Test ID: CAI    
Calcium, Ionized, Serum

Specimen Type Describes the specimen type needed for testing

Serum SST

Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.

Container/Tube: Serum gel or serum gel Microtainer

Specimen Volume: Full tube

Collection Instructions:

1. Allow blood to clot for 30 minutes.

2. Centrifuge with stopper in place for 10 minutes at 3,000 rpm to ensure that the gel barrier separates the serum and cells.

3. Keep specimen anaerobic (do not transfer).

4. Serum gel tube/Microtainer must be centrifuged within 1 hour of draw time.

Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.

1.75 mL in a 3.5 mL serum gel tube or 1 full serum gel MICROTAINER
