Allergen, Food, Potato
Also known as: POTATO
Use
This test measures allergen-specific IgE antibodies to potato, which can help identify whether a patient has an allergy to potato. By quantifying allergen-specific IgE levels, it aids in the diagnosis of IgE-mediated allergic responses to the food in question. Understanding these levels is essential for managing allergic conditions and preventing allergic reactions.
Special Instructions
Ensure that serum is separated from cells as soon as possible or within 2 hours of collection. The minimum volume required for the test is 0.25 mL of serum. Refrigerate during storage/transport. Use the ARUP Standard Transport Tube for specimen submission.
Limitations
The clinical relevance for results in the range of 0.10-0.34 kU/L is undetermined and intended for specialist use. Although the test reflects concentrations of allergen-specific IgE, these levels may not correlate directly with clinical reactions and may not align with skin test results. A negative result does not rule out potential clinical allergy or anaphylaxis.
