Bit of background.... DS is 4.9yrs old. Between 6 months & 18 months he ate hoummous a few times & come up red & blotchy afterwards. Being already allergic to egg & dairy his consultant did a rast test on him which came back positive (0.47 out of total IgE of 17). Just before his second birthday he had what I felt at the time was quite a significant reaction after accidentally eating a snack containing sesame seeds. His reaction was a cough & his lips seemed a bit swollen & I think he also had a bit of a red flush.
Since then we have strictly avoided sesame & much to my surprise about 9 months after the last reaction at his next appointment, he skin prick tested negative to sesame. I was convinced this was a false negative but his RAST result then came back negative too. The results came back the same the following year too. His consultant has therefore recommended a sesame challenge which is booked for tomorrow.
I know the skin prick to sesame isn't the most reliable and the IgE levels can falsely slip into negative so I am feeling really apprehensive about tomorrow but I want to have my nerves under control for DS's sake.
Has anyone got any words of wisdom for getting in the right frame of mind for a challenge (somehow I wasn't nearly as nervous about the egg & dairy challenges he had to do) & also any experiences with sesame challenges (passes & fails)? I have no idea where to set my expectations.
