In vivo diagnosis with purified tropomyosin in mite and shellfish allergic patients

The prevalence of tropomyosin was low in mite-sensitized patients (2.7 %) and high in shellfish allergic patients (28.6%). The higher prevalence of tropomyosin was found in patients sensitized to both mite and shellfish (38.5%). The selection of tropomyosin-sensitized patients by SPT might help in the choice of appropriate treatments or management for these patients.
