I had some blood work done and the Insulin-Like Growth Factor I came back low 81 and normal is 97-238. Also, my Immunoglobulin A (559 and normal was 70-400) and Immunoglobulin M (242 and normal is 40-230) both came back high. I took these results to my doctor and she did not know what they were. She is suppose to find out but if anyone knows I would really appreciate any information. I got these results as part of a study because our drinking water is contanimated with C8. I have FM and thyroid.
