I spelled both parts of the name of the lab test (for where thiamin deficiency is suspected) incorrectly in my previous post: <There are five enzyme systems in the body that absolutely require thiamin as a catalyst for their process to go through to completion. Some of them take place in the brain, and lasting damage can result from lack of sufficient thiamin. I think one of them is detectable in blood cells by doing what is called an erytrocyte tranketolase test.> Erythrocyte Transketolase, or ETK, is the name of the test, for accuracy's sake.
