Ampicillin/Ampicilloyl IgE, Allergen

Included Tests

Ampicillin IgE, Allergen; Ampicilloyl IgE, Allergen

Clinical Significance

 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

ImmunoCAP® Quantitative Scoring Guide:

Class	IgE (kU/L)	Comment
0	<0.10	Negative
0/1	0.10-0.34	Equivocal/Borderline
1	0.35-0.69	Low Positive
2	0.70-3.49	Moderate Positive
3	3.50-17.49	High Positive
4	17.50-49.99	Very High Positive
5	50.00-99.99	Very High Positive
6	>99.99	Very High Positive

Note that Eurofins includes an extra calibrator at 0.10 kU/L and uses it to
define an optional equivocal class

Methodology:

• Immunocap (Eurofins)

Clinical Significance

 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

Documentation

 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. 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
