Name |
Corrected Calcium |
Alternative name/Profile |
Adjusted Calcium |
Department |
Biochemistry |
Investigation |
This is calculated (see below) based on the measured total calcium concentration adjusted for albumin concentration. It is used as a practical means of trying to provide an alternative measure of the physiologically active form of calcium in the absence of ionised Ca assay. It is not valid if the albumin is <20g/L. |
Specimen type |
Derived from the Calcium and Albumin results |

Notes |
Formula for Corrected Calcium Corrected Calcium (mmol/L) = (44 - Albumin (g/L))*0.0139 + measured Calcium (mmol/L) NOTE: This calculation may not be valid if the Albumin is <20g/L See individual tests for interferences and recommendations Separate from clot or cells as soon as possible. Calcium decreases with prolonged exposure to clot. Sera from patients receiving EDTA treatment for Hypercalcaemia unsuitable for analysis. EDTA anti-coagulant must be avoided. EDTA contaminated samples will not be reported for Calcium. Refer to order of draw to prevent contamination |
