A physician requests a complete analysis of a patient's blood composition along with a measure of their glucose levels after an overnight fast. How should the specimens be collected to meet these requirements?
The test for blood composition should utilize a tube containing EDTA, while the glucose levels should be measured using blood drawn into an antiglycolytic agent containing tube.
A coagulant-containing tube is used for the blood composition test and a tube with a preservative for the glucose levels.
Both tests can be performed from whole blood collected in a single heparinized tube.
Serum separator tubes should be used for the blood composition profile, and EDTA tubes would be appropriate for the fasting glucose test.
