DIAGNOSTIC TECHNIQUE FOR BRONCHIAL ASTHMA Russian patent published in 2009 - IPC G01N33/52 

FIELD: medicine.

SUBSTANCE: method consists in estimate of allergic status by infrared spectroscopy of serum sample of venous blood. The blood sample is dried up, powdered to prepare suspension in liquid petrolatum with infrared spectroscopy within 1200-1000 cm^-1 to determine peak heights of absorption band at maxima 1170 cm^-1, 1165 cm^-1, 1160 cm^-1, 1150 cm^-1 and 1140 cm^-1. The coefficients x, y and z are calculated at rotation of axis x by 29°, axis y by 55° and axis z by -1°. The obtained three-dimensional distribution is projected on frontal plane to receive two-dimensional coordinates as diagnostic polygons, and the values (x, y) -0.8431; 1.2793 // -0.1328; 0.7552 // 0.1017; 0.3493 // 0.0397; 0.1414 // -0.9259; 0.8172 allows diagnosing bronchial norm.

EFFECT: higher accuracy and diagnostic objectivity by eliminating subjective interpretation of disease signs.
