Ordering the IgE Food Antibodies Test | Genova
The IgE Food Antibodies Test from Genova helps identify specific foods that may trigger immune reactions, such as hives, eczema, or digestive discomfort. This test measures IgE antibodies, which are linked to immediate food allergies and can cause symptoms soon after eating certain foods. Interestingly, some people may have high IgE levels to foods they rarely eat, which can still cause reactions if those foods are reintroduced.
Ordering this test can help you pinpoint foods that may be causing symptoms, even if they seem unrelated. Benefits of ordering include:
- Identifies specific foods that trigger immediate allergic reactions
- Helps guide dietary changes to reduce symptoms like skin rashes, headaches, or stomach pain
- Supports targeted elimination diets for clearer results
- Provides a detailed report for your healthcare provider to review
- Can reveal hidden food allergies that may not show up with skin testing
Who Should Consider Food Allergy and Sensitivity Testing
People who experience frequent stomach pain, skin rashes, or headaches after eating may benefit from this test. For example, someone who feels tired and bloated after meals but cannot figure out which food is causing the problem may find answers through this testing.
Ordering may also be helpful in these situations:
- Recurring sinus congestion or runny nose after eating certain foods
- Unexplained joint pain that seems to flare up after meals
- Children with eczema that does not improve with creams or medications
- Adults with migraines that start soon after eating
- People with asthma that worsens after eating foods like nuts or shellfish
Pinpointing food triggers can help reduce symptoms like bloating, cramps, or skin irritation by removing the problem foods from your diet. Delaying this test may mean continued symptoms and missed opportunities to make simple changes that could help you feel better. To get started, order the test and follow the instructions provided.
Preparing for Allergy and Immune Response Testing
Fasting is not required for the IgE Food Antibodies Test, so you can eat and drink as usual before your blood draw. Make sure to follow any instructions your doctor or healthcare professional gives you, as these may include specific steps for sample collection or timing.
