Where to go for single IgG and IgE blood test?


(Bean) #1

I react to a lot of things, but I’m not currently working with an allergist. Somehow I have never been tested for a corn allergy or sensitivity. I think it would be worthwhile to run this test. My GP can’t order tests that are not in their system.

An internet search turns up a lot of options, but my usual self-order service (OYL) doesn’t carry either IgG or IgE for corn.

Who would you recommend for in the US with LabCorp as closest blood draw?

TIA

Your doc can 100% order a food allergy test. Typical dismissal.

No need for IgE testing, do you have an actual allergic reaction to it? You’d know if you were actually allergic to it. It’s the sensitivities that get us.

Keep in mind, this stuff changes based on our diets, and exposure levels. Being a keto’r, you’re going to hyper react to most carbs, even if you don’t really have an issue with them, if you’re doing CKD or TKD and exposed to them more regularly, that doesn’t happen.


or

You can use FSA/HSA money for them as well.

This is what you get back, (there’s a graphical pretty one on the website)

In this case it really isn’t in their system. She considers me tech savvy and let me help her look. I had the Labcorp order numbers and everything.

I do have and IgE type of reaction to corn. I’m not talking about chips- even corn starch as a filler in meds. Dextrose, some citric acid. But I have a similarly strong reaction to celery.

In this case I do want the blood draw at the lab rather than a finger prick, although those can be informative, for sure. ETA- I had one of those before. (Cerascreen) I came back as low level reaction to 100% of the foods with a stronger reaction to 9 others. ETA 2. Dug out my results. Forgot that one measured the IgE as well. I wasn’t IgE positive to corn in 2022, anyhow. Pondering…

An IgG reaction (should) mean real time allergic reaction to it, meaning get out the Benadryl…or worse. If you want the gold standard, you want Cyrex, but that crap is pricey, and they don’t deal with insurance. They do give you all their testing codes and sometimes people can get it partially covered, but it’s still pricey. The benefit of them is they also do cross-reactivity, so if your body is reacting to one thing, thinking it’s something else, you’ll get that. But again, the $$. Also, your doc needs to order that one, they don’t deal with consumers, but let you download the “kit” basically to give to your doctor.

Hubby did that one. His doctor ordered it. It was around $500 out of pocket. The results were interesting and the accompanying instructions were extensive. I’m not sure if it was accurate. He (still) has some serious gastro stuff going on, though.

Cyrex is literally the king in that space, it’s mostly top shelf biohackers and the disposable income types that regularly use them. I’d trust whatever came back, but even with accurate testing, there’s always the part where you figure out how to use it, it’s many times not a direct answer, but a direction to move.

When I did mine and saw what came back as causing a larger response, most of that was stuff I was overconsuming, backed off a little on most of it, next test those looked a lot better, then some other stuff rose up.
