Allergen, Food, Oyster

Also known as: OYSTER

Clinical Use

Order Test

Use

This test is used to detect specific IgE antibodies to the food allergen Oyster, helping to evaluate and diagnose allergic reactions mediated by this allergen. Increasing IgE concentrations may indicate increased sensitivity to the allergen, although the result should be interpreted in the context of the patient's clinical history and other diagnostic parameters. The concentration of allergen-specific IgE measured does not always correlate with the severity of clinical symptoms or skin test results upon exposure to the allergen.

Special Instructions

Not provided.

Limitations

Results around 0.10-0.34 kU/L should be interpreted cautiously as their clinical relevance is undetermined. The concentrations of allergen-specific IgE detected may not be directly proportional to the clinical allergies experienced by the patient when exposed to the allergen. A negative result does not rule out the possibility of an allergy or anaphylactic reactions. Additionally, variations may occur due to different laboratory procedures, thus clinical correlation and history are indispensable in evaluating the test results.
