their personal targets.
