Alternative questions are:
should the panic ranges and reported reference ranges be the same for
corrected and non corrected calcium?
should a reference range be quoted for both or just one (but which one)?
should we have an EQA scheme for corrected calcium? (can we do a pilot
jonathan?)

Subject: Panic values for total calcium?
Dear colleagues,
I would appreciate getting your opinion to help settle an ongoing debate
related to total calcium panic values.
There are certainly two fractions of requesting physicians. One would
prefer only rather highly pathological concentrations (< 1.7 and > 3.5
mmol/l) whereas the other one states that less pronounced changes should
also immediately be communicated (< 1.9 and > 3.0 mmol/l).
I am fully aware of the influence of low albumina on calcium in ICU
patients and know of the advantages of ionised calcium. Still, some
agreement needs to be achieved.
Thank you very much for sharing your experience with us.
