Which color of tube is designated for fluoride-oxalate in the material?

Explanation:
The main idea is matching the additive to the tube color in this material’s color-coding scheme. Fluoride-oxalate tubes contain sodium fluoride (a glycolysis inhibitor) and potassium oxalate (an anticoagulant). This combination preserves glucose levels and prevents clotting, making the tube ideal for glucose testing and other plasma-based assays. In this material, that additive is designated with a yellow top, so the yellow tube is the correct choice. Keep in mind that tube color codes can vary between systems, so always check the specific color chart used by your facility.
