I would urge everyone to get, and keep, copies of all your lab results. I was diagnosed with chronic lymphocytic leukemia 14 years ago and have been getting IVIG infusions every 6 weeks since then. I also get labs done at the same time. Routinely I am assigned to a PA for a review of labs. While looking at my labs I noticed my abnormal lymphocytes had shot up dramatically and my lymphocytes had doubled in 3 months. Because none of those changes had been flagged on the labs the PA's weren't paying attention and just said "your labs look fine ." I had a routine visit with my primary and asked him about the lab results. He was alarmed and called my hematologist, which led to many additional labs and a course of Rituxin.
Please do yourself a favor and double check your labs for yourself. Don't depend on the doctor or PA to pick up on changes. It is YOUR life at stake, not theirs.
