- Digestive problems potentially related to food allergies
- Unexplained symptoms suggesting an allergen sensitivity
Preparation

- Inform your healthcare provider about any medications or supplements you are taking.
Procedure Description
- A blood sample is drawn from a vein, usually in your arm.
- The sample is sent to a laboratory where it is tested for the presence and concentration of IgG antibodies for specified allergens.
- Results are quantified and reported in units per milliliter or a semiquantitative range indicating the level of IgG antibodies.
Duration
The procedure for drawing blood takes approximately 5-10 minutes. Lab analysis may take a few days to a week to complete.
