After drawing a blood sample from an animal that has recently eaten, which sample condition is most likely?

• A. Hemolyzed
• B. Lipemic
• C. Anemic
• D. Icteric

Answer: (B)

After a meal, fats are absorbed and enter the bloodstream as chylomicrons, which raises the level of triglycerides in the serum or plasma. This excess fat scatters light and gives the sample a milky, hazy appearance—this is described as lipemia. Because recent feeding directly leads to elevated lipids, lipemic samples are the most likely finding in a blood draw taken soon after eating. Hemolyzed samples look pink or red due to free hemoglobin from ruptured red cells, which is typically due to collection or handling issues rather than being related to feeding. Icteric samples are yellow from elevated bilirubin, often related to liver or biliary conditions, not specifically to a recent meal. Anemic refers to a reduced red blood cell mass, which is a systemic condition rather than a postprandial sample appearance.
