How low does a cap rast have to be for a food challenge? I know different allergists vary on this, but what have your allergists been saying about this?

On Apr 12, 2005

From the conference:

Challenges based on history of reactions, RAST results and importance of food in diet. Suggested RASTs to perform challenge (in pts with known allergy) MILK <2 KU/L Egg <2 KU/L Peanut <2 KU/L

Cut offs less clear for other foods (ie consider challenges at much higher levels).

This information was also featured in the latest FAAN newsletter, for those who are members.

Interesting....that is higher than I would have thought, at least for milk and egg. For people who have had challenges (or your kids) what was the cap rast and did they pass?

DS failed a milk challenge with a CapRAST of 2.4.

It was a very minor reaction and did not require any medication. Several bites of the trial food were ingested before he reacted.

Huh. Dd's egg has been under 2 for years. Holding at 1.13, but I am told this is still moderate allergy. becca

I know when dd`s cap rast to milk was 1.02 in 2004, he said it was not low enough for a challenge. As it turns out, he was right.

Here's what my dd's allergist said about a food challenge. "If you want it done, I don't recommend it, but you'll need to go to Duke Univ. Medical Center to have it done, they are about the only ones with a large enough insurance policy to handle the possible outcome." I was like "okie dokie! point well taken" I too, have allergies, and mine is to something in general anesthesia. I was sent to Baptist Hospital in N.C., and they tried to reproduce my reaction, but had to stop b/c they weren't allowed to give me the amount of meds they did in surgery to reproduce the reaction, b/c of insurance purposes. Meaning... they didn't want to kill me on their watch. I'm not trying to scare you, but I wouldn't willingly have dd ingest anything peanut. I know these docs are doing these food challenge studies, but I'm going to wait until they're done with the 2 yr study, and then hear what they have to say. I bet , if you really want to, you could do a skin test. Rub the "substance" on your child's arm, but I'd do it during your child's doctor's operating hours just in case.

What was the cap rast when your dd`s allergist said that?
