4+ allergy? is this the highest reaction?

I am confused.
My DS reaction was a 4+ to all nuts except pecans.

Does this also mean that he is more likely to have anaphylactic reaction with a first exposure?

He is 6 months old.

Anyone else have a baby or their child diagnosed when they were a baby? He was diagnosed by the percutaneous skin testing

Hi mom2sam. I am sorry to hear about all the fa's for your little baby. My dd had her first and only anaphylactic reaction when she was ten months old. Her spt (skin prick test) was a 4++ to peanut. However in our situation she has not had a reaction since. I have heard of many others who have had ana. reactions with levels of two. It is very unpredictable who/when someone is going to have a reaction and to what severity. Welcome to the board and ask any questions you need to, remember the majority started out at some time with little or no knowledge of fa's in the beginning.

My dd was diagnosed when she was 2. I gave her PB and she lit up with hives in about 10 seconds. I gave her Benedryl and that is all the further it went, no anaphylaxis. At that time we went and had testing done (blood test, not skin test) and she scored a 4+. The scale goes up to a 6, but a 4 is considered to be highly allergic. I don't think the score can indicate what type of reaction your baby might have (hives, trouble breathing, etc), but my understanding is that the higher the score the more likely that if there was contact with the allergen it would be a pretty good one. In my dd's case, her score actually went down over the years to a point at age 6 where she was down in the level 2+ range, but as soon as she came in contact with peanuts her level shot right back up to a 4+ again. Her reaction when she was a level 2 did seem milder than when she was a level 4, but i personally think that is all a crap shoot. If my kid scores above a 0, I am practicing full avoidance and I treat every contact as if it could be fatal.

I have seen on here that some peoples drs only say 4+ when referring to the SPT (Skin Prick Test) or 4++ and I'm not sure why exactly that is. The "4" is supposed to be milimeters of the wheal for that particular allergen. But whether or not it is a positive is based on the "control wheal" where they prick the skin with hystamine. I have heard people on the board say their child was positive for an allergy with a 3+ or even 2+ which would mean the control wheal must have been smaller.
I.E. the control wheal is 2mm then any of the allergens that create a wheal bigger than 2mm would be considered positive. When I had my DS tested at 3-4 months his allergist said anything over 4mm would be considered positive. His control wheal was indeed about 4mm and his peanut was 9+mm wheal. His dustmites tested a larger wheal but not bigger than the control wheal so he didn't consider those to be positive.
My DS has never had pn first hand. He has only been exposed to pn when I was pg and through breastmilk before I knew of his allergy. From everything I have read though and from my allergist, a positive is a positive and there is no way to know what the reaction might be. In addition each reaction to exposure could be different. One time it might just be hives, but the next could be ana.
I was just like you when I first learned of DS pa and that was the biggest question was the "what if" and unfortunatly there really is no answer. You will just learn a different lifestyle and even though you will be super cautious over things and stress about stuff you start to focus on other things than that particular "what if" question.

Hi - im very sorry to hear about ur allergy - im new to this too and it seems that we might have found out kinda the same way.
My son now 9 months (7 months at the time) was getting tested to milk and soy - since i thought that was what was causing his rash. Thank god that peanut is on the same stick as soy, cuz he scored a 4+. (better to find out that way then the other) And a 3 for egg whites (same stick as milk) which i think was causing the rash.
He has never had a reaction to peanuts, but they gave us an epi-pen and sent us home, told us to go peanut free and that was it.
It was later that week with my doctor that we learned the epi-pen is an overdose in babies and to be carefull using it. He wasnt able to tell me what kind of reaction he would have, just that it gets worse with each time.
So i just had to think back to times i ate peanut butter and what happened. There was no skin contact rashes from that and i played with him in the high chair while i was eating the pb. So i think he has had some exposure but limited.
I bought 'wet ones' wipes to wipe down high chairs and grocery carts (they r suppose to work the best) and i bought a book - the peanut allergy answer book - best purchase i made! got him a medic alert braclet, and started training my 4 year old to say no peanuts, no eggs.
just hang in there! its been 2 months for me and im getting the hang of it - slowly but thats ok.
