Hi John The potential 'controversy' was over the performance of bilirubin on the analyser, not the use of the analyser for one-off bilirubin measurements. This would not seem to be apparent from your experience, but I remember some doubts from somewhere. I'll search my 'memory banks' ! Would your SCBU staff use the blood gas analyser to do JUST a bilirubin, or would they measure blood gases/electrolytes at the same time, even if the baby didnt require them ? Do you see what I mean ??
