Venom Bumble Bee (Bombus terrestrus) IgG

Test Code: 91820
Expand All Collapse All
Clinical Utility

The clinical correlates for bumble bee venom IgG responses have not been established and there is no published protective threshold. However, by analogy to other venoms that have been studied, it is expected that increasing concentrations of bumble bee specific IgG will correlate with protection.

Procedure

Enzyme immunoassay (FEIA). A standard curve is used to calculate the specific IgG concentrations. The calibrators are referenced to the International Reference Preparation for serum immunoglobulins. This test has not been cleared or approved for diagnostic use by the U.S. Food and Drug Administration.
