What temperature measurement method is most reliable for mass screening?
As corporate America is anxious to open or keep open their doors to employees and visitors, company leaders are scrambling to find ways to determine if someone is at risk for COVID-19 or other illness that can spread to others. The intention is to keep everyone safe.
Temperature scanning systems, like infrared cameras are favored for these valued reasons:
- The non-contact feature keeps the operator at a safe distance
- Screening is quick, making it possible to screen many people in a short time, without significant entry delay
The ultimate challenge for effective screening is temperature accuracy. Not of the camera itself, but of the relationship between the camera, the person and the surrounding environment.
As exact as it may seem on the surface, relying only on the skin measurement will not provide the results required to protect the individual or business.
The human calibration method is the most reliable method of temperature assessment.
Infrared Thermal Imaging utilizes a specific software algorithm to:
- Calibrate temperatures of 5-10 healthy individuals (without elevated temperature) creating an average, human calibrated range, in the exact same environment.
- Everyone is then compared to this human control group.
- General expectation is that an alarm notifies the operator if a person registers 2⁰F higher than the control group. Software allows for this tolerance level to be adjusted as needed. This considers variants for skin temperature fluctuations.
Even this improved “human calibration” method of screening is subject to variables. The International Organization for Standards (ISO) and the FDA recommend secondary screening of those flagged by the thermal screening device. This would be with a method that measures core temperature such as a basal thermometer, or preferably a tympanic ear thermometer with disposable sleeves. An elevated core temperature suggests a person is not well, but it does not specifically suggest that they have a pandemic disease.
Temperature controls our quality of life and the measurement of different types of temperatures are inter-related, especially when utilizing infrared thermal imaging for human temperature screening.
But human temperature can be complicated. In this article, we explain the different areas of temperatures on a body and how they are measured.
Thermography is a science. Over 90% of the universe has been mapped with the use of infrared technology. It is one of the most useful tools for scanning the earth, as temperature is a primary consideration in the survival of Planet Earth. You will see that it is also a primary consideration in the maximum survival time of the individual human being and for humanity as a whole. With the realization of the role that inflammation plays in the overall health of the human being, we can no longer deny the value of infrared technology for the assessment of human health and the catalyst for the reality of prevention as a treatment strategy.
