METHOD FOR DETERMINING DEGREE OF SEVERITY OF CHRONIC OBSTRUCTIVE PULMONARY DISEASE Russian patent published in 2014 - IPC G01N33/74 

FIELD: medicine.

SUBSTANCE: blood is examined. The steroid hormones cortisol (nmole/l) and DHEA-S (mcmole/l), as well as the oxidative stress values - oxidative modified proteins (OMP, nM/mg, protein), malondialdehyde (MDA, nM/ml) and SH groups mg% are evaluated. The forced expiratory volume 1(%) FEV1 is calculated by formula on the basis of the derived values. If the derived FEV1 is within 50% to 80%, the presence of a moderate degree of chronic obstructive pulmonary disease; the FEV1 being within the range of 30 to 49% means a severe degree of chronic obstructive pulmonary disease (COPD), and the derived value being less than 30% shows an extremely severe degree of COPD.

EFFECT: reliable determination of a degree of severity of chronic obstructive pulmonary disease.
