Many thanks for sharing Tony, I'd similarly be interested in the comparison regarding glucose meters. We’ve recently had concerns raised by our neonatal team regarding glucose measurements consistently being much lower on the point of care glucose meters (Abbott PxP) in comparison to when measured by capillary sample on a blood gas machine. The levels from the glucose meter are below 2.0mmol/L with the blood gas showing closer to 4.0mmol/L, we've not had any samples sent to the lab for analysis in these cases. The neonatal team are very concerned with this difference between as well as the need to further bleed the babies.
Where the details have been provided to me by the Neonatal Unit, I have been able to investigate and at least determine that the samples did have haematocrits within the measurable range quoted by the manufacturer (I understand that there are of course a number of other limiting factors). I’d be interested to hear about your experiences in using POC glucose meters in neonates, if you’ve seen similar problems and also what equipment you use.
Many thanks in advance,
Aimée

Hi Tony,
Do you have further data for the glucose meters compared to the blood gas analysers? Do you have blood glucose activated on your blood gas analysers?
Kind regards,
Jayne

Here's one for sodium, potassium and haemoglobin. We also compared creatinine as this is available on the Radiometer 827. We do not routinely report chloride in the lab, ionised calcium is not possible, bilirubin was not activated on the blood gas analysers as it was calculated, not measured and didn't seem to compare well. Lactate wasn't done as numbers to the lab are very low. We did a three-way evaluation of glucose meters v blood gas v lab.
Hope this helps.

Hi all,
I was wondering if anyone has done a blood gas analyser evaluation of method performance (e.g. Na+, K+, Cl- glucose, bilirubin, lactate, Hb) in their Trust including blood gas analyser vs laboratory they would be willing to share?
