Final answer:
The yellow-top tube is utilized for genetic and platelet studies because it contains preservatives suitable for stabilizing blood components crucial for such tests,the correct option is B).
Step-by-step explanation:
The tube responsible for genetic and platelet studies is typically a yellow-top tube. This type of collection tube contains anticoagulant and preservative that support the stabilization of blood samples for such tests. Specifically, yellow-top tubes can be used for DNA, RNA, and molecular tests required in genetic studies but also include elements relevant for platelet function tests since they contain ACD (acid citrate dextrose) solution which is crucial for preserving platelets and other blood components.
When conducting platelet studies, it's important to note that other components like platelets, fibrinogen, and clotting factors are crucial. Yellow-top tubes are preferred for their ability to preserve these components. In comparison, other tube colors are associated with different tests and additives:
- Red-top tubes are used for tests that require clotted blood or serum.
- Blue-top tubes are specific for coagulation tests and contain sodium citrate.
- Gold-top or serum separator tubes contain a gel for separating serum after blood clotting.
In summary, for genetic and platelet studies that you're inquiring about, the yellow-top tube is the one typically utilized.
