Which type of tube is appropriate for drawing a lipid profile?

The gold top serum tube is the appropriate choice for drawing a lipid profile because it contains a gel that aids in the separation of serum from the blood cells after centrifugation. This is essential for lipid profile testing, as accurate results require a clear serum sample without cellular contamination.

The red top serum tube does not contain any additives, which means while it can also be used for serum collection, it lacks the gel that enhances separation, potentially complicating the processing of the sample needed for precise lipid measurements.

The green top serum tube contains heparin, an anticoagulant, which is not ideal for a lipid profile because it can affect the lipid levels measured. The blue top serum tube, which contains citrate, is primarily used for coagulation studies and could also interfere with lipid analysis. Therefore, the gold top serum tube is specifically suited for lipid profiles due to its design for optimal serum separation.
