• CA2D: 80 to 2000 mg/L (2 to 50 mmol/L)

up to 20 g/L (500 mmol/L) with postdilution

Conversion Factors
Conversion factors for calcium concentration:

• 1 mmol/L = 40.08 mg/L
• 1 mg/L = 24.95 μmol/L

Traceability
This method has been standardized against a primary standard material (SRM 956 c level 2).

Precision
Representative performance data on Cedex Bio Analyzers are shown. Results obtained in individual laboratories may differ.
Precision was determined in samples of three concentration levels. Coefficients of variation (CV) were calculated for in-run precision (n=21) and inter-run precision (on 10 days).

Mean	0.59 mmol/L (23.7 mg/L)	2.29 mmol/L (91.8 mg/L)	3.59 mmol/L (144 mg/L)
