Does comparison of Bayer Advia Centaur immunoassay result obtained on samples collected in four different Becton Dickinson Vacutainer tubes?
Only for cortisol did our findings support the bias described by MHRA. Based on our results, apart from vitamin-B12 and possibly cortisol, there may have been no significant influence on clinical decisions as a result of using the old BD SSTII Advance specimen tubes. New BD SSTII Advance tubes and plain tubes give generally comparable results. BD PSTII tubes should not be used for steroid hormone measurements on the Bayer Advia Centaur instrument.
These findings indicate that promoter sequence changes are unlikely to contribute to PJS.
