Abnormalities in body temperature (that is, fever and hypothermia) are common (14). Such abnormalities are components of diagnostic criteria for certain disorders (58), influence clinical management decisions (9, 10), and are associated with increased mortality in certain patient populations (11, 12). For most adult and pediatric populations, fever is defined as a body temperature of 38.0C or higher (1315); this definition can vary according to certain patient characteristics (for example… 
Assessment and Evaluation of Body Temperature
Although today there is a general acceptance of body temperature as a range rather than a fixed temperature, the 1871 definitions of normal body temperature and fever still are considered the world-wide norm.
Ear measurement of temperature is only useful for screening for fever in an adult emergency department
The examined ear thermometer is able to detect fever, defined as ≥38 oC rectally in an adult ED population by using an ear cut-point of 37.5 oC, but not to measure the exact temperature.
Accuracy of zero-heat-flux thermometry and bladder temperature measurement in critically ill patients
The results for zero-heat-flux and bladder temperatures were virtually identical within about a tenth of a degree, although TZHF tended to underestimate TBlood, therefore either is suitable for clinical use.
Temporal artery temperature measurements versus bladder temperature in critically ill patients, a prospective observational study
The TAT is not sufficient for clinical practice in critically ill adults, and subgroup analysis showed that when patients were receiving intravenous norepinephrine, the measurements of the test method deviated more from the reference method.
Investigation of Non-invasive Continuous Body Temperature Measurements in a Clinical Setting Using an Adhesive Axillary Thermometer (SteadyTemp®)
An adhesive axillary thermometer (SteadyTemp®) which allows continuous non-invasive temperature measurements is validated and information of the new diagnostic possibilities when using this wearable device and where it could be beneficial is provided.
Performance of axillary and rectal temperature measurement in private pediatric practice
Axillary temperatures are always lower than rectal ones, the limits of agreement are quite wide and axillary thermometers have a good sensitivity but limited specificity and are therefore adequate for fever screening.
A comparison of temporal artery thermometers with internal blood monitors to measure body temperature during hemodialysis
Using the dialysis machine to monitor body temperature may result in more accurate readings and is likely to reduce the purchasing and maintenance costs associated with manual temperature readings, as well as easing the workload for dialysis staff.
Comparison of rectal and tympanic membrane temperature in healthy exercising dogs
The aim of the study was to determine if TMT diverged from RT following exercise in healthy dogs, and if the same divergence occurs in dogs, TMT may not be suitable for use when monitoring the temperature of canine athletes.
Common body temperature sites provide invalid measures of body core temperature in hyperthermic humans wearing American football uniforms
TAXL, TFHD, TEAR, and TORL should not be used to diagnose or monitor American football players with EHS.


Insufficiency in a New Temporal-Artery Thermometer for Adult and Pediatric Patients
The hypothesis that the SensorTouch™ is sufficiently precise and accurate for routine clinical use is tested by studying adults and children who developed mild fever, a core temperature of at least 37.8°C, after cardiopulmonary bypass.
Accuracy of Infrared Ear Thermometry in Children
The mean difference was large and the 95% limits of agreement was wide, and the accuracy of infrared ear thermometers in children is poor, and it cannot replace rectal thermometry in clinical practice of children.
Is axillary temperature an appropriate surrogate for core temperature?
Axillary temperature appears to be an acceptable alternative to rectal/oral temperature measurements in children, and should be used as a surrogate for oral/rectal temperatures in children aged 6–14 years.
A comparison of five methods of temperature measurement in febrile intensive care patients.
BACKGROUND A clinically useful temperature measurement method should correlate well with the body's core temperature. Although previous investigators have studied temperature readings from different

The chemical thermometer was more accurate, reliable and associated with fewer clinically significant temperature differences compared with the tympanic thermometer, however,Compared with the pulmonary artery catheter both methods were associated with erroneous readings.

Oral and temporal artery measurements were most accurate and precise and axillary measurements underestimated pulmonary artery temperature; diaphoresis and airflow across the face may affect temporal arteries measurements.
Accuracy of tympanic and infrared skin thermometers in children
This study demonstrated that the tympanic, Beurer and Thermofocus thermometers cannot reliably predict rectal temperature and therefore the authors do not advise replacement of rectal measurement as the gold standard for detecting fever in children by one of these devices.
Estimating core temperature in infants and children after cardiac surgery: a comparison of six methods.
BACKGROUND Monitoring temperature in critically ill children is an important component of care, yet the accuracy of methods is often questioned. Temperature measured in the pulmonary artery is
