Fourier Transform Infrared Spectroscopy (FTIR) used for biomedical diagnosis of human saliva sample. Saliva is taken for experimental analysis from a normal person and also from a Gastric problem related patient. The spectral bio-diagnosis of normal human saliva sample shows the following vibrational functional groups O-H at 3305 cm-1, C-H from 2928 to 2856 cm-1, C=N and C=C obtained at 1658 cm-1, C-H bend at 1455 cm-1, C=S and C-C from 1159 to 1064 cm-1, C-H out of plane bend at 748 cm-1 and 483 cm-1 assigned for C-H deformation.
