Hi there - this is my first time on. I have a PA child and just received the second RAST results and am a little confused. First time it was a level II( child was about 3) now( child is 6) it is off the charts they had to dilute the sample to get an actual number so now it is a level VI - we are so careful and have had no reactions since the diagnosing reaction. How can this be? Has anyone had an experience with false positives or retests having different levels?
I am starting to panic as I thought we were doing well but doesnt the elevated level mean exposure has happened?
Any input would be welcomed.
thanks

I do understand the disappointment.
No, a higher level does not mean exposure occurred.
Many other posters have the same situation. My son is almost 11 and has been dealing with PA for 10 years. His original reaction was from ingestion and his other reaction was from contact at age 5 (played with a child who had eaten peanutbutter for breakfast). He has had no other reactions and no known exposures except these. His numbers went up 9 points since last Oct. (level 4 to 5).

DD's increased as well, with no known exposures/reactions. In one year (just diagnosed last year at age 3) it's gone up right about 10 points.

thanks so much for your replies- I think I expected for the levels to stay the same or go down and when I was told that they were out of range- high I started to panic. We will have a retest just to make sure - its interesting that the levels can rise without exposure. thanks again for your replies and stay safe!

My DD went up off the charts as well the second time she was tested as well, she has always been a level VI. My allergist explained that sometimes the lab readjust the numbers and that you can't always pay attention to them. He also said the higher the number doesn't mean they have been exposed it just means DD will never outgrow.

My son's PA is off the charts too. I was very upset when I found out. From what I understand the numbers do go up and down.

When my ds#1's RAST dropped 75% but still stayed a class 4 she explained that this was actually 'good' because most kids IgE rises through childhood and peaks in the early teens and then starts to drop again in general. So numbers can and will go up regardless of exposure.
Then again I also feel it's virtually impossible to insure NO exposure even if there's no rxn...whether this has any impact nobody really knows...might be good or bad! But you'd have to live in a bubble to never touch or inhale at least miniscule amounts of peanut protein.

just got back my ds test for this year and wanted to share...I guess the numbers go up and down according to what I read...
his RAST history for peanut is:
2004 he had 8.37 class 3.....
2006 22.60 class 4...(after ingestion)
2007 8.21 class 3....(after strict avoidance) doctor said it is really hard to say if his number dropping means anything or not. He said continue with avoidance and we will see what the numbers do next year. He said that if the number reduces by half next year he would then think that he may be outgrowing it.

Blood tests over a 5 year span. >100, then 64, now back up to >100. No reactions during that time.
