<<Disclaimer: Verify this information before applying it to your situation.>> Thanks for all the responses about our son's gluten challenge. After forwarding Dr. Murray's excerpt on the gluten challenge to her, she has agreed to go ahead and have his anti body levels tested this week which will be three months exactly. If anti bodies are elevated she has agreed to do the biopsy. If not we will wait until the end of the summer. I will keep you all posted,thanks for your support.
