A low IgE might not warrant a full immunoglobulin panel on its own, but considering your symptoms and positive ANA, I would request one.
Autoimmune CVID Question - Immunoglobulin Panel27F | 5'8 | Caucasian | USA | Autoimmune concern | No current med except otc Tylenol/Ibuprofen | No smoking/drug use | Very rare drink, only celebratory (weddings, birthday, etc) |To keep this as short as possible, I am experiencing general widespread aches and pains (I say my bones hurt a lot/heavy feeling legs), muscle weakness, joint pain, rashes, petechiae, easy bruising, itchy skin, swollen left axillary lymph node, gastro problems (diarrhea to constipation), chronic sinusitis and extreme fatigue. I have had these symptoms for the past two years or so, but my rash has spread onto my hands and the swollen lymph node will not go down - it doesn't hurt but I do notice it in my arm pit and it is visual when I raise my arm. I went to the doctor, since all my complaints were kind of general and vague she ran an ANA - positive 1:160, speckled. I was sent to Rheumatology, the Rheumatologist checked for Lupus, said I do not look like a typical Lupus pt and all my other Rheum bloodwork was normal (ESR CRP etc). He explained healthy people have positive ANAs. He did want me to go to Dermatology for the rash. He didn't think it looked like Lupus but did say it looked suspicious. He agreed that something was wrong with me as he believes skin is a big indicator in overall health. I went to my original doctor to get a referral to Dermatology - she decided to run an allergy panel and refer me at the same time so the Dermatologist would have everything in my chart they may need. Everything was completely normal, no allergies at all except my igE was at 3 which she flagged as low on my chart, even though the reference said 2.5 was low.After looking low igE up, I am not a doctor so I obviously do not understand a lot of the terminology, but from what I can gather it seems that people with autoimmune conditions usually have a low igE. Not that it is not necessarily a diagnosing factor for anything, but that the two usually go hand in hand *from what I can understand.*My question is: should I request a full immunoglobulin panel? Does having a low igE warrant that? I wanted to touch base with my doctor about the igE but did not want to ask her for an unnecessary bloodwork if igE doesn't correlate with an immunoglobulin panel - if that makes any sense? lol.I have read about CVID and would like to rule this out in my medical journey.Hopefully this all makes sense! Thank you for your time!!
