- Sample Type
- Standard
- Fasting
- No
- Unit
- kUA/L
This test measures the concentration of Immunoglobulin E (IgE) antibodies directed specifically against Cefaclor, a second-generation cephalosporin antibiotic. It is used to identify Type I (immediate) hypersensitivity reactions. In the context of an 'Allergy Profile With Drugs', it helps clinicians determine if a patient is sensitized and at risk for anaphylaxis, urticaria, or angioedema upon exposure to this specific drug.

Why Context Matters
Cross-reactivity is a major factor; patients allergic to Penicillin or other Cephalosporins may show a positive result due to similar beta-lactam ring structures. Conversely, a negative IgE test does not rule out non-IgE mediated reactions (like SJS/TEN or serum sickness).
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
