How to Prevent Cloudy Plasma Donations

November 25, 2021

Contrary to popular belief, plasma isn’t always “yellowish” or “straw-coloured”, as it is often described. This protein-rich liquid component of blood can come in a variety of different hues, including reddish-orange, green, and milky white. The latter hue is often referred to as “cloudy plasma”.

When plasma is cloudy, it cannot be used to make life-saving therapies. Keep reading to learn more about what causes cloudy plasma and how you can prevent it!

What is Cloudy Plasma?

Cloudy plasma is plasma that is full of fats. Unlike healthy plasma, which is clear and yellow in colour, cloudy plasma has a milky white appearance. This naturally occurring phenomenon is known as lipemia. 

Is Cloudy Plasma Bad?

Plasma that is cloudy looking is caused by increased levels of plasma triglyceride concentrations. This can occur if a donor has eaten a fatty meal before donating plasma, and it renders the donation unusable

What Foods Make Your Plasma Cloudy?

Foods that are high in saturated and trans fats can raise your triglyceride levels and cause cloudy plasma. You should avoid eating the following foods on the day of your plasma donation: 

  • Fried foods, including chips
  • Fast food, like french fries, pizza, and burgers
  • High-fat dairy products

The Best Foods to Eat Before Donating Plasma

If you donate cloudy, or lipemic, plasma, you may be deferred or ineligible to receive full compensation for your donation. To prevent this scenario from happening, you should eat the following foods before donating plasma: 

  • Lean proteins
  • Low-fat dairy products
  • Fruits and vegetables
  • High-fibre whole grains
  • Beans, nuts, and seeds
