Ummmm... well, depending upon what the units are there?
No offense, but I'm kind of chuckling that you consider that to be a real "rise" in IgE. My DD's peanut IgE numbers have never been lower than
18. Yeah-- no decimal point. Mostly, they've been off-scale. On the other hand, her other numbers drift all over the place.
I understand that some people tend to just have very low IgE, but mostly, those values
tend to be +/- 0.5 kU/L anyway, so who knows what it means...
and even if it were real (which isn't something that one can really say, as noted, since on a different day that same blood draw might result in a number quite different)...
IgE goes up... it goes down... it stays the same...
because...
nah. Just kidding. I got nothin' here. If there IS a legitimate reason why IgE values go up and down, nobody knows what it is. I've always voted on the tides. Weather patterns in Spain are another popular choice, as it the price of tea in Beijing.
Remember, IgE is just a number-- it's not the allergy itself. So it doesn't necessarily mean anything about your allergy one way or the other.
