Measured values and frequency of measurement

The following table will help you to interpret the measured body temperature:

normal temperature 36,3 °C – 37,4 °C
sub-febrile temperature 37,5 °C – 38,0 °C
slight fever 38,1 °C – 38,5 °C
moderate fever 38,6 °C – 39,0 °C
high fever 39,1 °C – 39,9 °C
very high fever 40 °C and over

It is important that the measurement location, the time of day and the thermometer are kept constant, so that the individual measurements are all taken under the same conditions.

The body temperature of each individual is different and can increase by up to 1.3 °C during the course of the day.

Practice has shown, however, that the most meaningful temperature values for determining fever are obtained between 7 and 8 p.m.

In most cases, body temperature trends are more significant than individual measurements. Temperature curves with measured values taken in close sequence can best be compared by a doctor and these, together with other clinical observations, can help provide secure diagnoses. Mobile temperature monitors are an especially suitable means of obtaining temperature curves and recognising trends in the development of body temperature. These temperature monitors measure the body temperature continuously at set intervals and store the values measured.
