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.
In this manner, what is the normal color of plasma?
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.
Why is some people's plasma green?
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.
What causes plasma to appear red?
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.
