Allergen, Tree, Japanese Cedar Tree
Also known as: J CEDAR
Use
This test aids in the identification of allergic responses to Japanese Cedar Tree allergens by measuring allergen-specific IgE levels. These results can help diagnose allergic conditions such as hay fever caused by exposure to Japanese Cedar Tree pollen. Increasing ranges of allergen-specific IgE concentrations may reflect higher sensitization towards the allergen but might not always correlate precisely with the severity of clinical reactions or results from skin testing.
Special Instructions
Not provided.
Limitations
Results of specific IgE concentrations between 0.10-0.34 kU/L are indeterminate in clinical relevance and intended for specialist interpretation. The degree of allergen-specific IgE in the serum does not always correlate with the intensity of clinical responses or in-vitro reactivity. A negative result does not definitively exclude the possibility of an allergy or anaphylaxis.
