Evaluation of tryptase measurement in diagnosing allergic diseases / 中华检验医学杂志

ABSTRACT

Objective To evaluate the use of tryptase in diagnosing allergic diseases.Methods Serum tryptase was measured by Unicap 100 in 35 patients with different types and states of allergic diseases, and 30 healthy volunteers as controls ;Serum tryptases were compared with IgE level.Results Among the 35 allergic patients, 18 cases were with chronic urticaria(4.74?2.54)?g/L; 10 cases had past histories of anaphylaxis shocks(4.86?2.55)?g/L ;7 cases were in acute phase of anaphylaxis(17.4?7.87)?g/L ;30 healthy volunteers(4.36?1.67)?g/L. A statistically significant increase in tryptase concentration was found in patients with acute phase of anaphylaxis compared with other groups.No correlation was found between tryptase concentration and total IgE level.Conclusions Measurement of Serum tryptase level could be an additional tool for diagnosis of anaphylaxis but not chronic urticaria.
