Clinical Chemistry Laboratory

Overview

The Core Lab Chemistry Laboratory performs a wide variety of tests that include:

The Chemistry Laboratory is open 24 hours, daily. All blood gas testing is run on a Stat basis. General Chemistries are available on a Routine and Stat basis (results available within one hour). Special chemistries are available on a Routine basis. Also, Therapeutic drugs and Toxicology screens are available on a routine and stat basis. Refer to the Chemistry Stat List for test/status information.

Blood Gas Specimens

Blood gas specimens require a full name of the specimen collector, sealed capped air tight in a heparinized syringe with no bubbles. Proper mixing at the time of collection is essential to prevent clot formation.

Specimens transported via the pneumatic tube system should be double bagged. Blood gas specimens delivered by courier should be on ice and bagged. The requisition form accompanying a blood gas specimen must have the date and time of collection and the collector's full signature. Attach Epic label to second copy of blood gas slip.

For ionized Calcium test, a full 0.7 mL of whole blood in a 1 mL heparinized syringe or 2 mL in a 3 mL syringe is required.
