Perform the following steps to convert Magnesium results
from mEq/L to mg/dL.
1. Multiply existing values by the conversion factor, 1.215.
2. Edit the following parameters as described in
Section 2,
Installation Procedures and Special Requirements
of the
AEROSET System Operations Manual
. The following
example uses values listed in the Abbott Clinical
Chemistry Magnesium package insert, Commodity
No. 30-3348/R6, March 2004.
3. On the
Base
page of the
Assay Configuration
screen, edit
the Units field from mEq/L to mg/dL.
4. Edit control mean values on the
CALIBRATOR/CONTROL
screen.
5. Verify all edits are saved.
6. Calibrate the Magnesium and/or Magnesium Urine assays
as appropriate.
7. Run two levels of controls to verify the calibration.
