Abstract

A method and device for the diagnosis of gastrointestinal allergy. The method and the device expose a surface to at least one antigen at a fixed depth. The device includes an application point each having an antigen allowing for the application of the antigen to the surface at a fixed depth. The device may include multiple applications points each with an antigen for simultaneously applying the antigens to the surface.

Claims (15)

1. A method to diagnose a gastrointestinal allergy comprising the steps of:

providing a device including a plurality of application points each containing an antigen;

introducing the device into a colon;

exposing a surface of the colon to the antigens at a fixed depth by establishing contact between the surface and the plurality of application points; and,

observing a reaction of the surface to the antigens,

wherein a plurality of different antigens are exposed to the surface at a fixed depth simultaneously and, wherein the surface that is being observed is within the colon when the observing step is being performed.

2. The method of claim 1 wherein the device is a patch.

3. The method of claim 1 wherein the device is a capsule.

4. The method of claim 1 further comprising the step of removing the device from the colon.

5. The method of claim 3 further comprising the step of opening the capsule.

6. The method of claim 3 wherein the step of exposing a surface to the antigen includes the step of scratching the surface.

7. The method of claim 3 wherein the step of exposing a surface to the antigen includes the step of penetrating the surface.

8. The method of claim 1 further comprising the step of taking visual readings of the colon exposed to the antigens periodically up to a total period of 1.5 hours.

9. The method of claim 8 wherein the visual readings of the colon exposed to the antigens are taken every minute for a total period of 20 to 30 minutes.

10. The method of claim 1 wherein the device is introduced to the colon in a cecal portion of the colon.
