Allergen, Grass, Common Reed IgE

Also known as: REED POL

Clinical Use

Order Test

Use

This test is used to measure the concentration of allergen-specific IgE antibodies in the serum for the grass allergen, Common Reed. The results help assess the likelihood of an IgE-mediated allergic response upon exposure to this allergen. While the quantitative measurement of IgE levels provides an indication of sensitization, it does not correlate directly with the severity of clinical symptoms or skin test results. Therefore, test outcomes should be integrated with clinical history and in vivo allergen reactivity to manage and diagnose allergic conditions effectively.

Special Instructions

Patient preparation involves collecting blood in a serum separator tube. Serum needs to be separated from cells ASAP or within 2 hours, and then transferred to an ARUP Standard Transport Tube with a minimum volume of 0.25 mL. Specimen should be refrigerated during storage and transport. It is crucial to prevent hemolysis, icterus, or lipemia in specimens, as these conditions can lead to rejection.

Limitations

The concentration ranges provided are indicative of increasing levels of allergen-specific IgE but may not correlate precisely with clinical response or skin testing results. Even a negative test result does not exclude the possibility of clinical allergy or anaphylaxis. The test is designed for specialist evaluation when IgE levels are detected between 0.10-0.34 kU/L, as their clinical relevance is not established.
