IgE blood test while being on immunosuppression drugs

[Frenky]

Hello,

A shot in the dark ... Anyone knows if there's true interaction between immunosuppression drugs and IgE blood test ?

I have 10++KUa/L on my teens, now I'm at 0.1 KUa/L ... theoretically, i'm ready for a skin test.

Thank you !

I would THINK that the answer is "potentially, yes."

I cannot find any information specifically about your question at AAAAI's Ask the Expert, however that is probably where I'd ask it.

You probably need an answer from a real guru in immunology, or at least someone very familiar with the literature in this specific area.

I just received the results from my last blood test, this time it's non-detectable (<0.10) for specific milk ige.

I'm still waiting for the Ige total .... I think if the result of it come at non-detectable, this will mean immunosuppresion drug suppress IgE (I think).

I see the normal of total ige should be <100KuA/L ... but I can't see anywhere what should be the minimum to be normal.

I don,t think this normal for someone to have zero IgE , correct ?

Scored a 32 for IgE Total

Did myself a SPT test (would not recommend it though ..) , scored a wheal of 11mm

Took like 2 ml of milk, no reaction 

So far so good

I just realized that it is the mean diameter I have to calculate, so I did around 8 or 9mm

I've had blood test and skin prick tests while i've taken Clemastine a couple hours before the tests and still all my tested foods showed up..

Yeah-- I think that the question here is whether or not SHORT-term-- or LONG-term, if any particular immunosuppressant has the ability to artificially depress IgE.

I think that the answer may be yes, LONG-term, but that it might also depend on the mechanism of the immunosuppressant in question.

(I say that as a scientist with some pharmacology background to bring to bear-- I haven't actually LOOKED at any literature in this area, assuming something even exists.)

Did the SPT test today, 5mm for milk, 0mm for casein, 0mm for betaglobulin

We are going for a challenge !!!

that it works out!!  Good luck.

I passed the test without problems 

Never ever loose hope, allergies can always disapear at what ever age !!
