In the past I’ve had a positive skin prick test to an item, why does this not show up in my test results?

The two different test methods, skin prick test and IgE blood testing are completely different and should not be compared. Whilst the skin prick test shows a skin reaction from a solution applied to the skin, IgE blood testing detects antibodies circulating in the blood. A skin prick test can show a positive reaction, but an IgE blood test shows no detectable antibodies. It is always best to compare two tests of the same type to get a comparable result.
