Hi everyone, I just needed a bit of help interpreting the meaning of some of my recent blood tests. I'm particularly intrigued about the number for immunoglobulin, which seem at the edge of being deficient, in light of my recent diagnosis for ME/CFS. Here's what I got: While my overall IgG numbers are low, notice how my IgG 1 and IgG 3 are just slightly above of the marker for deficiency. Basically borderline deficient on those two. I did a quick search online that explained some of the IgG subclasses, and IgG 1 is related to protein/polypeptide antigens, and that IgG 3 is associated to ME/CFS, fibro, and lung infections. What does this all mean in the context of my recent diagnosis? Also, my HNK1 lymph levels were alarmingly low: CD8-CD57: 1.8%, abs 40 /uL For the record, my titers for EBV VCA and Nuclear were very high (>8.0), and also high for HHV6. I would appreciate it if someone can decipher the IgG numbers for me, and what can be done, if anything. Thanks!
