The mid infrared wavelengths include fundamental vibration signatures of major molecules that compose the tissues and biological fluids. Therefore, the mid infrared light absorption spectrum of a biologic fluid is representative of its composition, as it accurately reflects the structure of the molecules constituting the sample. It provides a comprehensive metabolic profile.

It is then possible to classify the spectrum of measured samples relatively to healthy cases and pathological cases references. Infrared spectrum diagnosis score is based upon analysis of the entire molecular characteristics of the sample, and not based on the analysis of a small number of a priori identified markers.

DIAFIR is a compelling technology for recording and analyzing mid-infrared light patient blood serum signature, in order to provide diagnosis score within minutes.



DIAFIR has developed the SPID™ platform, combining:

  • patented mid-infrared light biosensor.
  • dedicated spectroscopic device.
  • proprietary machine learning algorithm allowing diagnosis score delivery within minutes.
