Specific IgE - Alternaria alternata (Mold)
- Sample Type
- Standard
- Fasting
- No
- Unit
- kUA/L
This test measures the concentration of allergen-specific Immunoglobulin E (IgE) antibodies in the serum directed against Alternaria alternata, one of the most common outdoor molds associated with asthma and allergic rhinitis. Alternaria spores are highly allergenic and often peak in late summer and autumn. High levels of specific IgE indicate 'sensitization' to this mold. Within an Allergy Profile, this result helps clinicians correlate respiratory symptoms with specific environmental triggers, allowing for targeted allergen avoidance or immunotherapy (allergy shots).

Why Context Matters
A positive IgE result indicates sensitization but does not confirm a clinical allergy. A patient may have high IgE levels without exhibiting symptoms upon exposure (asymptomatic sensitization). Conversely, local allergic rhinitis can occur even with negative serum IgE.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
