How glutenized do you need to be for a cyrex test

[3nanest]

My son had blood work done Cyrex Labs. The array 3 & 4.  I didn't start having him eat grain foods until around noon the day before the test. They took his blood around 11:30 am the next day. My son felt his usual gelatinized symptoms but not as extreme as usual.  By that night though he was full on sick and took over a week to fully recover. I'm worried that he did not eat enough and long enough before the test for it to give accurate results. Does anyone have any experience or feed back for us. We are still waiting for the results.

I guess you could ask that company?  I have no clue what test they did.  Most of their tests are not considered legitimate.  There are no currently medically recognized tests for food intolerances.  I don't think they do the medical Celiac blood panel?  For the medically accepted tests, you must be eating gluten for many weeks before they work.

What is a gluten challenge?

A gluten challenge is the period of time when gluten is added back into a person’s diet to assist in the diagnosis of celiac disease. Antibodies take time to build into the blood stream before they can be detected through blood analysis. For a gluten challenge we recommend eating 1/2 slice of bread or a cracker each day for the duration of the challenge.

• Prior to blood testing we recommend 12 weeks of eating gluten.
• Prior to an endoscopic biopsy we recommend 2 weeks of eating gluten.

In the case of a severe reaction to gluten, a medical professional may opt to shorten the 12-week challenge and move immediately to an endoscopic biopsy.
