The cost of a red cell transketolase assay should keep the patient in thiamine tablets (GPB0.79 for 20) for many years. with best wishes Richard Richard Mainwaring-Burton Consultant Biochemist Queen Mary's Hospital (NHS mail a/c) Sidcup, Kent 020-8308-3084 [log in to unmask] _____ From: Clinical biochemistry discussion list [[log in to unmask]] On Behalf Of Ceridwen Coulson [[log in to unmask]] Sent: 15 July 2009 09:24 To: [log in to unmask] Subject: Thiamine deficiency Dear All, Have a persistent request for trying to confirm a diagnosis of thiamine deficiency on a patient who has been in our ITU, now with Neurology. She has been on vitamin supplementation for 2 weeks, and is improving. Being pressed to see if any way of now confirming a diagnosis, either with a current test, or on any retrospective samples that might be around our assorted labs in North Bristol. I've tried to damp down their hopes, but just said I'd ask our expert mailbase! Blood or urine or any other body fluid? Thiamine itself or red cell transketolase? Would welcome any ideas, or reinforcement that too late now to confirm with a biochemical test. many thanks, Ceridwen North Bristol NHS Trust - www.nbt.nhs.uk DISCLAIMER: The information in this message is confidential and may be legally privileged.
