I don't post often, but I've been through alot with alergies! They aren't fun.

Do you know if the test is a blood test, or not? Jasper had the blood alergy tests, and neither showed anything. I've heard they are very inaccurate, but were the only kind available to us here.

That's the most I can say without more information. I hope you are able to find out what's causing Nova's, or atleast narrow it down. Good luck!
