In the standing plasma test, what indicates the presence of both VLDL and chylomicrons?

• A. Turbid plasma only
• B. Creamy layer only
• C. Turbid plasma with creamy layer on top
• D. Clear plasma

Answer: (C)

In the standing plasma test, lipids separate when the sample sits undisturbed: turbidity means triglyceride-rich lipoproteins like VLDL are present, while a creamy top layer signals chylomicrons. Seeing both together—turbid plasma with a creamy layer on top—shows that both VLDL and chylomicrons are present. If only turbidity is seen, VLDL is predominant; if only a creamy layer appears, chylomicrons dominate; clear plasma means there’s no significant lipemia.
