Blood gas syringes contain high concentrations of calcium in their 'ion balanced' additives. with best wishes Richard Richard Mainwaring-Burton Consultant Biochemist Queen Mary's Hospital Sidcup, Kent 020-8308-3084 Please note new e-mail address : [log in to unmask] ________________________________ From: Clinical biochemistry discussion list [mailto:[log in to unmask]] On Behalf Of Hart, Tanya Sent: 12 August 2009 18:11 To: [log in to unmask] Subject: Increased calcium in neonates We have recently (over the last 3 weeks approximately) seen a slight trend towards increased calcium levels in our neonatal intensive care unit, with a cluster of abnormally high values. We cannot find an obvious cause for this (no significant change in QC data or patient means, not obviously connected to use of a particular analyser, sample evaporation or babies on TPN). We are Roche Cobas users (e501 chemistry modules) and wondered if any other users had noticed any similar trends? ..or had any suggestions as to possible causes?
