Body temperature
Normal body temperature is a range. The following table shows that ranges of normal
also vary by site. Therefore, readings from different sites, even if taken at the same time,
should not be directly com-pared.
A person's normal temperature range tends to decrease with age.
The following table shows normal ThermoScan ranges by age.
Normal ThermoScan temperature ranges
The range of normal varies from person to person and can be influenced
by many factors such as time of day, level of activity, medications and
gender.
