10 July 2019 (Wednesday) - Vitamin B12
During the average night shift (amongst other tasks) I perform a couple of hundred vitamin B12 assays. However…. Have I been wasting my time?
The standard assay just measures the total about of vitamin. Much of it is apparently metabolically inactive. There is a school of thought emerging that we should be measuring the active fraction.
I wonder how long this specialised test will take to get into routine labs?
