Cat Dander Specific IgE

Unit
kU/L

This test measures the concentration of Immunoglobulin E (IgE) antibodies specifically directed against cat dander proteins (e.g., Fel d 1). In the context of an Allergy Profile, it quantifies the degree of sensitization. When an individual with high specific IgE is exposed to cat dander, it triggers mast cell degranulation, leading to allergic rhinitis, conjunctivitis, or asthma symptoms.

Why Context Matters

The presence of specific IgE (sensitization) does not always correlate with clinical symptoms (allergy). Some patients have high IgE levels but remain asymptomatic upon exposure, while others may have low levels but react strongly.

Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
