What are the causes of serum looking like milk?

Serum can appear milky due to the presence of high levels of lipids, a condition known as lipemia. This can occur after a meal rich in fats, leading to elevated triglyceride levels in the blood. Additionally, certain medical conditions, such as Diabetes mellitus or pancreatitis, can cause lipemia. In rare cases, an increase in chylomicrons, which are lipoproteins that transport dietary lipids, can also contribute to this milky appearance.
