General information, not an individual diagnosis. Ask a healthcare professional if you are unsure about your situation.
A displayed temperature cannot be interpreted independently of how it was measured. The thermometer and measurement site influence the result. Check the device instructions rather than borrowing a method from a different model.
Ameli recommends measuring away from physical exertion, with normal covering and outside a very hot environment. These conditions help avoid some disturbances; they do not replace the thermometer's own instructions.
To make your record clear, note the displayed value, unit, time, device and measurement site. This small record is a practical aid to discussion, not a diagnostic instruction issued by Ameli.
An oral reading can be affected by recent food or drink and breathing with the mouth open. An ear reading depends on positioning and probe cleanliness; Ameli advises against this method before age two.
Infrared forehead devices can be very inaccurate, depending on air, hair or sweat. If two readings surprise you, describe their conditions to the professional rather than automatically applying a supposedly universal correction.
Also explain the person's age and the symptoms that concern you. A record helps describe the circumstances; it cannot, on its own, determine a medicine or rule out the need for care.
