Noncontact forehead temperature measurement by handheld infrared thermometer was used as a screening tool for fever. However, the accuracy data and normal range of forehead temperature determined by this method were not available.
The temperature readings from 3 handheld infrared thermometers were validated against an electronic thermometer. Normal range of forehead temperature was determined by measuring the forehead temperature in 1000 apparently healthy subjects.
Significant differences were detected in readings obtained by the 3 different handheld infrared thermometers (analysis of covariance, P < .001) The most accurate one was chosen, and the normal range of forehead temperature in 1000 subjects detected by this method was 31.0 degrees C to 35.6 degrees C.
Our study shows that commercially available, handheld infrared thermometers require individual validation. Forehead temperature in excess of 35.6 degrees C is suggestive of fever. Further studies are required to confirm accuracy of this value in detecting fever.
使用手持式红外温度计进行非接触式额头体温测量作为发热的筛查工具。然而,通过这种方法确定的额头体温的准确性数据和正常范围尚无可用信息。
将3款手持式红外温度计的温度读数与电子温度计进行验证。通过测量1000名明显健康受试者的额头体温来确定额头体温的正常范围。
在3种不同的手持式红外温度计获得的读数中检测到显著差异(协方差分析,P < .001)。选择了最准确的一款,通过该方法检测的1000名受试者的额头体温正常范围为31.0摄氏度至35.6摄氏度。
我们的研究表明,市售的手持式红外温度计需要进行个体验证。额头体温超过35.6摄氏度提示发热。需要进一步研究来确认该值在检测发热方面的准确性。
