Hi! My son is being tested for immune disorders and I just got some of his labs back and just wanted some info. He had blood work done in Nov and the resluts were low so he was given another prevnor vacc. and tested again two weeks later. His strep type 1,2,3,4,5,7F,8,9,10a,11a,12f,15b,17f,20, 22f and 33f are all less than .2 and are suspose to be greater than 1.0 I have searched the internet and cannot find any answers. Does anyone know what this might mean or know where I can find info. We have our first immunology appt next week but I would like info before. Thanks for any help or advice.
