Hi I'd be so grateful if anyone can give me some help in understanding these immunology results as I don't understand what they mean. To give some context - I'm constantly coming down with viral and bacterial infections and I take a lot longer (than healthy people) to get over these infections. I also have several autoimmune diseases (eg. I take insulin, thyroid meds and steroids for Adrenal insufficiency). I also have the usual fatigue/PEM/sore throats/unrestful sleep. My doctor who ordered the tests for me is a generalist (not an immunologist) so I'm trying to find out as much as I can myself. I've highlighted the results that are high or low in bold. T 3 (CD3+) + 87.3 % [67-83] B Lymphocytes (DR,CD19+) 5.7 % [5-12] T4 (CD4+) + 59.5 % [40-59] In absolute value + 2052 [312-1306] T8 (CD8+) 29.7 % [22-37] In absolute value + 1024 [175-834] Ratio T4/T8 2.00 [1.11-2.54] T4 memory + 37.8 % [12-37] Ratio T4M/T4 0.64 [0.34-0.83] Cytotoxic T8 26.6 % [16-29] T8 suppressor - 2.8 % [3.0-14.0] T8c/T8s + 9.50 [1.5-6.5] Geactiveerde T(CD3+DR+) 1.7 % [0.0-4.2] NK1 (CD8-,CD57+) - 2.5 % [3.6-13.2] NK2 CD3+(CD16+/CD56+) 2.1 % [1.2-5.1] NK3 (CD3-,CD16+/CD56+) - 1.6 % [6.9-18.3] Lymphocytes (CD5) + 88.7 % [54-80] Thanks so much in advance for any help you can give me in understanding these results. PS do any of these tests say anything about my NK Cell Cytotoxicity level (eg. function). edited to change text color.
