Instructions
Centrifuge and send unopened gel-barrier tube with vacuum intact. It is critical that the vacuum not be disrupted. Exposure of the serum to room air causes a loss of carbon dioxide to the atmosphere. This changes the sample pH and can prevent the lab from measuring the ionized calcium. To ensure that testing can be performed, send a separate tube for ionized calcium and adhere a piece of labeling tape over the top of the tube with the following written on it "IONIZED CALCIUM-DO NOT OPEN."


Transport Container
Gel-barrier tube


Transport Temperature
Do NOT freeze.


Methodology
Ion-selective electrode (ISE)

Setup Schedule
Monday - Saturday 1st and 3rd shifts
