Which is more accurate: axillary temperature or oral temperature?
Axillary and oral temperatures are generally both quite accurate when measured correctly, making them difficult to compare directly.
1. Axillary Temperature
Human body temperature is usually not a specific value but rather falls within a certain range. In clinical practice, body temperature typically refers to average body temperature, such as axillary (underarm), rectal, or oral temperature. Axillary temperature refers to the measurement taken under the arm by placing a thermometer in the armpit. Normally, axillary temperature ranges between 36–37°C. If measured properly—for example, by ensuring the thermometer is held snugly against the skin and left in place for about 5–10 minutes—the result is usually accurate.
2. Oral Temperature
Oral temperature refers to the temperature measured inside the mouth. Under normal conditions, oral temperature ranges from 36.3–37.2°C. For accurate measurement, the patient should place the tip of the thermometer beneath one side of the tongue and press it firmly with the tongue, maintaining this position for approximately 5–10 minutes until the reading stabilizes, which typically yields an accurate result.
