Our son was diagnosed with a dangerous peanut allergy by another doctor. However, I was a little unsure about some of the numbers on the tests, so I sought out Doctor O’Connor for a second opinion. I am so glad that we did. When Dr. O’Connor reviewed the records, she agreed that the numbers didn’t seem to add up. She ordered her own set of tests, and upon review agreed that we should allow my son to participate in an oral challenge. We were so very happy to find out that he passed the oral challenge, and now we know that he can safely eat peanuts. How awful it would have been to have lived the rest of his life with a mistaken diagnosis! I am so glad that Dr. O’Connor was willing to give the oral challenge a shot!
