Thanks Sunny, Miss Sagi and Emski on the information regarding intrillipids. I have prescriptions for Clexane and prenisolone at home which is good. Hoping Dr W when he does my plan mentions the protocol for killer cells as I have sent him my test result which shows I have elevated killer cells. I have a few different FS over the years and none of them have intrillipids and I just want to throw everything at it. Do you have intrillipids done after transfer or only the 4 - 6 weeks following a positive result? I wouldn't be able to do this as my FS doesn't offer it.
