FIELD: medicine. SUBSTANCE: method involves measuring cobalt contents in blood plasma, copper and iron contents in erythrocytes, zinc, copper and iron contents in lymphocytes, sodium contents in exhaled air condensate, sodium, potassium, magnesium, calcium, zinc, copper and iron in hair. Differential diagnosis coefficient is calculated from formula DDC= -12.2 x Co(p1)-3.60 x Cu(er) +0.014 +Fe(er)+0.0034 x Zn(ly) -.0.017 x Cu(ly) -0.0077 x Fe(ly)-0.018 x Na(cond) -0.022 x Na(v)-0.0040 x K(v) - 0.0101 x Mg(v) - 0.0042 x Ca(v) + 0.00525 x Zn(v) + 0.464 x Cu(v) + 0.0493 x Fe(v), where Co(p1) is the cobalt concentration in plasma in mcmole/l, Cu(er) is the copper concentration in erythrocytes in g/cell, Fe(er) is the iron concentration in erythrocytes in g/cell, Zn(ly) is the zinc concentration in lymphocytes in g/cell, Cu(ly) is the copper concentration in lymphocytes in g/cell, Fe(ly) is the iron concentration in lymphocytes in g/cell, Na(cond) is the sodium concentration in exhaled air condensate in mcmole/l, Na(v) is the sodium concentration in hair in mcg/g, K(v) is the potassium concentration in hair in mcg/g, Mg(v) is the magnesium concentration in hair in mcg/g, Ca(v) is the calcium concentration in hair in mcg/g, Zn(v) is the zinc concentration in hair in mcg/g, Cu(v) is the copper concentration in hair in mcg/g, Fe(v) is the iron concentration in hair in mcg/g. The DDC value being greater than 2.00, infection-dependent bronchial asthma diagnosis is to be set. The value being less than or equal to 2.00, atopic bronchial asthma diagnosis is to be set. EFFECT: high accuracy of diagnosis. 1 tbl
