What is Milky Blood?

Milky blood, often referred to as lipemic blood, is blood that has a noticeable milky or cloudy appearance due to a high concentration of lipids (fats). This condition is known as lipemia.

Understanding Lipemia

Lipemia occurs when there is an excessive amount of fats, like triglycerides and cholesterol, circulating in the bloodstream. When this happens, the normally translucent plasma portion of blood becomes opaque and milky.

How Lipemia Happens

• Diet: A common cause of lipemia is consuming a meal high in fat shortly before a blood draw.
• Metabolic Disorders: Certain metabolic disorders, such as diabetes, can lead to increased lipid levels in the blood.
• Genetic Conditions: Some individuals may have genetic conditions that predispose them to lipemia.

Appearance

When blood is lipemic, the plasma looks:

• Cloudy
• Milky
• Opaque

Impact on Blood Products

• Transfusions: According to our reference, while lipemic blood products appear milky, the lipemia itself does not affect the safety of the product for transfusion.
• Laboratory Analysis: Lipemia can interfere with some laboratory tests, potentially causing inaccurate results, making it crucial to note this when analyzing such samples.

Is Milky Blood Dangerous?

While the appearance of lipemic blood might seem alarming, it is important to understand that:

• Not inherently dangerous: According to the reference, lipemia itself does not affect the safety of blood products for transfusion.
• Underlying Conditions: Lipemia can be an indicator of underlying metabolic issues that need attention, therefore, addressing its root cause is necessary to avoid complications in the long run.
• Temporary Nature: In many cases, lipemia is temporary, often stemming from a recent high-fat meal.
