The TROMBOTSITOPENYCHESKY TEST
(a thrombocyte [y\-f Greek penia poverty; a synonym thrombocytopenic test) — the diagnostic method of allergic diseases consisting in calculation of thrombocytes of blood before impact on an organism of allergen.
It is offered Blinds, Uanye and Kol-lerom (H. Storck, R. Hoigne, F. Roller) in 1952 on the I International congress of allergists in Zurich. T. t. it is similar to the leykotsitopenichesky test (see); it is based that after influence of allergen the maintenance of thrombocytes in blood decreases in comparison with initial quantity. Calculation of thrombocytes is made in the morning on an empty stomach twice (at an interval of 30 min.) before influence of allergen, and then directly after its influence in 30, 60 and 90 min. Thrombocytes count according to the practical standard (I eat. Gemogramma). According to M. M. Chakhoyan-Brutyan (1970), the test is considered positive if the number of thrombocytes decreases by 25% and more.
T. t. apply to diagnosis of hl. obr. medicinal and food allergy (see Jiekarstvennaya an allergy, Food allergy). Diagnostic value has only a positive take. T. t. is only additional diagnostic reception and it shall be combined with other diagnostic methods of an allergy.
