Cellulitis Thermoindicator Kit (Cellu-test). 
What it is and how it works.

The Kit Cellulitis Thermoindicator (Cellu-Test) is a sheet of microencapsulated liquid crystal that through simple contact with the skin indicates whether cellulitis exists or not, and if so, shows the degree of said cellulitis. One of the first external symptoms of cellulitis is the difference of the temperature of the skin in the region affected by cellulitis. The human body has to maintain a stable temperature and does this by means of a thermoregulation mechanism increasing or decreasing the flow of blood close to the surface of the skin. This makes the temperature rise or fall.

Deficient or abnormal blood circulation produces a cooling of the zone of the skin affected by cellulitis. Only in very advanced phases of cellulitis is it possible to detect the difference in cutaneous temperature by touching the region to be examined. Without doubt, from the start of cellulitis there are almost imperceptible differences in the temperature of the skin.  This requirement of measuring practically imperceptible differences can be met by a new method: "Thermography with microencapsulated liquid crystals."
