Before Use: About Normal Body Temperature &
Fever
Forehead and temple area temperature differs from internal temperature, which can be taken orally or
rectally.
Vasoconstriction, an effect which constricts the blood vessels and cools the skin, can occur during the
early stages of a fever.
In this case, the temperature measured by the Infrared thermometer may be unusually low. If the
measurement therefore does not match the patient's own perception or is unusually low, repeat the
measurement every 15 minutes. As a reference, you can also measure the internal body temperature
using a conventional oral or rectal thermometer.
Body temperature can vary from one individual/person to next.
An individual's temperature will also vary depending on location and time of day. The table below shows
the statistical normal ranges from different sites.
Please keep in mind that temperatures measured from different sites, even at the same time, should
not be directly compared. Fever indicates that the body temperature is higher than normal. This
symptom may be caused by infection, overdressing or immunisation. Some people may not experience
fever even when they are ill.
These include, but are not limited to, infants younger than 3 months old, individuals with compromised
immune systems, individuals taking antibiotics, steroids, or antipyretics (aspirin, ibuprofen,
acetaminophen), or individuals with certain chronic illnesses. Please consult your physician when you
feel ill even if you do not have fever.
