Potato, White
Use
The Potato, White test measures the levels of specific Immunoglobulin E (IgE) antibodies in the serum to identify allergic sensitizations to white potato proteins. It is used to assess potential allergic reactions that may cause symptoms such as itching, hives, or asthma. The test aids in diagnosing food allergies and is often part of a broader allergy assessment program to understand a patient's specific allergic triggers.

Limitations
This test only measures the presence of IgE antibodies specific to white potato and may not detect all forms of potato allergies. False negatives can occur if the allergen extract used does not contain the specific allergenic proteins causing a patient's symptoms. The test does not indicate the severity of allergic reactions and should be interpreted alongside clinical history and additional tests if necessary.
