Normal Axillary Temperature Ranges by Age Group Normal axillary temperatures vary by age:
Infants (0-3 years old): 36.2–37.5℃
Children (4-12 years old): 36.0–37.3℃
Adults (13-64 years old): 36.0–37.2℃
Elderly (65+ years old): 35.8–37.0℃ (slightly lower range)
Steps to Accurately Read a Mercury-Free Glass Thermometer Start with pre-measurement prep:
Shake the thermometer downward to reset the liquid column to below 35℃. Clean the bulb end thoroughly with alcohol to avoid contamination.
During use, place the bulb end tightly under the armpit, ensuring it's in full contact with skin. Clamp firmly and keep still for 5-10 minutes to allow accurate temperature absorption.
When reading, hold the thermometer horizontally at eye level. Locate the thin liquid column and read the temperature at its highest point. A temperature 0.5℃ or more above the age-specific normal range is considered a fever.
