Allergen, Occupational, Latex IgE, Enhanced
Also known as: LATEX
Use
This test measures latex-specific IgE antibodies, which are indicative of an allergic response to latex. It helps in diagnosing latex allergy and is essential for managing patients who might have occupational exposure to latex or related materials. The test results assist in clarifying the potential risk of IgE-mediated clinical reactions, including urticaria, asthma, or anaphylaxis, upon exposure to latex.
Special Instructions
Not provided.
Limitations
The concentrations of allergen-specific IgE detected by this test may not correlate with clinical symptoms of allergy. Clinical history and in vivo testing should be considered for a comprehensive assessment. A negative result does not rule out the presence of a clinical allergy or the possibility of experiencing anaphylaxis on exposure to latex. Cross-reactivity with other allergens, including certain foods or pollen, should be taken into account.
