|Mnemonic: ||[Ion Ca]|
|Name: ||Calcium, Ionized|
|Specimen: ||0.5 mL whole blood from a Green top tube or serum/plasma from a Red/Green SST. Tube must not be opened prior to analysis. |
If the analysis cannot be completed immediately, the SST should be centrifuged to separate serum/plasma from the cells. Once centrifuged, the sample is stable for approximately 3 days when refrigerated as long as the container has not been previously opened..
May also be collected in a heparinized blood gas syringe.
|Reference Range: ||1.1 - 1.3 mMol/L|
|Critical Range: || < 0.7 or >=1.6 mMol/L|
| Method: ||Ion Selective Electrode|
|Note: ||The test is included in a Blood Gas.|
