HomeAgain Thermochip and Thermochip Mini: More than just identification

 

Intelligent identification for temperature monitoring.

HomeAgain® Thermochip® and Thermochip® Mini are a new generation of identification microchips, which incorporate patented and integrated temperature biosensors alongside the tiny passive radio-frequency identification device (RFID), which operates as any other identification microchip.

This enables the pet's subcutaneous temperature and identification number to be read simultaneously, using a compatible reader such as SureSense™ Universal Microchip Reader or Global Pocket Reader® Plus (GPR+).

What are the clinical applications for utilising a Thermochip?

The location of the microchip makes it much easier, and far less stressful for the animal, to take multiple temperature measurements, enabling subcutaneous temperature to be monitored frequently over time.

What do we know about temperature variability?

Although veterinary professionals use single rectal thermometry as the gold standard1, it is worth noting that rectal temperatures are variable, if taken frequently enough!2

Normal body temperature sits within a range, which varies from one pet to another, and can be influenced by factors such as:

The animal's physiological temperature interval depends on its own intrinsic factors and may also vary in healthy animals. 

Therefore temperature trends are more useful than one-off readings. Equally readings from different temperature sites cannot be compared.

  • Is Thermochip a reliable method of measuring temperature?

    Thermochip collects very similar temperature values to those measured by the 3 digital thermometers commonly used in veterinary practice, when they are placed under the same temperature-controlled conditions.

    Independent laboratory study11:

    Temperatures collected by Thermochip (10 microchips) versus 3 digital thermometers, under the same temperature-controlled conditions, at 0.5°C intervals, between 33°C and 43°C:

A veterinary physiologist8 collected and reviewed multiple temperature studies concluded:

Axillary, auricular or any other temperature readings should not be interpreted interchangeably with the ordinary rectal temperature range.

Instead, it would be better to compare them with a reference range for the particular site.

This absence of correlation is already well known in human medicine9 and was also seen for dogs10.

 

Benefits of HomeAgain Thermochip and Thermochip Mini include:

  • Better understanding of an individual animal's temperature range.
  • Enhanced animal welfare through reducing the stress of obtaining a temperature reading.
  • Utilising innovation which strenghtens the clinic image.
  • Easier in-clinic patient management.
  • Saves time for vet and clinic staff.
  • Compatability with the Sure Petcare range of products, including microchip-enabled pet flaps, feeders and drinking stations.

 

HomeAgain Thermochips are available to order through your Direct by MSD distribution partner.
