A rapid diagnosis method for organ specific disease state and an apparatus for carrying out the inventive method are based on obtaining an infrared absorbance spectra of a patient's blood at a frequency range from about 400 cm<-1-1 >to about 4000 cm.<-1>. Comparing it with the predetermined normal infrared absorbance spectra of known healthy subjects for the presence or absence of predetermined features such as increase or decrease of infrared absorbance, peaks at particular frequencies allows for accurate diagnosis of a disease of an organ, including most major organs such as a heart, lungs, stomach, liver, kidneys, brain, etc.
