Has anyone had Interleukin 2 Receptors tested? Mine was done 2 years ago and came back: <406 with range 406-1100. The neurologist who ordered said this indicated that my immune system was really busy fighting or something like that, but earlier this year a naturopath said that was an immune deficiency. I forgot all about it until I came across the test result page a few moments ago and googled it. Wikipedia says "CD25 deficiency or interleukin 2 receptor alpha deficiency is an immunodeficiency disorder associated with mutations in the interleukin 2 receptor alpha (CD25) (IL2RA) gene. The mutations cause expression of a defective α chain or complete absence thereof, an essential part of high-affinity interleukin-2 (IL-2) receptors. The result is a syndrome described as IPEX-like or a SCID." Although I have had some odd sort of things pop-up, I don't think I have anything IPEX-like or SCID. So, I ask: Have you had Il-2 Receptors tested? Is this common in PWME?
