Dear Roche users,
In order to check
whether or not we are in-line with national practice, please could anyone who
is NOT using the Roche kit insert recommended reference range for FT4 (12-22
pmol/L) email me with their reference range for FT4, and the source of data from
which the reference range was derived.
Thank you,
Jinny Jeffery,
Clinical Scientist,
