I'm wondering how accurate skin tests are...

Yesterday, we went for a follow up at the allergist...
We only did SPTs and there was no change in size of the welts for her allergies to wheat and eggs. It was a little smaller on the barley.

However, one thing we saw was that dairy reacted barely above the histamine level when last time it was over 1cm! That is the one major allergen we think (thought) she was ana to! Also, she reacted strongly (almost 1 cm) to mustard, which is new to us, but could possibly explain her 2nd ana reaction...

We haven't done RAST tests yet, but our allergist said we'll do it next appointment (in 6 months) to follow the evolution of everything.

But with yesterday's results, I'm curious on how accurate these SPT's are. Could she really be starting to outgrow allergies or was it just a fluke?

Anyone have seen anything like this?

Me - Kim - No allergies
DH Ben - 31 - Allergic to nuts and peanuts, lots of environmental allergies.
DD Anne - 4 - Asthma. Allergic to dairy, eggs, mustard, kiwi, peanuts, wheat and barley... for now...
DS Francois - 1 - No allergies so far...
