METHOD FOR DETERMINING PROFESSIONAL FITNESS OF A PERSON TO WORK UNDER CONDITION OF FOAM POLYURETHANE PRODUCTION BASED ON ISOCYANATES Russian patent published in 1997 - IPC

FIELD: medicine. SUBSTANCE: method involves performing blood examination in vitro including one determining leukocyte base activity with respect to phagocytosis in buffer solution of nitro blue tetrazolium and determining sensibilized leukocytes activity in buffer solution of nitro blue tetrazolium of the same type, but with added allergen solved in petroleum ether in the 1: 60 proportion. The so produced solution is solved in distilled water in the 1: 33 proportion. Functional activity coefficients K₁ and и K₂ are calculated to consider professional fitness to be the case when K₁ ≅ 0.15 and K₂-K₁ ≥ 0.01. If K₁ ≥ 0.22 and K₁-K₂ 0.01, professional fitness is considered not to be the case. EFFECT: enhanced accuracy of the method.
