Hi Mary
Initial verification:
Our devices were checked against an existing ketone meter that was in service historically within the hospital.
We used both patient samples and also blood spiked with ketones
Ongoing uncertainty of measurement:
We calculate uncertainty and publish our own QC ranges based on performance data from our control software.
Kind Regards

Subject: Ketone testing
Dear All,
We have found a persistent negative bias on our Nova Biomedical Statstrip meter for ketones quality control level 1. Does anyone amend the ranges set by Nova? I have contacted Nova but they said they were not aware of this being done although they could not rule it out.
Secondly, how have other sites verified ketones? We tested against the meter then in use but it was only being used on Paediatric patients and we have done little on-going verification or cross site comparison (apart from EQA)since. Interested in what other sites have done.
Kind regards,
Mary
