4.Note on Body Temperature
Normal body temperature is a range. It
varies from person to person and can
fluctuate throughout the day.
Body temperature also varies by sites.
Therefore, the iF100B Forehead
Thermometer should not be used to obtain
body temperature from other parts of the
body.
To determine if an individual is experiencing
an elevated body temperature or has a fever,
it is therefore critical to know, as a reference
point, the individual’s normal body
temperature range when he/she is well.
Normal body temperature fluctuates
throughout the day and is affected
by external factors. The body
temperature of an individual is the
lowest between 2:00 a.m. and 4:00
a.m. and the highest between 2:00
p.m. and 8:00 p.m. An individual's
body temperature typically changes
by less than 1°C (1.8 °F) each day.
