Dear All,
Apologies to non- Abbott users. Abbott are changing their calibration for the FT4 assay from a 2 point cal to a 6 point cal. Although Abbott quote there should be no difference between the results we have observed a negative bias during
our evaluation of approx 1mU/l on the 6 pt cal compared to the 2pt cal. This is replicated on both of our analysers. Has anyone else seen a similar picture ?
Many thanks
Carolyn
