Ragweed, Short
Also known as: Common Ragweed, Short Ragweed
Use
The Ragweed, Short test measures specific IgE antibodies present in a patient's serum, specifically targeting short ragweed pollen allergens. This test is important for patients exhibiting allergic symptoms such as rhinitis, asthma, and eczema during the ragweed season. It helps in diagnosing and managing allergic responses by determining the level of allergen-specific IgE, aiding clinicians in tailoring treatment plans including allergen avoidance, pharmacotherapy, or immunotherapy.
Special Instructions

Limitations
The test's sensitivity may be affected by the presence of potential cross-reactive components in the serum. High total IgE levels could also lead to non-specific binding, possibly affecting the test's specificity. Additionally, while this test provides information on sensitization, clinical correlation is essential as the presence of specific IgE does not always predict symptomatic allergic reactions. Test results should be interpreted along with the patient’s clinical history and other diagnostic findings.
