Why is plasma yellow in color?
When isolated on its own, blood plasma is a light yellow liquid, similar to the color of straw. Along with water, plasma carries salts and enzymes. The primary purpose of plasma is to transport nutrients, hormones, and proteins to the parts of the body that need it.
The color of the plasma varies considerably from one sample to another, ranging from only barely yellow to dark yellow and sometimes with a brown or orange tinge also. In addition to the varying shades of yellow color, some plasma samples are clear and some are milky or turbid.
- Your blood is actually always red! Blood in your veins has very little oxygen and is a dark red color that looks almost blue when covered by your skin. Your arteries have bright red blood because it has a lot of oxygen in it that is being carried throughout your body to be used by tissues.
- Different gases are used inside plasma balls, and these gases glow differen colors. Neon has the famous bright orange glow, argon is a deep purple, nitrogen is a reddish purple.
- The other cause for a green plasma is an elevation in ceruloplasmin, which is copper bound to alpha2 globulin and has a blue-green color. Elevated ceruloplasmin levels are found in pregnancy, after estrogen administration, and rheumatoid arthritis.

- Your doctor inserts a thin needle through your skin, into your liver and draws a small sample of tissue. A laboratory tests the tissue for excess copper. Genetic testing. A blood test can identify the genetic mutations that cause Wilson's disease.
- Wilson disease is an inherited disease that causes the body to retain too much copper. Copper deposits in the liver, brain, kidneys, and eyes eventually cause tissue damage and scarring that makes the affected organs stop working properly.
- Wilson disease is an autosomal recessive disease, which means it occurs equally in men and women. In order to inherit Wilson disease, both parents must carry one genetic mutation (abnormal alteration in the gene) that each parent passes to the affected child.
Hemolysis of blood samples. Red blood cells without (left and middle) and with (right) hemolysis. If as little as 0.5% of the red blood cells are hemolyzed, the released hemoglobin will cause the serum or plasma to appear pale red or cherry red in color.
- Since arteries carry oxygen-rich blood away from the heart and veins carry oxygen-depleted blood back to the heart, some people believe that veins appear blue because blood without oxygen is blue. But it's not true! Blood is always red. Blue light does not penetrate human tissue as deeply as red light does.
- RBCs account for approximately 40 to 45 percent of the blood. This percentage of blood made up of RBCs is a frequently measured number and is called the hematocrit. The ratio of cells in normal blood is 600 RBCs for each white blood cell and 40 platelets.
