Tryptase, study 2

Two investigations conducted by Garvey et al. (2010a,b) involved a total
of 438 patients undergoing surgery of various kinds. The main
objective was to study the level of serum tryptase and changes
occurring in this during surgery, in particular in connection with an
allergic reaction.


Study 2:

This study is concerned with 318 patients with a suspected allergic
reaction during anesthesia. For these patients, a blood sample for
serum tryptase is measured 1-4 hours after the reaction and a baseline
level is taken after more than 24 hours when the suspected allergic
reaction has disappeared. For these patients, we have additional
information regarding the severity of the reaction and information on
the result of subsequent allergy testing.

           that is a constant threat to life.
        5: A moribund patient who is not expected to survive 
           without the operation.
        6: A declared brain-dead patient whose organs are 
           being removed for donor purposes.
