Guest guest Posted February 8, 2010 Report Share Posted February 8, 2010 In our practice, serum thiamine is commonly ordered to assess thiamine status. We have read that serum thiamine reflects recent intake, whereas RBC transketolase activity better reflects body stores. Our lab says there is no test for RBC transketolase activity. Does anyone have any experience with this? Thanks. Ohlinger MS, RD, LD Clinical Dietitian Mercy Healthy Weight Solutions Quote Link to comment Share on other sites More sharing options...
Guest guest Posted February 8, 2010 Report Share Posted February 8, 2010 I wouldn’t be surprised if that test was used mostly in the research setting. My thought is that if the pt’s B1 status is low now it probably usually is, and it would be a good idea to go over their usual intake and recommend a B complex.
