20 December 2019 (Friday) - Red Cell Folate
Today our department stopped performing red cell folate assays. This decision has been taken following on from review of the clinical utility of the RCF test in comparison with serum folate assay.
Now I was always of the opinion that serum folate just showed you how much folate was in your last meal whereas red cell folate gave you a reflection of folate intake over the last few months. It would seem that opinion has changed.
One lives and learns...
