Allergens, Weed Profile 5
Also known as: WEED PAN 5
Use
The Allergens, Weed Profile 5 measures the concentration of allergen-specific IgE antibodies in the serum to assess allergic sensitization. It includes analysis of common weed allergens such as Common Ragweed, Dandelion, Giant Ragweed, Russian Thistle, and Sagebrush. The test categorizes results into probability classes that correlate with the likelihood of IgE mediated allergic reactions, which can be useful for allergy diagnosis and management.
Special Instructions
It is essential to separate the serum from cells as soon as possible, preferably within 2 hours of collection. The test results, especially in the range of 0.10-0.34 kU/L, should be interpreted in conjunction with clinical history and in vivo reactivity to specific allergens, as clinical relevance is undetermined.
Limitations
The concentrations of allergen-specific IgE determined by this test may not directly correlate with the severity of clinical allergic reactions or skin test results. A negative IgE test result does not completely rule out clinical allergy or even anaphylactic reactions. Clinical correlation with patient symptoms and history is crucial for accurate diagnosis.
