We use the formula CA+(0.02*(42-ALB)). All results outside our reference
range are checked by measuring a pH adjusted ionised Ca.(pH7.4) The
correlation is invariably very good.

Subject: Corrected Calcium
Some views on current practice would be appreciated. Do members:
1) Automatically issue a corrected calcium on all requests
2) What formulas are used?
3) Is correction valid at all albumin levels or just low levels.
Thanks
