Test Catalog

Test ID: CAI    
Calcium, Ionized, Serum

Specimen Type Describes the specimen type validated for testing

Serum SST

Specimen Required Defines the optimal specimen required to perform the test and the preferred volume to complete testing

Container/Tube: Serum gel or serum gel microtainer

Collection Instructions:

1. Allow blood to clot for 30 minutes.

2. Serum gel tube/microtainer must be centrifuged within 1 hour of draw time. Centrifuge with stopper in place for 7 minutes at 3,000 rpm to ensure that the gel barrier separates the serum and cells.

3. Keep specimen anaerobic do not aliquot.
