Use

This test determines the presence of allergen-specific IgE antibodies to pork, which can aid in the diagnosis of pork allergy. It provides a quantitative measurement of IgE antibodies, which can help in assessing the risk of allergic reactions and guiding management decisions. The test is useful for evaluating patients with suspected food allergies and is essential for correlating laboratory results with clinical history and in vivo reactivity to specific allergens. However, it is crucial to note that negative results do not rule out clinical allergy or even anaphylaxis.

Special Instructions

Patients should avoid multiple encounters as part of test preparation, and the specimen should be collected using a serum separator tube. It is important to separate serum from cells as soon as possible or within 2 hours of collection. The serum should be transferred to an ARUP Standard Transport Tube. For multiple allergen orders, refer to the allergen specimen collection instructions provided by ARUP.

Limitations

The results of the allergen-specific IgE test may not correlate with the degree of clinical response or skin testing results when challenged with the specific allergen. Concentrations of allergen-specific IgE may not directly correlate with clinical allergy symptoms or predict the severity of allergic reactions. Therefore, correlation with clinical history and potential in vivo reactivity is essential for accurate diagnosis and management. The test results should be used as part of a comprehensive allergy assessment by a specialist.
