Test Code LATEX Latex (Hevea braziliensis) IgE (Serum)
Clinical Indications
This assay is used to detect allergen specific-IgE using the
ImmunoCAP® FEIA method. In vitro
allergy testing is the primary
testing mode for allergy diagnosis.

to
define an optional equivocal class.
Critical Value

Interpretation
The ImmunoCAP FEIA method uses as the
solid phase a flexible,
hydrophobic cellulosic polymer to which allergen has been
covalently linked. The advantage of this system is that it has
a
very high antigen binding capacity when compared to other
systems
and it has minimal non-specific binding with high total IgE.
Viracor Eurofins provides an optional low range calibrator at
0.1
kU/L and a 0/1 class. This test has been cleared or approved
for
diagnostic use by the U.S. Food and Drug Administration.
