Doctors recommend rectal measurement for newborn infants
within the first 6 months, as all other measuring methods might
lead to ambiguous results. If using a non contact thermometer
on those infants, we always recommend verifying the readings
with a rectal measurement.
In the following situations it is recommended that three temper-
atures are taken with the highest one taken as the reading:
1. Children under three years of age with a compromised
immune system and for whom the presence or absence of
fever is critical.
2. When the user is learning how to use the thermometer for
the first time until he/she has familiarized himself/herself with
the device and obtains consistent readings.
3. If the measurement is surprisingly low.
Readings from different measuring sites should not be
compared as the normal body temperature varies by
measuring site and time of day
, being highest in the evening
and lowest about one hour before waking up.
Normal body temperature ranges:
- Axillar: 34.7 - 37.3 °C / 94.5 - 99.1 °F
- Oral: 35.5 - 37.5 °C / 95.9 - 99.5 °F
- Rectal: 36.6 - 38.0 °C / 97.9 - 100.4 °F
- Microlife NC 150: 35.4 - 37.4 °C / 95.7 - 99.3 °F
