Tomato IgG
Use
The test measures Immunoglobulin G (IgG) antibodies specific to tomato, which may indicate an immunologic sensitization to the tomato allergen. While not definitive for diagnosing food allergies, it can be used in clinical situations to identify foods for diet elimination and challenge in patients with food-related complaints.
