Allergen, Weed, English Plantain
Also known as: ENGLISH
Use
The Allergen, Weed, English Plantain test is used to quantitatively measure specific IgE antibodies in serum to the English Plantain allergen (Plantago lanceolata). This test helps to assess the risk and probability of IgE-mediated allergic reactions in patients suspected of having an allergy to English Plantain. The correlation of these allergy laboratory results with clinical history and in vivo reactivity to specific allergens is essential for accurate diagnosis and management.
Special Instructions
Serum should be separated from cells as soon as possible or within 2 hours of collection for optimal results. Specimens should be refrigerated during transport to maintain integrity, and hemolyzed, icteric, or lipemic specimens are not acceptable for testing.
Limitations
The results showing allergen-specific IgE concentrations may not directly correlate with the degree of clinical response or skin testing results when challenged with the specific allergen. A negative test does not rule out clinical allergy or even anaphylaxis. Results in the range of 0.10-0.34 kU/L are intended for specialist use as their clinical relevance is undetermined.
